What’s New in Spring Session 2.0

You can find highlights of what’s new in the What’s New 2.0 section of the reference. For details refer to the changelog links above.

Requirements

This release moves to Java 8 and Spring Framework 5.0 as baseline requirements. Entire codebase is based on Java 8 source code level now.

Spring WebFlux Support

Introduction of reactive programming model in Spring Framework 5.0 has been one of the biggest stories in 2017, and we’re happy to bring the support for managing Spring WebFlux’s WebSession with Redis ReactiveSessionRepository.

In a familiar Spring Session fashion, enabling Redis backed WebSession support is as simple as the following code snippet:

@EnableRedisWebSession
public class WebSessionConfig {

    @Bean
    public LettuceConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory();
    }

}

Spring Boot users will be happy to learn that auto-configuration support for reactive Spring Session is already available since the 2.0.0.M6 milestone release.

Spring Session Modules

The new release bring some major changes to project’s modules, as we have split Spring Session into modules based upon the repository implementation. You will find:

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-core</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-hazelcast</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-jdbc</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>

As a part of this change, we have removed some of the Spring Session implementations from the main repository. We now have sub projects for Spring Session Data Geode (GemFire) and Spring Session Data MongoDB. You will find:

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-gemfire</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-geode</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-mongodb</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>

The goal is to allow the core Spring Session team to focus on delivering new features rather than needing to know the ins and outs of every data store. This will allow development of other modules to be done without the overhead of reviews from the core Spring Session team.
