🍃 #SpringFramework 7.1 will support @⁠MockitoBean and @⁠MockitoSpyBean on test constructor parameters! 🚀

It works with Java constructors, but it's even nicer with Kotlin compact constructors. It also works with so-called "test records" in Java. 🤓

Happy assertions!

Let me introduce you to another new validation in the Spring Tools: it reminds you that you should not try to define the path in the controller annotation itself - and as a bonus, comes with the corresponding quick fix 🥳

Spring Framework 7 comes with an improved way to functionally register bean definitions using the BeanRegistrar interface - and Spring Tools 5 has already support for this built-in, incl. understanding bean definitions + checking and adding matching import annotations 🥳🚀😎

The newly introduced API versioning support in Spring Framework 7 is already nicely supported in the @springtools.bsky.social - for example by double checking for a proper configuration when using it 😎

New in Spring Tools 5: controllers now show up with a code lens that summarizes the web configuration that you have in place for the project - and allows you to quickly navigate to it - very useful, especially in combination with the new API versioning support in Spring Framework 7 🥳 🚀
