Auto-configuration vs. Annotation-based configuration

The question most often asked is, "What Spring Data for Apache Geode/Pivotal GemFire annotations can I use, or must I use, when developing Apache Geode or Pivotal GemFire applications with Spring Boot?"

This section will answer this question and more.

Readers should refer to the complimentary sample, Spring Boot Auto-configuration for Apache Geode & Pivotal GemFire, which showcases the auto-configuration provided by Spring Boot for Apache Geode/Pivotal GemFire in action.

Background

To help answer this question, we must start by reviewing the complete collection of available Spring Data for Apache Geode/Pivotal GemFire (SDG) annotations. These annotations are provided in the {spring-data-geode-javadoc}/org/springframework/data/gemfire/config/annotation/package-summary.html[org.springframework.data.gemfire.config.annotation] package. Most of the pertinent annotations begin with @Enable…, except for the base annotations: @ClientCacheApplication, @PeerCacheApplication and @CacheServerApplication.

By extension, Spring Boot for Apache Geode/Pivotal GemFire (SBDG) builds on SDG’s Annotation-based configuration model to implement auto-configuration and apply Spring Boot’s core concepts, like "convention over configuration", enabling GemFire/Geode applications to be built with Spring Boot reliably, quickly and easily.

SDG provides this Annotation-based configuration model to, first and foremost, give application developers "choice" when building Spring applications using either Apache Geode or Pivotal GemFire. SDG makes no assumptions about what application developers are trying to do and fails fast anytime the configuration is ambiguous, giving users immediate feedback.

Second, SDG’s Annotations were meant to get application developers up and running quickly and reliably with ease. SDG accomplishes this by applying sensible defaults so application developers do not need to know, or even have to learn, all the intricate configuration details and tooling provided by GemFire/Geode to accomplish simple tasks, e.g. build a prototype.

So, SDG is all about "choice" and SBDG is all about "convention". Together these frameworks provide application developers with convenience and reliability to move quickly and easily.

To learn more about the motivation behind SDG’s Annotation-based configuration model, refer to the {spring-data-gemfire-docs-html}/#bootstrap-annotation-config-introduction[Reference Documentation].

Conventions

Currently, SBDG provides auto-configuration for the following features:

ClientCache
Caching with Spring’s Cache Abstraction
Continuous Query
Function Execution & Implementation
Logging
PDX
GemfireTemplate
Spring Data Repositories
Security (Client/Server Auth & SSL)
Spring Session

Technically, this means the following SDG Annotations are not required to use the features above:

@ClientCacheApplication
@EnableGemfireCaching (or by using Spring Framework’s @EnableCaching)
@EnableContinuousQueries
@EnableGemfireFunctionExecutions
@EnableGemfireFunctions
@EnableLogging
@EnablePdx
@EnableGemfireRepositories
@EnableSecurity
@EnableSsl
@EnableGemFireHttpSession

Since SBDG auto-configures these features for you, then the above annotations are not strictly required. Typically, you would only declare one of theses annotations when you want to "override" Spring Boot’s conventions, expressed in auto-configuration, and "customize" the behavior of the feature.

Overriding

In this section, we cover a few examples to make the behavior when overriding more apparent.

Caches

By default, SBDG provides you with a ClientCache instance. Technically, SBDG accomplishes this by annotating an auto-configuration class with @ClientCacheApplication, internally.

It is by convention that we assume most application developers' will be developing Spring Boot applications using Apache Geode or Pivotal GemFire as "client" applications in GemFire/Geode’s client/server topology. This is especially true as users migrate their applications to a managed environment, such as Pivotal CloudFoundry (PCF) using Pivotal Cloud Cache (PCC).

Still, users are free to "override" the default settings and declare their Spring applications to be actual peer Cache members of a cluster, instead.

For example:

@SpringBootApplication
@CacheServerApplication
class MySpringBootPeerCacheServerApplication { ... }

By declaring the @CacheServerApplication annotation, you effectively override the SBDG default. Therefore, SBDG will not provide a ClientCache instance because you have informed SBDG of exactly what you want, i.e. a peer Cache instance hosting an embedded CacheServer that allows client connections.

