Simplified WebFlux Configuration

Configuring Spring Session for WebFlux is simplified to be:

@Configuration
@EnableSpringWebSession
public class HelloWebfluxSessionConfig {

  @Bean
  public MapReactorSessionRepository reactorSessionRepository() {
    return new MapReactorSessionRepository(new ConcurrentHashMap<>());
  }
}

You can also switch the strategy for resolving session id’s by simply adding a WebSessionIdResolver Bean. For example, to switch from using cookies to resolve the session id to using headers, you can use Spring Framework’s new HeaderWebSessionIdResolver…

This milestone provides a host of minor tweaks and enhancements along with three major changes:

• A new Actuator endpoint infrastructure
• An overhaul of security
• Micrometer metrics support

For a complete list of changes, and upgrade instructions, see the Spring Boot 2.0.0.M4 Release Notes on the WIKI. We are a bit behind with regards to updating the reference documentation, so please consider using the snapshot version…

Problem Statement

Until Spring Boot 1.x, the default auto-configuration secured all of the application endpoints using basic authentication. If actuator was on the classpath, there was a separate security configuration that applied to the actuator endpoints. The way these two auto-configurations would turn on and off was completely independent. Because of this, users wanting to provide custom security found themselves fighting ordering issues with WebSecurityConfigurerAdapters.

Additionally, for actuator endpoints, the effects of the management.security.enabled…

Kafka Streams for Apache Kafka

This release targets the promotion of Kafka Streams for Apache Kafka support as a top-level project in the Apache Kafka binder implementation. With Kafka Streams for Apache Kafka positioned as a first-class citizen, developers can now build Spring Cloud Stream applications by…

It is available for download from the Milestone Repository:

repositories {
    maven { url 'http://repo.spring.io/libs-milestone' }
}
compile "org.springframework.integration:spring-integration-core:5.0.0.M7"

21 JIRAs (and some GitHub issues) made into this release, including bug fixes and a number of new features. Some highlights of features in the M7, since the previously announced Milestone 6:

• Reactive WebFlux Channel Adapters has been extracted to the separate spring-integration-webflux module to distinguish Servlet-based MVC configuration from the Reactive foundation.

• The EmbeddedJsonHeadersMessageMapper is introduced to allow embedding message headers together with the payload into packages for target protocols which doesn’t support headers natively, for example TCP/IP, MQTT, AWS Kinesis and Apache Kafka before version 0.11.x.

• The java.util.function.Supplier can now act as a MessageSource:

As discussed in the 1.3.0.M2 announcement, we are concurrently releasing 1.3 with 2.0, where 1.3 contains a subset of the 2.0 features, supporting the Kafka 0.11.x.x client, while still supporting Spring Framework 4.3. As such, the 1.3.0.RC1 release candidate is also available.

They are available for download from the Milestone Repository:

repositories {
    maven { url 'http://repo.spring.io/libs-milestone' }
}
compile "org.springframework.kafka:spring-kafka:2.0.0.RC1"

Since the previous announcement, the following is a summary…

This release adds some minor fixes/improvements since the final milestone Milestone 5.

Thanks to all the community member for their feedback and contributions!

The GA release will follow shortly after the Spring Framework 5.0 GA release in September.

For a complete list of changes in 2.0, see What’s New in the reference manual.

Maintenance releases 1.7.4 and 1.6.11 are also available now.

Spring Boot 1.5.7 includes 51 fixes, improvements and dependency updates. Thanks to all that have contributed with issue reports and pull requests.

What's next?

Spring Framework 5.0 RC4 has just been released and other Spring projects should follow. Spring Boot 2.0 M4 is just around the corner and this will be a nice way to test the last release candidate of Spring Framework before GA. If you want to take an early look at Spring Boot 2, and we’d love to hear your feedback if you do, please go to start.spring.io and select Spring Boot 2.0.0.BUILD-SNAPSHOT…
