The Spring Blog

We are pleased to announce that Spring Batch 4.1.1, 4.0.2, and 3.0.10 are available from repo.spring.io and Maven Central.

These releases contain security and bug fixes as well as dependencies updates. We recommend users upgrade to one of these versions. Please find the change log for each version in the following links: 4.1.1 | 4.0.2 | 3.0.10

As we announced earlier, please note that v3.0.10 is the last planned release for the 3.x line, so we highly recommend users to upgrade to the latest possible version.

On behalf of the Spring Data team, I’d like to announce the availability of the Lovelace SR4, Kay SR13, and Ingalls SR18 maintenance releases. Today’s releases pick up the latest Spring Framework maintenance releases: 5.1.4, 5.0.12, and 4.3.22, respectively. The upcoming Spring Boot releases (2.1.2, 2.0.8, and 1.5.19) are going to pick up Lovelace SR4, Kay SR13, and Ingalls SR18, for your convenience.

The service releases ship with bug fixes and dependency upgrades and address over 170 tickets in total. You can find the complete list of tickets by following the links below:

This is part 3 of a 6 part series, with new posts Mondays and Thursdays, introducing Microsoft Azure for Spring developers. I couldn’t have put this together without input from Microsoft’s Asir Vedamuthu Selvasingh, Yitao Dong, Bruno Borges, Brian Benz and Theresa Nguyen. You can find the code for this series on Github. Hit me up on Twitter (@starbuxman) as you’re reading the installments with any feedback or questions. You can also learn more about Microsoft Azure in my Spring Tips (@SpringTipsLive) installment, Bootiful Azure

Spring Cloud Stream has recently added a feature to compose a function definition into an existing Spring Cloud Stream application. In this blog, we’ll see how Spring Cloud Data Flow
makes use of this feature to compose functions in Streaming pipelines.

What’s different about it?

In Spring Cloud Data Flow, streaming data pipelines are comprised of Spring Cloud Stream applications. A developer can pick and choose the out-of-the-box streaming applications, which cover many common use cases. A developer can also extend these out-of-the-box applications or create custom applications by using Spring Cloud Stream framework.

Dear Spring community,

It is my pleasure to announce that Spring Framework 5.1.4, 5.0.12 and 4.3.22 are available from repo.spring.io as well as Maven Central now.

5.1.4 is a significant refinement release, addressing several regressions and gaps that have been identified since 5.1 GA, coming as an immediate upgrade for all 5.1.x users.

Please note that 5.0.12 is the last planned 5.0.x release, with 5.0 approaching its EOL in March 2019. All 5.0.x users are encouraged to upgrade to 5.1.4+ for further fixes and refinements.

Hi Spring fans! In this installment of Spring Tips we look at how to use the Apache 2 licensed Flowable BPMN 2 workflow engine with Spring.

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I’ve just concluded the second of my two online trainings, one on Monday on Reactive Spring, and another today on using Spring Boot in Kotlin. This week I’ll be in Montreal, Canada for an appearance at the Montreal JUG and at Dawscon. I’d love to see you at both events! Come out and say “Hi!” or “Bonjour!”