However, you then might ask, "Well, how do I customize the ClientCache instance when developing client applications without explicitly declaring the @ClientCacheApplication annotation, then?"

First, you are entirely allowed to "customize" the ClientCache instance by explicitly declaring the @ClientCacheApplication annotation in your Spring Boot application configuration, and set specific attributes as needed. However, you should be aware that by explicitly declaring this annotation, or any of the other auto-configured annotations by default, then you assume all the responsibility that comes with it since you have effectively overridden the auto-configuration. One example of this is Security, which we touch on more below.

The most ideal way to "customize" the configuration of any feature is by way of the well-known and documented Properties, specified in Spring Boot application.properties (the "convention"), or by using a {spring-data-gemfire-docs-html}/#bootstrap-annotation-config-configurers[Configurer].

See the Reference Guide for more details.

Security

Like the @ClientCacheApplication annotation, the @EnableSecurity annotation is not strictly required, not unless you want to override and customize the defaults.

Outside a managed environment, the only Security configuration required is specifying a username and password. You do this using the well-known and document SDG username/password properties in Spring Boot application.properties, like so:

Required Security Properties in a Non-Manage Envionment

spring.data.gemfire.security.username=MyUser
spring.data.gemfire.security.password=Secret

You do not need to explicitly declare the @EnableSecurity annotation just to specify Security configuration (e.g. username/password).

Inside a managed environment, such as Pivotal CloudFoundry (PCF) when using Pivotal Cloud Cache (PCC), SBDG is able to introspect the environment and configure Security (Auth) completely without the need to specify any configuration, usernames/passwords, or otherwise. This is due in part because PCF supplies the security details in the VCAP environment when the app is deployed to PCF and bound to services (e.g. PCC).

So, in short, you do not need to explicitly declare the @EnableSecurity annotation (or the @ClientCacheApplication for that matter).

However, if you do explicitly declare either the @ClientCacheApplication and/or @EnableSecurity annotations, guess what, you are now responsible for this configuration and SBDG’s auto-configuration no longer applies.

While explicitly declaring @EnableSecurity makes more sense when "overriding" the SBDG Security auto-configuration, explicitly declaring the @ClientCacheApplication annotation most likely makes less sense with regard to its impact on Security configuration.

This is entirely due to the internals of GemFire/Geode, which in certain cases, like Security, not even Spring is able to completely shield users from the nuances of GemFire/Geode’s configuration.

Both Auth and SSL must be configured before the cache instance (whether a ClientCache or a peer Cache, it does not matter) is created. Technically, this is because Security is enabled/configured during the "construction" of the cache. And, the cache pulls the configuration from JVM System properties that must be set before the cache is constructed.

Structuring the "exact" order of the auto-configuration classes provided by SBDG when the classes are triggered, is no small feat. Therefore, it should come as no surprise to learn that the Security auto-configuration classes in SBDG must be triggered before the ClientCache auto-configuration class, which is why a ClientCache instance cannot "auto" authenticate properly in PCC when the @ClientCacheApplication is explicitly declared without some assistance (i.e. you must also explicitly declare the @EnableSecurity annotation in this case since you overrode the auto-configuration of the cache, and, well, implicitly Security as well).

Again, this is due to the way Security (Auth) and SSL meta-data must be supplied to GemFire/Geode.

See the Reference Guide for more details.

Extension

Most of the time, many of the other auto-configured annotations for CQ, Functions, PDX, Repositories, and so on, do not need to ever be declared explicitly.

Many of these features are enabled automatically by having SBDG or other libraries (e.g. Spring Session) on the classpath, or are enabled based on other annotations applied to beans in the Spring ApplicationContext.

Let’s review a few examples.

Caching

It is rarely, if ever, necessary to explicitly declare either the Spring Framework’s @EnableCaching, or the SDG specific @EnableGemfireCaching annotation, in Spring configuration when using SBDG. SBDG automatically "enables" caching and configures the SDG GemfireCacheManager for you.

