Getting Spring Security

This section describes how to get the Spring Security binaries. See Source Code for how to obtain the source code.

Release Numbering

Spring Security versions are formatted as MAJOR.MINOR.PATCH such that:

  • MAJOR versions may contain breaking changes. Typically, these are done to provide improved security to match modern security practices.

  • MINOR versions contain enhancements but are considered passive updates.

  • PATCH level should be perfectly compatible, forwards and backwards, with the possible exception of changes that fix bugs.

Usage with Maven

As most open source projects, Spring Security deploys its dependencies as Maven artifacts. The topics in this section describe how to consume Spring Security when using Maven.

Spring Boot with Maven

Spring Boot provides a spring-boot-starter-security starter that aggregates Spring Security-related dependencies. The simplest and preferred way to use the starter is to use Spring Initializr by using an IDE integration in (Eclipse or IntelliJ, NetBeans) or through start.spring.io. Alternatively, you can manually add the starter, as the following example shows:

pom.xml
<dependencies>
	<!-- ... other dependency elements ... -->
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-security</artifactId>
	</dependency>
</dependencies>

Since Spring Boot provides a Maven BOM to manage dependency versions, you do not need to specify a version. If you wish to override the Spring Security version, you can do so by providing a Maven property:

pom.xml
<properties>
	<!-- ... -->
	<spring-security.version>6.3.6-SNAPSHOT</spring-security.version>
</properties>

Since Spring Security makes breaking changes only in major releases, you can safely use a newer version of Spring Security with Spring Boot. However, at times, you may need to update the version of Spring Framework as well. You can do so by adding a Maven property:

pom.xml
<properties>
	<!-- ... -->
	<spring.version>6.1.15</spring.version>
</properties>

If you use additional features (such as LDAP, OAuth 2, and others), you need to also include the appropriate Project Modules and Dependencies.

Maven Without Spring Boot

When you use Spring Security without Spring Boot, the preferred way is to use Spring Security’s BOM to ensure that a consistent version of Spring Security is used throughout the entire project. The following example shows how to do so:

pom.xml
<dependencyManagement>
	<dependencies>
		<!-- ... other dependency elements ... -->
		<dependency>
			<groupId>org.springframework.security</groupId>
			<artifactId>spring-security-bom</artifactId>
			<version>{spring-security-version}</version>
			<type>pom</type>
			<scope>import</scope>
		</dependency>
	</dependencies>
</dependencyManagement>

A minimal Spring Security Maven set of dependencies typically looks like the following example:

pom.xml
<dependencies>
	<!-- ... other dependency elements ... -->
	<dependency>
		<groupId>org.springframework.security</groupId>
		<artifactId>spring-security-web</artifactId>
	</dependency>
	<dependency>
		<groupId>org.springframework.security</groupId>
		<artifactId>spring-security-config</artifactId>
	</dependency>
</dependencies>

If you use additional features (such as LDAP, OAuth 2, and others), you need to also include the appropriate Project Modules and Dependencies.

Spring Security builds against Spring Framework 6.1.15 but should generally work with any newer version of Spring Framework 5.x. Many users are likely to run afoul of the fact that Spring Security’s transitive dependencies resolve Spring Framework 6.1.15, which can cause strange classpath problems. The easiest way to resolve this is to use the spring-framework-bom within the <dependencyManagement> section of your pom.xml:

pom.xml
<dependencyManagement>
	<dependencies>
		<!-- ... other dependency elements ... -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-framework-bom</artifactId>
			<version>6.1.15</version>
			<type>pom</type>
			<scope>import</scope>
		</dependency>
	</dependencies>
</dependencyManagement>

The preceding example ensures that all the transitive dependencies of Spring Security use the Spring 6.1.15 modules.

This approach uses Maven’s “bill of materials” (BOM) concept and is only available in Maven 2.0.9+. For additional details about how dependencies are resolved, see Maven’s Introduction to the Dependency Mechanism documentation.

Maven Repositories

All GA releases (that is, versions ending in .RELEASE) are deployed to Maven Central, so you need not declare additional Maven repositories in your pom.

