This Week in Spring - June 22nd, 2021

Hi, Spring fans! How’re y’all doing? Can you believe we’re almost halfway through this crazy little thing called 2021? Time sure flies when you’re having fun! This week was no exception. I joined the my buddy Matt Raible and Brian Demeers today for the OktaDev Twitch channel and we hacked on making the Spring Boot starter for Okta work with Spring Native. The goal is that you should be able to bring your application unchanged with Spring Native, and this is yet another example of that working. We didn’t know what issues we were going to face, but we managed to figure out the relatively minor things required to make it work within an hour and within two hours we had most a working, standalone “hints” .jar dependency that users can add to their spring-aot plugins dependencies. Hopefully they’ll polish that off and publish the bits soon.

This Week in Spring - June 15th, 2021

Hi, Spring fans! How’re you doing? I’m silly stoked! This week saw the release of Spring Native 0.10.0 and it is awesome! You absolutely have to check this release out. I put together an episode of Spring Tips, the most comprehensive of its kind, introducing (almost) everything you’ll need to know about Spring Native and Spring Native 0.10.0 in particular. Start here. Spring Native is awesome and this is the comprehensive introduction I wish I’d had at the start.

The next time we meet in this humble column, next week, will be June 22nd, and by then we’ll have passed summer solstice - the longest day in the year! - and the beginning of summer. Farewell (for now) to Spring, the season, and long live Spring, the easiest and most productive path to production for your applications.

This Week in Spring - June 8th, 2021

Hi, Spring fans! What’s shaking? It’s one of those weeks where, even though the thing I wanted to happen - a vacation with the family - didn’t happen, what did happen - accidentally lots of free time with no meetings - has turned out wonderfully. It was all I could do to pry myself from the IDE to pull together this week’s roundup, but I am glad I did! There’s a ton of great stuff there. Let’s dive into it.

"Wiremock" for RSocket

If you have an application that connects to an RSocket server at runtime, how do you test it? We need a way for a test to start a server and tell us where it is listening, and then we need to be able to register request and response examples (a.k.a. "contracts"). That’s what this project provides - it’s like Wiremock but for RSocket.

Getting Started

The easiest way to use the project is as a JUnit (Jupiter) extension, e.g:

@SpringBootTest
@ExtendWith(RSocketServerExtension.class)
class SocketsApplicationTests {
	...
}

With this extension installed the Spring Boot tests will run with an RSocket server listening on a port given by test.rsocket.server.port, so the test can connect directly to it, or (more likely) the code that it is testing will connect to it. You might need to tell it where to connect via the @SpringBootTest annotation, e.g. if the application is looking for a property at runtime called rsocket.port:

@SpringBootTest("rsocket.port=${test.rsocket.server.port}")
@ExtendWith(RSocketServerExtension.class)
class SocketsApplicationTests {
	...
}
