Hi, Spring fans! Welcome to another installment of This Week in Spring!

• Sam Brannen shares some good news: a null-safe Index operator for the Spring Expression Language (SpEL) is coming to Spring Framework 6.2!
• This is interesting, and a nice application of AI (do I even need to spell out "artificial intelligence" anymore?): localize applications with Spring AI
• this is a neat guide by community member Wim Deblauwe over on InfoQ: A Practical Guide to Building an API Back End with Spring Boot - version 2
• James Ward, founder of the WebJars project and a legend in his own right, invites folks to contribute feedback on the new webjars-locator-lite module, created by the…

A few Java libraries have shown up recently that use text templates, but compile to Java classes at build time. They can thus claim to some extent to be "reflection free". Together with potential benefits of runtime performance, they promise to be easy to use and integrate with GraalVM native image compilation, so they are quite interesting for people just getting started with that stack in Spring Boot 3.x. We take a look at a selection of libraries (JStachio, Rocker, JTE and ManTL) and how to get them running.

The source code for the samples is in GitHub and each template engine has its own…

Hi, Spring fans! Happy one-day-belated Java 22 release day to those who celebrate! To ring in the new release, we've got an extra special and incredible discussion with a Java legend - somebody who's been involved in the Java community and work for decades - Stuart Marks, or "Dr. Deprecator," as he's affectionately known in the community.

Hi, Spring fans! In this installment we look at the Exposed Object Relational Mapper framework for Kotlin. #Kotlin #Java #JDBC #springboot

update I've since published a Spring Tips video on this very topic! If you'd prefer, you could watch that instead.

Hi, Spring fans! Happy Java 22 release day, to those who celebrate! Did you get the bits already? Go, go, go! Java 22 is a significant improvement that I think is a worthy upgrade for everyone. There are some big, final released features, like Project Panama, and a slew of even-better preview features. I couldn't hope to cover them all, but I did want to touch on a few of my favorites. We're going to touch on a number of features. The code, if you want to follow along at home, is here (https://github.com/spring-tips/java22)…

I'm excited to share that there will be support for the OAuth 2.0 Token Exchange Grant (RFC 8693) in Spring Security 6.3, which is available for preview now in the latest milestone (6.3.0-M3). This support provides the ability to use Token Exchange with OAuth2 Client. Similarly, server-side support is also shipping with Spring Authorization Server in 1.3 and is available for preview now in the latest milestone (1.3.0-M3).

OAuth2 Client features of Spring Security allow us to easily make protected resources requests to an API secured with OAuth2 bearer tokens. Similarly, OAuth2 Resource Server…

Hi, Spring fans! In this week's installment we talk Rob Winch, lead of Spring Security and founder of the exciting new project Spring Boot Testjars.

Front end development these days is dominated by large JavaScript client side frameworks. There are plenty of good reasons for that, but it can be very inefficient for many use cases, and the framework engineering has become extremely complex. In this article, I want to explore a different approach, one that is more efficient and more flexible, built from smaller building blocks, and well-suited to server side application frameworks like Spring (or similar tools in a range of server side languages). The idea is to embrace the concept of hypermedia, imagine how a next-generation browser would…