If you use a SNAPSHOT version, you need to ensure that you have the Spring Snapshot repository defined:

pom.xml
<repositories>
	<!-- ... possibly other repository elements ... -->
	<repository>
		<id>spring-snapshot</id>
		<name>Spring Snapshot Repository</name>
		<url>https://repo.spring.io/snapshot</url>
	</repository>
</repositories>

If you use a milestone or release candidate version, you need to ensure that you have the Spring Milestone repository defined, as the following example shows:

pom.xml
<repositories>
	<!-- ... possibly other repository elements ... -->
	<repository>
		<id>spring-milestone</id>
		<name>Spring Milestone Repository</name>
		<url>https://repo.spring.io/milestone</url>
	</repository>
</repositories>

Gradle

As most open source projects, Spring Security deploys its dependencies as Maven artifacts, which allows for first-class Gradle support. The following topics describe how to consume Spring Security when using Gradle.

Spring Boot with Gradle

Spring Boot provides a spring-boot-starter-security starter that aggregates Spring Security related dependencies. The simplest and preferred method to use the starter is to use Spring Initializr by using an IDE integration in (Eclipse or IntelliJ, NetBeans) or through start.spring.io.

Alternatively, you can manually add the starter:

build.gradle
dependencies {
	implementation "org.springframework.boot:spring-boot-starter-security"
}

Since Spring Boot provides a Maven BOM to manage dependency versions, you need not specify a version. If you wish to override the Spring Security version, you can do so by providing a Gradle property:

build.gradle
ext['spring-security.version']='6.3.6-SNAPSHOT'

Since Spring Security makes breaking changes only in major releases, you can safely use a newer version of Spring Security with Spring Boot. However, at times, you may need to update the version of Spring Framework as well. You can do so by adding a Gradle property:

build.gradle
ext['spring.version']='6.1.15'

If you use additional features (such as LDAP, OAuth 2, and others), you need to also include the appropriate Project Modules and Dependencies.

Gradle Without Spring Boot

When you use Spring Security without Spring Boot, the preferred way is to use Spring Security’s BOM to ensure a consistent version of Spring Security is used throughout the entire project. You can do so by using the Dependency Management Plugin:

build.gradle
plugins {
	id "io.spring.dependency-management" version "1.0.6.RELEASE"
}

dependencyManagement {
	imports {
		mavenBom 'org.springframework.security:spring-security-bom:6.3.6-SNAPSHOT'
	}
}

A minimal Spring Security Maven set of dependencies typically looks like the following:

build.gradle
dependencies {
	implementation "org.springframework.security:spring-security-web"
	implementation "org.springframework.security:spring-security-config"
}

If you use additional features (such as LDAP, OAuth 2, and others), you need to also include the appropriate Project Modules and Dependencies.

Spring Security builds against Spring Framework 6.1.15 but should generally work with any newer version of Spring Framework 5.x. Many users are likely to run afoul of the fact that Spring Security’s transitive dependencies resolve Spring Framework 6.1.15, which can cause strange classpath problems. The easiest way to resolve this is to use the spring-framework-bom within your dependencyManagement section of your build.gradle. You can do so by using the Dependency Management Plugin:

build.gradle
plugins {
	id "io.spring.dependency-management" version "1.0.6.RELEASE"
}

dependencyManagement {
	imports {
		mavenBom 'org.springframework:spring-framework-bom:6.1.15'
	}
}

The preceding example ensures that all the transitive dependencies of Spring Security use the Spring 6.1.15 modules.

Gradle Repositories

All GA releases (that is, versions ending in .RELEASE) are deployed to Maven Central, so using the mavenCentral() repository is sufficient for GA releases. The following example shows how to do so:

build.gradle
repositories {
	mavenCentral()
}

If you use a SNAPSHOT version, you need to ensure that you have the Spring Snapshot repository defined:

build.gradle
repositories {
	maven { url 'https://repo.spring.io/snapshot' }
}

If you use a milestone or release candidate version, you need to ensure that you have the Spring Milestone repository defined:

build.gradle
repositories {
	maven { url 'https://repo.spring.io/milestone' }
}
