Hi, Spring fans! Welcome to another installment of Spring Tips. In this episode we're going to look at the new Kotlin DSL for Spring Security. I love Kotlin. I introduced Kotlin in several other Spring Tips videos: The Kotlin Programming Language, Bootiful Kotlin Redux, and Spring's Support for Coroutines. Some of those videos are very old! There are already a number of different projects in the Spring diaspora that are shipping Kotlin DSLs. They include, among others, Spring Framework, Spring Webflux, Spring Data, Spring Cloud Contract and Spring Cloud Gateway. And now, Spring Security!

Spring Security is an amazing project - it solves some of the hardest problems in the industry and helps people secure their applications. And, as if that weren't enough, it's displayed a steadfast determination to make security easy. If you ever used Spring Security in its earliest incarnations, you'd know that it required loads of XML - pages! - to get anything done. That improved to the point where in Spring Security 3 you…

Hi, Spring fans! Welcome to another installment of This Week in Spring! This week, I'm home, in San Francisco, California, in the US, where the fears around Coronavirus have heated up and made things problematic for those of us who travel. It looks like, at least for the immediate future, I'll be - basically - grounded. Stay safe out there, my friends.

The good news is that this will let me get to a ton more other things like the blogs, A Bootiful Podcast and Spring Tips and of course my Reactive Spring book. And of course, we've got a ton of things to get to today in today's installment of This Week in Spring, so…

In the diverse world of microservices, HTTP is the undisputed leader in agent-to-agent communications. It’s mature, well established, and everywhere. But in some cases, HTTP request-response can be cumbersome. What if you need communication patterns beyond traditional request-response, such as fire-and-forget or streaming? And what if you want to send messages in either direction?

With HTTP, there are ways to achieve this but it’s not what the protocol was built for. Many of the solutions come with additional tradeoffs or shortcomings. Plus, here’s no rulebook that…
