Spring Blog

speaker: Josh Long (@starbuxman)

Hi, Spring fans! Welcome to another installment of Spring tips! in this installment, we’re going to look at something that’s rather foundational, and something that I wish I’d addressed earlier: configuration. And no, I don’t mean functional configuration or java configuration or anything like that, I’m talking about the string values that inform how your code executes. the stuff that you put in application.properites. that configuration.

All configuration in Spring emanates from the Spring Environment abstraction. The Environment is sort of like a dictionary - a map with keys and values. Environment is just an interface through which we can ask questions about, you know, the Environment. The abstraction lives in Spring Framework and was introduced in Spring 3, more than a decade ago. up until that point, there was a focused mechanism to allow integration of configuration called property placeholder resolution. This environment mechanism and the constellation of classes around that interface more than supersede that old support. if you find a blog still using those types, may I suggest you move on to newer and greener pastures? :)

Dear Spring Community,

I am happy to announce the 4.6.1 release of the Spring Tools 4 for Eclipse, Visual Studio Code, and Theia.

Highlights from this release include:

• (Spring Boot) improvement: Spring yaml validation doesn’t understand the “<<:” syntax (#440)
• (Spring Boot) improvement: YAML Property completion: Superclass properties not detected in case of List or Map (#449)
• (Spring Boot) improvement: improved performance for content-assist for Spring XML config files
• (Spring Boot) bugfix: Quick Fix for unknown properties broken (#442)
• (Eclipse) improvement: early access builds on Eclipse 2020-06 milestone builds available
• (Eclipse) improvement: reduced timeout for ls-based content-assist for the Java Editor, so broken or slow language server behavior should not damage JDT content-assist experience anymore
• (Eclipse) improvement: vastly reduced communication traffic around classpath changes between Eclipse and the Spring Boot language server
• (Eclipse) improvement: async retrieval of properties of remote apps in boot dashboard to avoid UI freezes or delays
• (Eclipse) bugfix: org.eclipse.mylyn.wikitext.markdown required to update to 4.6.0 (#429)
• (Eclipse) bugfix: remote targets in boot dashboard always re-appeared after deleting them
• (Eclipse) bugfix: errors being logged at language server startup, related LSP4E rename handler
• (VSCode): Visual Studio Code extensions now available from the https://open-vsx.org marketplace

We are pleased to announce the release of Spring Cloud App Broker 1.0.5. This release includes the following fixes and improvements:

• Upgrade to Spring Boot 2.1.13.RELEASE
• Allow a ServiceInstanceService bean to be provided by a consuming application
• Correct an issue where the backing app environment was not being updated when the service instance was upgraded
• If specified, the routes property now takes precedence over host, hosts, domain and domains properties
• Correct an issue where synchronous binding and unbinding requests were not being properly handled

On behalf of the community, I am pleased to announce that the Milestone 1 (M1) of the Spring Cloud 2020.0.0 (Code Name: Ilford) Release Train is available today. The release can be found in the Spring Milestone repository. You can check out the 2020 release notes for more information.

Notable Changes in the 2020 Release Train

We have changed our release train versioning scheme. We now follow Calendar Versioning or calver for short. We will follow the YYYY.MINOR.MICRO scheme where MINOR is an incrementing number that starts at zero each year. The MICRO segment corresponds to suffixes previously used: .0 is analogous to .RELEASE and .2 is analogous to .SR2. Pre-release suffixes will also change from using a . to a - for the separator, for example 2020.0.0-M1 and 2020.0.0-RC2. We will also stop prefixing snapshots with BUILD- – for example 2020.0.0-SNAPSHOT.

Hi, Spring fans! Welcome to another installment of Spring Tips. In this installment, we’re going to look at the new support just released for building Spring Boot applications with GraalVM. We’ve looked at GraalVM and native images in another Spring Tips when we looked at Spring Fu.

GraalVM is several things. It’s a C1 replacement for a standard OpenJDK install. You can listen to this episode of my podcast, A Bootiful Podcast, with GraalVM contributor and Twitter engineer Chris Thalinger, for more details on this use of GraalVM. It lets you run regular Sring applications faster in certain conditions, and so it’s worth exploring for that reason alone.
