From Spring Boot 2 to Spring Boot 3 with Java 21 and Jakarta EE

Summary:

Jakarta EE 9 changed its package namespace from `javax.*` to `jakarta.*`. This may sound like a trivial change that mostly affects Jakarta EE. So, why should Spring developers care?

As it turns out, the namespace changes ripple throughout the entire Java ecosystem. And Spring is no exception. Spring Framework 6 and Spring Boot 3 raised their baseline to Jakarta EE 9 API level which is supported by Tomcat 10 and Jetty 11 for example. Attending this session will teach you how to make this migration as smooth as possible. A live coding demo will take you through the steps involved, and point out where to pay special attention.

We will also briefly examine some of the changes planned for **Jakarta EE 11** that will prepare you for what to expect in future versions of Spring.
