I am using a custom annotation called @Toggle on top of a rest controller class in spring boot to intercept the handlerType to block rest calls.
See below code snippet:
@RestController
@Toggle(feature="feature.foo")
@RequestMapping("/foo")
public class FooController {
@RequestMapping("")
public Map hello() {
return Collections.singletonMap("message", "hello foo!");
}
}
But I am not able to access the api which fails even before dispatcher servlet find the handler method.

Found below logs which can throw some more light on the problem.

However, if I use the same @Toggle annotation on a method inside rest controller class, the handler mapping finds the right method to invoke.
@RequestMapping("/foo")
@Toggle(feature = "feature.foo")
public Map hello() {
return Collections.singletonMap("message", "hello foo!");
}
How can I make sure spring boot maps to right handler method even if I use custom annotation on top of rest controller.