You simply only need to focus on which application service components are appropriate for caching:

Service Caching

@Service
class CustomerService {

  @Autowired
  private CustomerRepository customerRepository;

  @Cacheable("CustomersByName")
  public Customer findBy(String name) {
    return customerRepository.findByName(name);
  }
}

Of course, it is necessary to create GemFire/Geode Regions backing the caches declared in your application service components (e.g. "CustomersByName") using Spring’s Caching Annotations (e.g. @Cacheable), or alternatively, JSR-107, JCache annotations (e.g. `@CacheResult).

You can do that by defining each Region explicitly, or more conveniently, you can simply use:

Configuring Caches (Regions)

@SpringBootApplication
@EnableCachingDefinedRegions
class Application { ... }

@EnableCachingDefinedRegions is optional, provided for convenience, and complimentary to caching when used rather than necessary.

See the Reference Guide for more details.

Continuous Query

It is rarely, if ever, necessary to explicitly declare the SDG @EnableContinuousQueries annotation. Instead, you should be focused on defining your application queries and worrying less about the plumbing.

For example:

Defining Queries for CQ

@Component
public class TemperatureMonitor extends AbstractTemperatureEventPublisher {

	@ContinuousQuery(name = "BoilingTemperatureMonitor",
		query = "SELECT * FROM /TemperatureReadings WHERE temperature.measurement >= 212.0")
	public void boilingTemperatureReadings(CqEvent event) {
		publish(event, temperatureReading -> new BoilingTemperatureEvent(this, temperatureReading));
	}

	@ContinuousQuery(name = "FreezingTemperatureMonitor",
		query = "SELECT * FROM /TemperatureReadings WHERE temperature.measurement <= 32.0")
	public void freezingTemperatureReadings(CqEvent event) {
		publish(event, temperatureReading -> new FreezingTemperatureEvent(this, temperatureReading));
	}
}

Of course, GemFire/Geode CQ only applies to clients.

See the Reference Guide for more details.

Functions

It is rarely, if ever, necessary to explicitly declare either the @EnableGemfireFunctionExecutions or @EnableGemfireFunctions annotations. SBDG provides auto-configuration for both Function implementations and executions. You simply need to define the implementation:

Function Implementation

@Component
class GemFireFunctions {

  @GemfireFunction
  Object exampleFunction(Object arg) {
    ...
  }
}

And then define the execution:

Function Execution

@OnRegion(region = "Example")
interface GemFireFunctionExecutions {

  Object exampleFunction(Object arg);
}

SBDG will automatically find, configure and register Function Implementations (POJOs) in GemFire/Geode as proper Functions as well as create Executions proxies for the Interfaces which can then be injected into application service components to invoke the registered Functions without needing to explicitly declare the enabling annotations. The application Function Implementations & Executions (Interfaces) should simply exist below the @SpringBootApplication annotated main class.

See the <<[geode-functions,Reference Guide>> for more details.

PDX

It is rarely, if ever, necessary to explicitly declare the @EnablePdx annotation since SBDG auto-configures PDX by default. SBDG automatically configures the SDG MappingPdxSerializer as the default PdxSerializer as well.

It is easy to customize the PDX configuration by setting the appropriate Properties (search for "PDX") in Spring Boot application.properties.

See the Reference Guide for more details.

Spring Data Repositories

It is rarely, if ever, necessary to explicitly declare the @EnableGemfireRepositories annotation since SBDG auto-configures Spring Data (SD) Repositories by default.

You simply only need to define your Repositories and get cranking:

Customer’s Repository

interface CustomerRepository extends CrudRepository<Customer, Long> {

  Customer findByName(String name);

}

SBDG finds the Repository interfaces defined in your application, proxies them, and registers them as beans in the Spring ApplicationContext. The Repositories may be injected into other application service components.

It is sometimes convenient to use the @EnableEntityDefinedRegions along with SD Repositories to identify the entities used by your application and define the Regions used by the SD Repository infrastructure to persist the entity’s state. The @EnableEntityDefinedRegions annotation is optional, provided for convenience, and complimentary to the @EnableGemfireRepositories annotation.

