Announcing Spring Native Beta!
Today, after one year and half of work, I am pleased to announce that we’re launching the beta release of Spring Native and its availability on start.spring.io! In practice, that means that in addition to the regular Java Virtual Machine supported by Spring since its inception, we are adding beta support for compiling Spring applications to native images with GraalVM in order to provide a new way
Spring Boot 2.4.0 available now
On behalf of the Spring Boot team and everyone that has contributed, I am pleased to announce that Spring Boot 2.4.0 has been released and is available from Maven Central. 2.4.0 is the first generally available Spring Boot release that uses the new versioning scheme. Please note that the version is 2.4.0 rather than 2.4.0.RELEASE that you may have expected based on previous releases. This release
Config file processing in Spring Boot 2.4
Spring Boot 2.4.0.M2 has just been released, and it brings with it some interesting changes to the way that application.properties and application.yml files are loaded. If your applications use the fairly typical setup of only using a single application.properties or application.yml file, then you’ll probably not notice any difference. If, however, you have applications that use more complex setup
Spring Shell
Users of the Spring Shell project can easily build a full featured shell ( aka command line) application by depending on the Spring Shell jars and adding their own commands (which come as methods on spring beans). Creating a command line application can be useful e.g. to interact with your project’s REST API, or to work with local file content. Features Spring Shell’s features include A simple, an

Lazy Initialization in Spring Boot 2.2
The recently announced first milestone of Spring Boot 2.2 introduces support for lazy initialization. This post describes the new functionality and explains how and when to enable it. What Does it Mean to be Lazy? Spring Framework has had support for lazy bean initialization since before its source code moved to Git 11 years ago. By default, when an application context is being refreshed, every be
Memory footprint of the JVM
The JVM can be a complex beast. Thankfully, much of that complexity is under the hood, and we as application developers and deployers often don't have to worry about it too much. With the rise of container-based deployment strategies, one area of complexity that needs some attention is the JVM's memory footprint. Two kinds of memory The JVM divides its memory into two main categories: heap memory
Spring Boot in a Container
Many people are using containers to wrap their Spring Boot applications, and building containers is not a simple thing to do. This is an article for developers of Spring Boot applications, and containers are not always a good abstraction for developers - they force you to learn about and think about very low level concerns - but you will on occasion be called on to create or use a container, so it
Spring Framework's Migration from Jira to GitHub Issues
We used the opportunity to streamline the Jira field values, so for example 25 component values in Jira correspond to 5 "in: *" labels on GitHub. The "status: *" and the "type: *" labels have also been given extra through and revised. Our choice of labels is aligned with the labels used in Spring Boot. The Boot team has given their process and labels a lot of thought, and we know the consistency w

A massive thank you to everyone that has contributed, and to all the early adopters that have been providing vital feedback on the
Spring Cloud Contract in a polyglot world
