Spring Framework 5.0 RC2 available now

Spring 15 阅读

Dear Spring community,

It’s my pleasure to announce that our second Spring Framework 5.0 release candidate is available now. This is a major revision of RC1, with refactorings in our new reactive facilities and in our new path pattern parser, as well as code style refinements all over the framework.

This release introduces a formal non-null API declaration for all of our packages, with explicitly nullable arguments and return values annotated as such now (instead of just javadoc’ed). Our nullability annotations are compliant with JSR 305 and supported by IntelliJ IDEA and upcoming versions of Kotlin, with the potential to deliver particularly strong benefits to Kotlin users (which is why we’ve rolled them into 5.0 still). Note that we apply stronger null enforcement in some Spring APIs now, superseding our previously lenient null handling.

Please give RC2 a try and let us know how it goes! Next up is an RC3 in July, shortly before we go GA, so there is still an opportunity for further refinements based on your feedback.

Cheers,
Juergen