See the Reference Guide for more details.

Explicit Configuration

Most of the other annotations provided in SDG are focused on particular application concerns, or enable certain GemFire/Geode features, rather than being a necessity.

A few examples include:

@EnableAutoRegionLookup
@EnableBeanFactoryLocator
@EnableCacheServer(s)
@EnableCachingDefinedRegions
@EnableClusterConfiguration
@EnableCompression
@EnableDiskStore(s)
@EnableEntityDefinedRegions
@EnableEviction
@EnableExpiration
@EnableGemFireAsLastResource
@EnableHttpService
@EnableIndexing
@EnableOffHeap
@EnableLocator
@EnableManager
@EnableMemcachedServer
@EnablePool(s)
@EnableRedisServer
@EnableStatistics
@UseGemFireProperties

None of these annotations are necessary and none are auto-configured by SBDG. They are simply at the application developers disposal if and when needed. This also means none of these annotations are in conflict with any SBDG auto-configuration.

Summary

In conclusion, it is important to understand where SDG ends and SBDG begins. It all begins with the auto-configuration provided by SBDG out-of-the-box.

If a feature is not covered by SBDG’s auto-configuration, then you are responsible for enabling and configuring the feature appropriately, as needed by your application (e.g. @EnableRedisServer).

In other cases, you might also want to explicitly declare a complimentary annotation (e.g. @EnableEntityDefinedRegions) for convenience, since there is no convention or "opinion" provided by SBDG out-of-the-box.

In all remaining cases, it boils down to understanding how GemFire/Geode works under-the-hood. While we go to great lengths to shield users from as many details as possible, it is not feasible or practical to address all matters, e.g. cache creation and Security.

Hope this section provided some relief and clarity.

Configuration Metadata Reference

The following 2 reference sections cover documented and well-known properties recognized and processed by Spring Data for Apache Geode/Pivotal GemFire (SDG) as well as Spring Session for Apache Geode/Pivotal GemFire (SSDG).

These properties may be used in Spring Boot application.properties files, or as JVM System properties, to configure different aspects of or enable individual features of Apache Geode or Pivotal GemFire in a Spring application. When combined with the power of Spring Boot, magical things begin to happen.

Spring Data Based Properties

The following properties all have a spring.data.gemfire.* prefix. For example, to set the cache copy-on-read property, use spring.data.gemfire.cache.copy-on-read in Spring Boot application.properties.

DiskStore properties can be further targeted at specific DiskStores using the {apache-geode-javadoc}/org/apache/geode/cache/DiskStore.html#getName--[DiskStore.name].

For instance, you may specify directory location of the files for a specific, named DiskStore using:

spring.data.gemfire.disk.store.Example.directory.location=/path/to/geode/disk-stores/Example/

The directory location and size of the DiskStore files can be further divided into multiple locations and size using array syntax, as in:

spring.data.gemfire.disk.store.Example.directory[0].location=/path/to/geode/disk-stores/Example/one
spring.data.gemfire.disk.store.Example.directory[0].size=4096000
spring.data.gemfire.disk.store.Example.directory[1].location=/path/to/geode/disk-stores/Example/two
spring.data.gemfire.disk.store.Example.directory[1].size=8192000

Both the name and array index are optional and you can use any combination of name and array index. Without a name, the properties apply to all DiskStores. Without array indexes, all [named] DiskStore files will be stored in the specified location and limited to the defined size.

Apache Geode Properties

While is not recommended to use Apache Geode properties directly in your Spring applications, SBDG will not prevent you from doing so. A complete reference to the Apache Geode specific properties can be found {apache-geode-docs}/18/reference/topics/gemfire_properties.html[here].

Apache Geode (and Pivotal GemFire) are very strict about the properties that maybe specified in a gemfire.properties file. You cannot mix Spring properties with gemfire.* properties in either a Spring Boot application.properties file or an Apache Geode gemfire.properties file.

