I teach a course in java and springboot for beginners. I would like to walk my students through the code of a real world java or springboot application. Can anyone recommend a good example?

So I'm making a project in SpringBoot with Oauth security.

If I use Auth0 as my Authorization Server, I can register an application there and just say that I want user to be able to login with Google an Facebook. That's all it takes.

If I use Keycloak as my Authorization Server, I can also have users choose Google or Facebook as there prefered login, but in order to provide that, I have to register my app with Google and Facebook first.

So how come it's so easy with Auth0 and a little less easy with Keycloak? Is it a contract thing, does Auth0 have contracts with all these providers or something?

In this blog post, we will explore how to detect and prevent these anti-patterns using pair programming, code reviews, and observability.

In this article, we’ll examine cache misses and, in general, learn about the caching concept and how to implement it in Spring Boot.

“An issue introduced by macOS 14.4, which causes Java process to terminate unexpectedly, is affecting all Java versions from Java 8 to the early access builds of JDK 22. There is no workaround available, and since there is no easy way to revert a macOS update, affected users might be unable to return to a stable configuration unless they have a complete backup of their systems prior to the OS update.”
