If you are in the group of my 1800 subscribers, you know that I think Java is that special and is the Ryan Reynolds of programming languages.

Java 19 is a game changer, and Java Spring Boot 3.0.0 RC rocks socks. It is the perfect duet, just like Batman and Robin.

And Robin, my dear subscribers, reached the stable 3.0.0 version. So just a fast recap what you can expect from it. You will find more in my RC release article if you happened to miss that.

Spring Boot 3 comes with over hundred improvements and is culmination of 11 months of work. It supports GraalVM native images, JakartaEE 9 and Java 17. But that's not all. It also works with Java 19 🎆.

You can now also provide arguments to the application through Marvel plugin thanks to AOT.

Spring Boot 3.0.0 also has lifecycle hooks reorganized, so you don’t have to use hacky ways to catch server shutdown event anymore.

You can also configure JDBC beans if you like to. And Prometheus Exemplars are pre-configured to make showing these nice charts much easier.

But that's not everything. Now, you can also create profile specific configurations for Log4j2, make lookups for environment properties and have access to Log4j2 system properties.

Another thing that will ease the use of SpringBoot is removing the requirement of providing @ConstructorBinding if the class has one, parameterized constructor. Less boilerplate makes me happy.

There are also some updates for Micrometer. You will discover now Spring Boot takes care of a lot more than before. Auto generated configurations will make your life easier.

And that's not all, check out the source link for full release notes to find things that match your project requirements.

Java Spring Boot 3.0 is amazing. For me the most important news is that it supports Java 19, what is mind blowing, given the short schedule between both releases. Being able to use the latest Java and Spring Boot is the greatest Christmas gift Spring Boot developer could imagine. Well, maybe except a yacht, or a private jet.