Disabling Auto-configuration

If you would like to disable the auto-configuration of any feature provided by Spring Boot for Apache Geode/Pivotal GemFire, then you can specify the auto-configuration class in the exclude attribute of the @SpringBootApplication annotation, as follows:

Disable Auto-configuration of PDX

@SpringBootApplication(exclude = PdxSerializationAutoConfiguration.class)
public class MySpringBootApplication {

  public static void main(String[] args) {
    SpringApplication.run(MySpringBootApplication.class, args);
  }
}

Of course, you can disable more than 1 auto-configuration class at a time by specifying each class in the exclude attribute using array syntax, as follows:

Disable Auto-configuration of PDX & SSL

@SpringBootApplication(exclude = { PdxSerializationAutoConfiguration.class, SslAutoConfiguration.class })
public class MySpringBootApplication {

  public static void main(String[] args) {
    SpringApplication.run(MySpringBootApplication.class, args);
  }
}

The current set of auto-configuration classes in Spring Boot for Apache Geode & Pivotal GemFire include:

CacheNameAutoConfiguration
CachingProviderAutoConfiguration
ClientCacheAutoConfiguration
ClientSecurityAutoConfiguration
ContinuousQueryAutoConfiguration
FunctionExecutionAutoConfiguration
GemFirePropertiesAutoConfiguration
LoggingAutoConfiguration
PdxSerializationAutoConfiguration
PeerSecurityAutoConfiguration
RegionTemplateAutoConfiguration
RepositoriesAutoConfiguration
SpringSessionAutoConfiguration
SpringSessionAutoPropertiesConfiguration
SslAutoConfiguration

Switch from Apache Geode to Pivotal Cloud Cache (a.k.a. Pivotal GemFire)

First, understand that {pivotal-gemfire-website}[Pivotal GemFire] is being succeeded by {pivotal-cloudcache-website}[Pivotal Cloud Cache] (PCC). Therefore, all references to Pivotal GemFire (i.e. “gemfire”) also implies for Pivotal Cloud Cache (i.e. “cloudcache”) as well.

When it comes to Spring’s support, whether you are developing with Open Source Software (OSS) {apache-geode-website}[Apache Geode] or developing for Pivotal Cloud Cache, Spring has you covered.

At a strategic-level, this means:

From Open Source Software (e.g. Apache Geode) to Commercial (e.g. Pivotal Cloud Cache)
From Non-Managed Environments (e.g. Standalone, Externally Managed) to Managed Environments (e.g. Pivotal Platform)
With little to no code or configuration changes necessary. It just works!

You may also go back and migrate your Spring Boot applications away from Pivotal Platform when using the commercial software offering, Pivotal Cloud Cache, and switch back to Open Source Apache Geode running in a standalone, externally managed environment.

SBDG will not (ever) lock you in! It is your choice!

Technically, this means to go from Apache Geode to Pivotal Cloud Cache, you only need to change the SBDG dependency from:

To acquire the Pivotal Cloud Cache or Pivotal GemFire bits to use in your Spring Boot applications in place of Apache Geode, follow these instructions provided in the Pivotal GemFire documentation.

To go back, simple change spring-gemfire-starter back to spring-geode-starter. Done!

Spring Boot’s auto-configuration and convention over configuration approach tries to detect the runtime environment in order to handle infrastructure logistics so you will not have to. This is true inside or outside of a managed

It should just work without any code or configuration changes and if this is not the case, for whatever reason, then we will work to correct it, short of any feature differences between Pivotal Cloud Cache that cannot be accomplished with Apache Geode by itself.

To go back, simple change spring-gemfire-starter back to spring-geode-starter.

Done!

Spring Boot’s auto-configuration and convention over configuration approach tries to detect the runtime environment so that we can provide users with a consistent and reliable experience without all the hassle and issues that arise by switching environments. Switching environments is especially common as you migrate your Spring Boot applications from DEV to TEST, into STAGING, and finally, to PRODUCTION.

