On behalf of the community, I am happy to announce the general availability of the Spring Cloud Stream Chelsea release train. For this release train, the first general availability release is Chelsea.SR1, which fixes a number of issues over Chelsea.RELEASE (all within the scope of the metrics export feature). Chelsea.SR1 is also included as part of Spring Cloud Dalston.RELEASE.

The new release is available in Maven Central, and a detailed description of its features can be found in the reference documentation. For information about artifacts and most recent changes, please consult the release…

On behalf of the Spring Data team, I'd like to announce the availability of the second milestone of the release train Kay. The release is an important step towards a second generation of Spring Data.

We've upgraded the majority of the codebase to Java 8, now also embracing e.g. Optional in method signatures. This mostly affects internal SPIs but also leaks into user code, especially in CrudRepository. The support for reactive Spring Data repositories has been extended to Couchbase (Thanks, Subhashni!), the Redis module has a reactive template API now. The release also ships support for IsEmpty and IsNotEmpty for derived queries and implementaitons of those for MongoDB and JPA. The aggregation framework in MongoDB now also supports…

On behalf of the community, it's my pleasure to announce the general availability of Spring Vault 1.0 – the very first GA release of Spring Vault after almost a year of development.

The artifacts are available from Maven Central and Bintray.

<dependency>
  <groupId>org.springframework.vault</groupId>
  <artifactId>spring-vault-core</artifactId>

• Pluggable application authentication via AppRole, AWS-EC2, client certificates, Cubbyhole (wrapped tokens) and static tokens.
• Support for renewable @VaultPropertySource with credentials rotation.
• Lifecycle-aware session management with token renewal and re-login after terminal token expiry.

Hi Spring fans! We've now finished two seasons - 11 episodes and a recap post each - of Spring Tips. I'm going to take a little while to dream up some more content and, before you know it, we'll be back at it again! I'm always interested in hearing proposed topics so if you have some, please, by all means, shout it out loud to me on Twitter (@starbuxman) or by email ([email protected]).

The motivations for me in doing these Spring Tips are:

• revisit traditional topics in light of Spring Boot and
• highlight parts of the amazing Spring ecosystem that, for one reason or another, don't get enough attention.

Welcome to another installation of This Week in Spring!

• Spring Integration ninja Artem Bilan just announced Spring Integration 5.0.M3. The new release includes an integration test framework, speed improvements, support for the Spring 5 reactive WebClient, retroactive restoration of file trees when using the (S)FTP and AWS S3 inbound adapters, a smarter SOAP web-services gateway, and much more.
• Spring Integration lead Gary Russell just announced Spring for Apache Kafka 1.2.0 and 1.1.4

We are pleased to announce that these maintenance releases of Spring for Apache Kafka are now available, 1.2.0.RELEASE and 1.1.4.RELEASE.

These versions include several bug fixes and improvements, as well as introduce support for KStreams.

They are functionally equivalent; the 1.2.0.RELEASE is based on the 0.10.2.0 kafka-clients jar and 1.1.4.RELEASE can be used with 0.10.0.x and 0.10.1.x.

While 1.1.4.RELEASE will work at runtime with a 0.10.2.x client library, some breaking changes in the embedded kafka API means that the embedded kafka Junit @Rule in spring-kafka-test will not work and 1.2.…

One of the main themes of Spring Boot 2.0 M1 is a range of significant improvements to its Gradle plugin. Many of those improvements have just been merged and are available in the latest Spring Boot snapshots. There's a few weeks until Spring Boot 2.0.0.M1 will be released at the beginning of May and we'd love to hear your early feedback on the new plugin before then.

You can read more about the plugin's capabilities in its reference and API documentation.

Trying the new plugin

The new plugin requires Gradle 3.4 or later. Like the rest of Spring Boot, snapshots are published to https://repo.spring.io/libs-snapshot. The easiest way to use a snapshot is to create a new Gradle project on start.spring.io…
