Hi, Spring fans! Welcome to another installment of This Week in Spring! As I write this, I'm in sunny Stockholm, Sweden for the JForum #123 installment. This is, apparently, the first time the meetup is completely full up since before the pandemic, with more than 150 people in attendance! Tak, Stockholm!

Then, tomorrow, I'm off to beautiful Barcelona, Spain, for the amazing Spring I/O event. I'll be doing part of the keynote with Spring AI founder Dr. Mark Pollack; I'll be looking at Spring's rich integration with AOT and GraalVM with GraalVM founder Thomas Wuerthinger; and I'll be doing…

Your First Spring AI 1.0 Application

by Dr. Mark Pollack, Christian Tsolov, and Josh Long

Hi, Spring fans! Spring AI is live on the Spring Initializr and everywhere fine bytes might be had. Ask your doctor if AI is right for you! It's an amazing time to be a Java and Spring developer. There's never been a better time to be a Java and Spring developer, and this is doubly true in this unique AI moment. You see, 90% of what people talk about when they talk about AI engineering is just integration with models, most of which have HTTP APIs. And most of what these models take is just human-language Strings. This is integration code, and what place for these integrations to exist than hanging off the side of your Spring-based workloads? The same workloads who business logic drives your organizations and which guard data that feeds your…

Last month, we explored how to secure Spring AI MCP Servers[1] with the OAuth2 authorization framework. In the conclusion of that article, we mentioned we'd explore using standalone Authorization Servers for MCP Security and deviate from the then-current specification.

Since we published the article, the community has been very active in revising the original version of the specification. The new draft is simpler, and the major change does match what we had imagined for security. MCP Servers are still OAuth2 Resource Servers, meaning they authorize incoming requests using access tokens passed…