Of course, it will nearly always be easier to "run" Apache Geode as a "managed" service inside Pivotal Platform using Pivotal Cloud Cache than it will to manage an externally run Apache Geode cluster, especially if your Use Case requires maximum performance and high availability. We highly recommend this approach when and where possible, but it is still your choice.

Running an Apache Geode/Pivotal GemFire cluster using Spring Boot from your IDE

As described in [geode-clientcache-applications], it is possible to configure and run a small Apache Geode or Pivotal GemFire cluster from inside your IDE using Spring Boot. This is extremely helpful during development since it allows you to manually spin up, test and debug your applications quickly and easily.

Spring Boot for Apache Geode/Pivotal GemFire includes such a class:

Spring Boot application class used to configure and boostrap an Apache Geode/Pivotal GemFire server

@SpringBootApplication
@CacheServerApplication(name = "SpringBootApacheGeodeCacheServerApplication")
@SuppressWarnings("unused")
public class SpringBootApacheGeodeCacheServerApplication {

	public static void main(String[] args) {

		new SpringApplicationBuilder(SpringBootApacheGeodeCacheServerApplication.class)
			.web(WebApplicationType.NONE)
			.build()
			.run(args);
	}

	@Configuration
	@UseLocators
	@Profile("clustered")
	static class ClusteredConfiguration { }

	@Configuration
	@EnableLocator
	@EnableManager(start = true)
	@Profile("!clustered")
	static class LonerConfiguration { }

}

This class is a proper Spring Boot application that can be used to configure and bootstrap multiple Apache Geode or Pivotal GemFire servers and joining them together to form a small cluster simply by modifying the runtime configuration of this class ever so slightly.

Initially you will want to start a single, primary server with the embedded Locator and Manager service.

The Locator service enables members in the cluster to locate one another and allows new members to attempt to join the cluster as a peer. Additionally, the Locator service also allows clients to connect to the servers in the cluster. When the cache client’s Pool is configured to use Locators, then the Pool can intelligently route data requests directly to the server hosting the data (a.k.a. single-hop access), especially when the data is partitioned/sharded across servers in the cluster. Locator Pools include support for load balancing connections and handling automatic fail-over in the event of failed connections, among other things.

The Manager service enables you to connect to this server using Gfsh (the Apache Geode and Pivotal GemFire {apache-geode-docs}/tools_modules/gfsh/chapter_overview.html[shell tool]).

To start our primary server, create a run configuration in your IDE for the SpringBootApacheGeodeCacheServerApplication class with the following, recommended JRE command-line options:

Server 1 run profile configuration

-server -ea -Dspring.profiles.active=

Start the class. You should see similar output:

Server 1 output on startup

Now, let’s start some additional servers to scale-out our cluster.

To do so, you simply need to vary the name of the members we will add to our cluster as peers. Apache Geode and Pivotal GemFire require that the members in a cluster be named and the names of each member in the cluster be unique.

Additionally, since we are running multiple instances of our SpringBootApacheGeodeCacheServerApplication class, which also embeds a CacheServer instance enabling cache clients to connect, we need to be careful to vary our ports used by the embedded services.

Fortunately, we do not need to run another embedded Locator or Manager service (we only need 1 in this case), therefore, we can switch profiles from non-clusted to using the Spring "clustered" profile, which includes different configuration (the ClusterConfiguration class) to connect another server as a peer member in the cluster, which currently only has 1 member as shown in the list members Gfsh command output above.

To add another server, set the member name and the CacheServer port to a different number with the following run profile configuration:

Run profile configuration for server 2

-server -ea -Dspring.profiles.active=clustered -Dspring.data.gemfire.name=ServerTwo -Dspring.data.gemfire.cache.server.port=41414

Notice that we explicitly activated the "clustered" Spring profile, which enables the configuration provided in the nested ClusteredConfiguration class while disabling the LonerConfiguration class.

This ClusteredConfiguration class is also annotated with @UseLocators, which sets the GemFire/Geode locators property to "localhost[10334]". By default, it assumes the Locator process/service is running on "locahost", listening on the default Locator port of "10334". You can of course adjust your Locators endpoint if your Locators are running elsewhere in your network by using the "locators" attribute of the @UseLocators annotation.

