Have you ever wondered what options are available in the Spring ecosystem to help developers define and build APIs?
In this talk, we will go over what options are available to Spring Developers to build APIs. We will cover traditional HTTP APIs as well as alternative protocols for messaging and streaming APIs. We will introduce other projects from the Spring portfolio that can enhance developer productivity in creating and consuming APIs.

There’s many options for a Garbage Collector in the JVM today. With more Java apps already on, or moving to the cloud, what is the best GC to use? The answer: it depends!
In this session, we’ll quickly review GC and memory usage in the JVM, then dive into scenarios where certain GC’s would be better than others. Along the way, we’ll talk about the experimental GC called LXR.

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?
Attend this session to learn 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

Profilers help to analyze performance bottlenecks of your application if you know how to use them. Getting to grips with profilers helps to understand how they work: Profilers aren't rocket science. A usable Java profiler can be written in 240 lines of pure Java code, allowing you to fix performance issues and add custom features quickly. This talk will give the fundamentals of Java profiling and an overview of existing open-source profilers.
