What's new in Spring Data Elasticsearch 4.0

Engineering | Mark Paluch | May 27, 2020 | ...

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

This Week in Spring - May 26th, 2020

Hi, Spring fans! Welcome to another installment of This Week in Spring! How're things? My family and I spent the Memorial Day holiday weekend mostly playing video games and trying random new restaurants for delivery. Now, it's back to the grind and there are a ton of things to look at so let's get to it!

Getting Started With RSocket: Testing Spring Boot Responders

Engineering | Ben Wilcock | May 24, 2020 | ...

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.

But first, what do I mean by integration testing?


Migrating to Spring Data JDBC 2.0

Engineering | Jens Schauder | May 20, 2020 | ...

With Spring Data JDBC 2.0, we had to introduce some breaking changes. The goal of this article is to help in the migration process.


  1. Use the default letter casing for custom column and table names or quote the names for table generation exactly as used in the annotations.

  2. Use AbstractJdbcConfiguration for custom configuration of the application context.

  3. Register a Dialect if necessary.

  4. Review event-handling code and ensure the data you try to use is not null.

Quoting of Identifiers

Spring Data JDBC 1.x uses table and column names mostly without changing them. This causes…

Hi, Spring fans! Welcome to another installment of This Week in Spring! What a wonderful, bootiful week it's been! This last week saw the long-awaited release of Spring Boot 2.3.0!

There are a lot of wonderful features in this release including, but not limited to, Java 14 support, Docker image generation, graceful shutdown, liveliness probes, upgrades to Spring Data Neumann, and so much more. Here are some resources on some of those features. And, also, check out the blog.

  • Docker container image support. See this blog on Docker image generation
  • Java 14 support. See this Spring Tips installment on Java 14
  • This is also the version to use if you want to consume the Graal Native Image builder feature. Here's a Spring Tips video on that, too.

What's new in Spring Data (Klara Dan von) Neumann?

Engineering | Christoph Strobl | May 18, 2020 | ...

Spring Data Neumann is the first release to follow the new six-month cadence. The reduced timeframe lets us deliver new features more often, which is key in enabling you to move faster. The release itself ships with a bunch of new stuff and includes important (potentially breaking) upgrades of several store.

Major Version Upgrades

Several store modules, as listed below, required a major version bump due to potentially breaking changes in either their exposed API or their drivers:
