How does the agent SpringMVC plugin intercept annotations on interfaces?

[kiwi9607]

@RestController
public interface UserClient {
@RequestMapping("/save")
JSONObject save();
}

If the current plugin doesn't work, you need to adjust method match, bydebuddy should have to way of matching method annotations from parent interface.
I didn't use in this way though.

Thank you for your reply. The current plugin is not working properly. For code like this, I will adjust the placement of the Spring MVC instrumentation, such as in doDispatcher or elsewhere.

Will future versions of the MVC plugin support this kind of syntax?

I think you could simply change plugin method matcher to follow this.

Something like

ElementMatcher.Junction<MethodDescription> hasAnnotationDirectlyOrOnInterface =
    ElementMatchers.isAnnotatedWith(xxx.class)
        .or(ElementMatchers.isOverriddenFrom(
            ElementMatchers.isAnnotatedWith(xxx.class)
        ));

plugin work relies on community, I don't know that. I have shared the proposed way, should be easy to change. But we need to test it anyway.
No plan from my personal perspective.

Okay,I can write test cases to verify it.
