Every software developer knows this: there are problems with deployment again. Sometimes the build fails, even though it’s been running the whole time; other times everything is slow. And in the end, everyone sits at the application, frantically clicking around to make sure everything works. I think there’s a lot wrong here, and that’s why I’m trying to shed some light on it in this article. That’s why we’re looking at a few problems I see again and again.

Spring has been providing a reactive web client for some time. Although this client provides many settings, not everything is so obvious and simple. For example, during development I often want to see exactly how the server is responding or ignore certain errors. For this I would like to configure the client in such a way that I can notice such errors and react accordingly.
