AbstractMessageBrokerConfiguration (Spring Framework 4.2.3.RELEASE API)

java.lang.Object
- org.springframework.messaging.simp.config.AbstractMessageBrokerConfiguration

All Implemented Interfaces:

Aware, ApplicationContextAware

Direct Known Subclasses:

WebSocketMessageBrokerConfigurationSupport
```
public abstract class AbstractMessageBrokerConfiguration
extends Object
implements ApplicationContextAware
```
Provides essential configuration for handling messages with simple messaging protocols such as STOMP.
clientInboundChannel() and clientOutboundChannel() deliver messages to and from remote clients to several message handlers such as
while brokerChannel() delivers messages from within the application to the the respective message handlers. brokerMessagingTemplate() can be injected into any application component to send messages.
Subclasses are responsible for the part of the configuration that feed messages to and from the client inbound/outbound channels (e.g. STOMP over WebSocket).

protected AbstractMessageBrokerConfiguration()
```
    Protected constructor.
- Method Detail
  - setApplicationContext
```
public void setApplicationContext(ApplicationContext applicationContext)
```
    Description copied from interface: ApplicationContextAware
    
    Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.
    Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.
    
    Specified by:
    
    setApplicationContext in interface ApplicationContextAware
    
    Parameters:
    
    applicationContext - the ApplicationContext object to be used by this object

@Deprecated
protected UserSessionRegistry userSessionRegistry()
```
    Deprecated.
    
    As of 4.2, UserSessionRegistry is deprecated in favor of SimpUserRegistry exposing information about all connected users. The MultiServerUserRegistry implementation in combination with UserRegistryMessageHandler can be used to share user registries across multiple servers.
  - simpValidator
```
protected Validator simpValidator()
```
    Return a Validators instance for validating @Payload method arguments.
    In order, this method tries to get a Validator instance:
    - delegating to getValidator() first
    - if none returned, getting an existing instance with its well-known name "mvcValidator", created by an MVC configuration
    - if none returned, checking the classpath for the presence of a JSR-303 implementation before creating a OptionalValidatorFactoryBean
    - returning a no-op Validator instance
  - getValidator
```
public Validator getValidator()
```
    Override this method to provide a custom Validator.
