Dear Spring community,

Please note that 5.3 is designed as the final 5.x feature release, wrapping up the major themes in the Spring Framework 5 generation, in particular reactive programming and Kotlin support, while also taking GraalVM compatibility to the next level. Last but not least, we are not only preparing for JDK 15 and 16 but also for next year’s JDK 17 LTS already, expecting an extended 5.3.x maintenance life.

Getting Started With RSocket: Spring Security

Reading time: about 6 minutes
Coding time: about 20 minutes

If you’ve been following my series on RSocket, you’ve already learned how to build client-server applications with Spring Boot. In today’s exercise, you’re going to learn how to add security to your RSocket applications.

The task of securing RSocket applications is greatly simplified when you use Spring Security. Spring Security is a must-have module for any production application. It allows you to easily plugin many different authentication providers and restricts each user’s access to your application based on their identity and their role.

Spring Tips: Spring and GraalVM (pt. 2)

speaker: Josh Long (@starbuxman)

Hi Spring fans! Welcome to a very special, interregnum episode of Spring Tips where we revisit Spring and GraalVM native images. I wanted to get this video out in light of the recent Spring Graal 0.7.1 release which drastically simplifies things even compared to the last time we looked at Spring and Graal waaay back in April 2020.

TL;DR: GraalVm is a JIT replacement that you can use with a stock-standard JVM, and that’s worth looking into in its own right. GraalVM also offers a separate feature supporting native image compilation. This native-image builder takes bytecode and turns it into an architecture-specific binary that sheds the JVM and embeds something called SubstrateVM. Native images are fast to startup and they take way less memory at runtime. These qualities make it desirable in a containerized, cloud-centric environment.
