Spring Fu 0.3.0 and beyond

I am happy to announce that Spring Fu 0.3.0 is available. As a reminder, Spring Fu is an incubator for Spring Boot programmatic configuration using DSLs in order to configure it explicitly with code in a declarative way, achieving great discoverability thanks to auto-complete.

JaFu is back!

This new milestone brings back JaFu (the Java DSL) in addition to KoFu (the Kotlin DSL). JaFu was removed in 0.1.0 because at that point, I had not the bandwidth to support both Java and Kotlin DSLs, and in term of API I was not sure that the Java variant was attractive enough to justify such effort, but I have changed my mind for various reasons:

  • I received a lot of requests to bring it back

  • Java as a language is moving faster

  • Getting more control on how configuration is applied is interesting for Java developers as well as Kotlin ones

  • Functional approach is naturally very efficient on the JVM and a good fit with GraalVM native images

  • 2 great new contributors have join the team: Audrey Neveu with a focus on KoFu and Arjen Poutsma with a focus on JaFu. Welcome to them!

What's new in Spring Data Elasticsearch 4.0

This article continues our blog post series on What’s new in Spring Data Neumann. Today’s installment explains New and Noteworthy in Spring Data Elasticsearch. This blog post was written by P.J. Meisch who maintains the Spring Data Elasticsearch module.

This release addresses more than 140 issues, with more than 30 bugs fixed.

Spring Data Elasticsearch now uses Elasticsearch 7, 7.6.2 in particular. Elasticsearch clusters running on 6.x versions are not supported anymore. The ElasticsearchTemplate class is deprecated as it uses the TransportClient to access Elasticsearch, which itself is deprecated since Elasticsearch version 7.+ Users should switch to ElasticsearchRestTemplate or ReactiveElasticsearchTemplate.

Getting Started With RSocket: Testing Spring Boot Responders

Reading time: about 6 minutes
Coding time: about 15 minutes

If you’ve been following this series, by now, you’ll have built a Spring Boot prototype that illustrates many of the features present in RSocket. This code isn’t production code, though; it’s a prototype, a stepping stone on your RSocket journey. For production code, I’d expect all the usual quality assurance and testing rules to apply. So in this exercise, I’ll show you how to write integration tests for RSocket responders, so you can get one step closer to production.
