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
• In last week's episode of a Bootiful Podcast, I talk to JAXB contributor, COM4j, Jenkins and Launchable founder Kohsuke Kawaguchi
• Migrating to Spring Data JDBC 2.0
• Spring Cloud Data Flow 2.5.1 Released
• What can Spring do? Find out
• An Overview of Apache Tomcat
• I'll be speaking at JPoint later this summer along with Cay Horstmann and James Gosling.
• didipostman/GenomeSequencing: Spring Batch as genome sequencing solution
• Senior Software Engineer - Spring, OSS Observability (Remote US or EMEA) in Multiple Locations | main

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?

Integration…

Hi Spring fans! In today's installment Josh Long (@starbuxman) talks to Kohsuke Kawaguchi (@kohsukekawa) who needs no introduction - one of the original contributors to JAXB, COM4J, and a host of all sorts of other projects, and is the founder and CEO of Launchable. Oh, did I mention he also created Jenkins, the most popular CI server ever? Enjoy!

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.

TL;DR

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…

Spring Cloud Data Flow team is pleased to announce the release of 2.5.1.

This release includes some bug fixes with the some of the notable changes as follows:

• DeploymentProperties parsing fixes.
• Removed behaviour for server to attempt to contact dockerhub during a start.
• Fixes to dataflow client to re-authorize when oauth client credentials are used.
• Liveness and readiness probe changes to kubernetes deployment files.
• Upgrades to Spring Boot 2.2.7 and Spring Cloud Hoxton.SR4. New dependencies from these fixed an issue in Spring Data Rest which caused repository mappings DATAREST-1502 to stop working and effectively caused UI and Skipper to start behaving erratically in Data Flow 2.5.0.

On behalf of the Spring, Apache Geode and VMWare GemFire communities, it is my pleasure to announce the release of Spring Session for Apache Geode and VMware GemFire (SSDG) 2.1.10.RELEASE, 2.2.4.RELEASE and 2.3.0.RELEASE.

All bits are available in Maven Central.

SSDG 2.1.10.RELEASE is aligned with Spring Boot 2.1.14.RELEASE and can be included by declaring a dependency on org.springframework.geode:spring-geode-starter-session:1.1.7.RELEASE.

SSDG 2.2.4.RELEASE is aligned with Spring Boot 2.2.7.RELEASE and can be included by declaring a dependency on org.springframework.geode:spring-geode-starter-session:1.2.7.RELEASE…

On behalf of the Spring, Apache Geode and VMware GemFire communities, it is my pleasure to announce the release of Spring Boot for Apache Geode & VMware GemFire (SBDG) 1.1.7.RELEASE, 1.2.7.RELEASE and 1.3.0.RC1.

All bits are available in Maven Central with the exception of 1.3.0.RC1, which is available in Spring’s Milestone Repository.

SBDG 1.1.7.RELEASE builds on Spring Boot 2.1.14.RELEASE. SBDG 1.2.7.RELEASE builds on Spring Boot 2.2.7.RELEASE and SBDG 1.3.0.RC1 builds on Spring Boot 2.3.0.RC1.

The easiest way to get started building Spring Boot applications with Apache Geode is by using Spring Initializer at start.spring.io either with Spring Boot 2.2.7 or with Spring Boot 2.3.0…

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.

• R2DBC support (see this Spring Tips installment on using R2DBC
• 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.
…

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:

• Spring Data JDBC 2.0 (was 1.1 before)
  Here’s the link to the post that explains migration from Spring Data JDBC 1.1 to 2.0.

• Spring Data MongoDB 3.0 (was 2.2 before)

• Spring Data for Apache Cassandra 3.0 (was 2.2 before)

• Spring Data Couchbase 4.0 (was 3.2 before)

• Spring Data Elasticsearch 4.0 (was 3.2 before)
