Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in Antwerp, Belgium for the amazing Devoxx (Belgium) event. I'm co-presenting with my friends Matt Raible and Mark Heckler on progressive web applications and reactive Spring. I'll be joined by a lot of Pivotal and Spring teammates here so make sure to check the schedule.

Later this week I'll be doing a joint webinar - Grails for the Spring Boot Developer - with Grails co-founder Jeff Scott Brown.

Then, it's off to Casablanca, Morocco, for the Devoxx MA event.

If you're at either event, don't hesitate to say hi…

Previously, Spring Security used the ServerWebExchange.getPrincipal() as the source of truth for who was authenticated. The authenticated user was copied to Reactor’s Context to support method security which used the Reactor Context as it’s source of…

On behalf of the community I’m pleased to announce the release of Spring Session 2.0.0.RC1. This release puts some final touches to preparing for 2.0.0.RELEASE. You can find the complete changelog in github, with the highlights below:

On behalf of the Spring Integration team I am pleased to announce that the Release Candidate 1 for the Spring Integration 5.0 version (5.0.0.RC1) is now available.

It can be downloaded from the Milestone Repository:

repositories {
    maven { url 'http://repo.spring.io/libs-milestone' }
}

compile "org.springframework.integration:spring-integration-core:5.0.0.RC1"

20 JIRAs (and some GitHub issues) are included in this release, together with bug fixes and a number of new features. Some highlights of features in the RC1, since the previously announced Milestone 7:

• The components populated by the Java DSL parser are now registered as BeanDefinitions in the application context, thanks to newly introduced in the Spring Framework 5.0 Supplier-based programmatic bean registration. This approach helps us to avoid some boilerplate code for singletons registration and initialization. In addition this BeanDefinition registration may be useful in some use-case to select particular components in the application context. In fact, exactly that is used in the Spring Cloud Function project for java.util.function.* beans scanning.

• The IntegrationFlows.from(Class<?> serviceInterface) has now overloaded version with an additional beanName argument. This becomes exactly the bean name for a generates gateway proxy overriding the [flowId].gateway value:

  @Bean public IntegrationFlow uppercaseFlow() { return IntegrationFlows.from(MessageFunction.class, "uppercase") .<String, String>transform(String::toUpperCase) .get(); }

  …

On behalf of the Spring Cloud team, it is my pleasure to announce a new milestone release of Spring Cloud Pipelines - 1.0.0.M7.
