关注 module-info.java见 Declare Spring modules with JDK 9 module metadata发出最后一次提交:

This issue is marked as "General Backlog", indicating that we won't deal with it for 5.1 (otherwise it'd be marked for 5.1 GA still) and probably not in subsequent 5.x releases either (otherwise it'd be marked as "5.x Backlog").

Specifically, we can't ship module-info files quite yet since we'd need stable module names for all of our optional dependencies... and many of those don't declare stable module names at this point (that is, they don't even include an Automatic-Module-Name manifest entry in their jar). Also, we'd need to build the entire framework on JDK 9+ for the compiler to understand the module-info.java format which is not entirely trivial either, even if the framework itself is known to work fine with JDK 9/10/11 at runtime.

All in all, my prediction about module-info files for 5.1 turned out to be too ambitious. Our current focus is on general JDK 11 compatibility (SPR-16391) on the classpath and as automatic modules on the module path, as well as GraalVM compatibility (SPR-16991). The use of jlink requires manual addition of module-info.class files to the framework jars for the time being... which might stay that way for several years still until we ship a JDK 11 baselined Spring Framework 6.0 against a new generation of dependencies.
