Spring Plugin： Issue with Adding an Interface to SpringMVC

[homejim]

springboot: 1.4.0.RELEASE
Action: Added an interface.
Problem: After adding, the request reports parameter errors. The error log is as follows:

    "timestamp": 1729508119180,
    "status": 500,
    "error": "Internal Server Error",
    "exception": "java.lang.IllegalArgumentException",
    "message": "Name for argument type [java.lang.Integer] not available, and parameter name information not found in class file either.",
    "path": "/role223"
}

Seems like caching problem, could you supply reporoducer?

I tried it, and springboot 1.4.6.RELEASE still reports errors. However, springboot 1.4.7.RELEASE does not have this issue. The corresponding versions are spring 4.3.8.RELEASE and spring 4.3.9.RELEASE. It seems that some classes were modified between these two versions.

After downloading:

Step1:Run directly.
Step2:Uncomment the test2 interface in TestController.
Step3: Request the interface test2.
Following these steps will reproduce the issue. If you change the version in pom.xml to 2.0.0.RELEASE, it runs well.

Thanks for the clarification, it wasn’t clear from the initial message what you meant by term 'interface.' Do you think it's necessary to fix this since the issue affects versions < 1.4.7-RELEASE and it's already fixed in the newer ones? What does @cvictory think about it?

My initial judgment is that there might have been some changes in the caching of certain classes, which is why the older versions have issues. The fix should be relatively simple. If it is simple, I think we should adapt it to make hotswap more universally applicable.

If no one else addresses it, I will consider handling it when I have time.