It is common in production environments to run multiple Locators as a separate process. Running multiple Locators provides redundancy in case a Locator process fails. If all Locator processes in your network fail, don’t fret, your cluster will not go down. It simply means no other members will be able to join the cluster, allowing you to scale your cluster out, nor will any clients be able to connect. Simply just restart the Locators if this happens.

Additionally, we set the spring.data.gemfire.name property to "ServerTwo" adjusting the name of our member when it joins the cluster as a peer.

Finally, we set the spring.data.gemfire.cache.server.port to "41414" to vary the CacheServer port used by "ServerTwo". The default CacheServer port is "40404". If we had not set this property before starting "ServerTwo" we would have hit a java.net.BindException.

Both the spring.data.gemfire.name and spring.data.gemfire.cache.server.port properties are well-known properties used by SDG to dynamically configure GemFire/Geode using a Spring Boot application.properties file or Java System properties. You can find these properties in the Annotation Javadoc in SDG’s Annotation-based Configuration model. For instance, the spring.data.gemfire.cache.server.port property is documented {spring-data-geode-javadoc}/org/springframework/data/gemfire/config/annotation/CacheServerApplication.html#port--[here]. Most of the SDG annotations include corresponding properties that can be defined in application.properties and is explained in more detail {spring-data-geode-docs-html}/#bootstrap-annotation-config-properties[here].

After starting our second server, "ServerTwo", we should see similar output at the command-line, and in Gfsh, when we list members and describe member again:

Cache Server Information Server Bind : Server Port : 41414 Running : true Client Connections : 0 ---

When list members, we see "ServerTwo" and when we describe "ServerTwo", we see that its CacheServer port is appropriately set to "41414".

If we add 1 more server, "ServerThree" using the following run configuration:

Add server 3 to our cluster

-server -ea -Dspring.profiles.active=clustered -Dspring.data.gemfire.name=ServerThree -Dspring.data.gemfire.cache.server.port=42424

Again, we will see similar output at the command-line and in Gfsh:

Congratulations! You just started a small Apache Geode/Pivotal GemFire cluster, with 3 members, using Spring Boot from inside your IDE.

It is pretty simple to build and run a Spring Boot, Apache Geode/Pivotal GemFire, ClientCache application that connects to this cluster. Simply include and use Spring Boot for Apache Geode/Pivotal GemFire, ;-).

Testing

Spring Test for Apache Geode & Pivotal GemFire is a new, soon to be released and upcoming project to help developers write both Unit and Integration Tests when using either Apache Geode or Pivotal GemFire in a Spring context.

In fact, the entire test suite in Spring Boot for Apache Geode & Pivotal GemFire is based on this project.

All Spring projects integrating with either Apache Geode or Pivotal GemFire will use this new test framework for all their testing needs, making this new test framework for Apache Geode and Pivotal GemFire a proven and reliable solution for all your Apache Geode/Pivotal GemFire application testing needs when using Spring as well.

Later on, this reference guide will include and dedicate an entire chapter on testing.

Examples

The definitive source of truth on how to best use Spring Boot for Apache Geode & Pivotal GemFire (or Pivotal Cloud Cache (PCC)) is to refer to the Samples.

Refer to the Pivotal Cloud Cache (PCC), Pizza Store, Spring Boot application for an example of how to use Spring Boot for Pivotal GemFire (SBDG) in a ClientCache application interfacing with PCC.

Additionally, you may refer to the Temperature Service, Spring Boot application, which implements a Temperature Sensor and Monitoring, Internet of Things (IOT) example. The example uses SBDG to showcase Apache Geode CQ, Function Implementations/Executions and positions Apache Geode as a caching provider in Spring’s Cache Abstraction. It is a working, sophisticated and complete example, and is highly recommended as a good starting point for real-world use cases.

You may also refer to the boot-example from the Contact Application Reference Implementation (RI) for Spring Data for Apache Geode & Pivotal GemFire (SDG) as yet another example.
