Spring Framework 7 and Spring Boot4 use JSpecify as standard non-null/nullable annotations, so we now have them automatically configured in @vscode.dev as well as the Spring Tools for @eclipseide.org distribution 🥳

And what a giant pleasure to welcome you to my home town… 😎🥳🤗

Always awesome to meet Mr Spring 🍃 Tools 🧰 @martinlippert.bsky.social in person

Quick heads-up: the option to disable the new symbol generation via the internal Spring index will go away soon. So if you have this feature disabled for some reason, let us know why, so that we can fill in the missing gaps in the new implementation to enable a smooth transition

The new logical structure view in the @springtools.bsky.social does not only group things in well-known pre-defined stereotypes. You can bring your own custom stereotypes and include them in the structure as well, for example by defining them in catalog files 🚀

Did you know that you can influence the grouping of the elements in the new logical structure view? Click on the grouping icon on the project node and select which groups you would like to enable/disable - and the view will automatically update accordingly 😎

The new logical structure view for your Spring Boot projects is based on the stereotypes concept of JMolecules. And stereotype nodes in the structure view allow you to quickly navigate to the corresponding catalog file - in case you wonder how the stereotype definition looks like 🧐
