Spring Integration 4.1 was just released and it includes a lot of great new features! One of my favorites? Smart integration with the Spring 4 WebSocket support. Now you can compose a integration flow whose final destination is a WebSocket client. There is also support for acting as the client to a WebSocket service.

In order to compile it, you will need Java 8 (we make heavy use of lambdas here) and the following Maven dependencies:

• groupId:org.springframework.integration, artifactId:spring-integration-java-dsl, version: 1.0.0.RC1.
• groupId:org.springframework.integration, artifactId:spring-integration-websocket, version: 4.1.0.RELEASE.
• groupId:org.springframework.boot, artifactId:spring-boot-starter-websocket, version: 1.2.0.RC1.

We are pleased to announce the second milestone release of Spring for Apache Hadoop 2.1. The release is now available in the Spring IO repository

There are lots of version upgrades for the 2.1.0.M2 release: Spring Framework 4.1.2, Spring Boot 1.2.0.RC1 and more. See the full changelog for more details.

We updated the Kite SDK dataset support to 0.17.0 and this means there are some changes to the API. The use of a namespace in addition to the basePath is now mandatory. The DatasetTemplate now also uses ViewCallbacks instead of a partition expression for querying the data.

Beginning with the…

Speaker: Stephane Maldini, Pivotal

What is the role of asynchronous, non-blocking style-communication in microservices? Join Stephane Maldini for a revealing look at why reactive components are so important in an eventually-consistent approach like microservice architecture. When services own their data and are completely independent, having a (reactive) abstraction layer can perform a variety of roles. Being able to parallelize resources a microservice owns is an important technique. Another might be as an event bus, pulling state data from various micro services dynamically, checking against the cached, fairly up-to-date local copy. While a microservice has “all” the data it needs from other services to respond to a request, this data is not necessarily up-to-date—an important constraint to be prepared to accept. Stephane will also discuss other async use cases outside of microservices and how www.reactive-streams.org protocol support allows levels of portability across vendor implementations.

Welcome to another installment of This Week in Spring! This week I'm back in Silicon Valley, talking to developers at a handful of large technology-driven companies about taking their first steps with a cloud-native architecture. Interesting feedback, as ever! This week I'll be doing a meetup here in the bay area on building Bootiful microservices with Spring Cloud. Next week, I look forward to seeing people at Java2Days in Sofia, Bulgaria! C'ya there!

1. Spring Integration lead Gary Russell has just announced Spring Integration 4.1.0 and Spring AMQP 1.4.0 final are now available!

• Spring Security OAuth 2.0.4.RELEASE Available Now. The new release contains a few nice additions and a few bug fixes, making it a recommended, easy upgrade.
• Spring lead Juergen Hoeller just announced the availability of Spring Framework 4.1.2, accompanied by 4.0.8 and 3.2.12 maintenance releases.
• I'll be doing a webinar with ZeroTurnaround's Adam Koblentz introducing how to use Spring (and Spring Boot in particular) and JRebel 6…

Spring Boot 1.1.9 has been released and is available now from repo.spring.io and Maven Central.

This maintenance release includes a number of fixes and third-party dependency updates.

This release also upgrades to the latest Spring Framework, which includes an important security patch; as such it is highly recommended that all Spring Boot users upgrade.
