Spring aop by annotation on controller method does not work

Question

Annotation

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface MyAnnotation {
    String value();
}

AOP

@Aspect
@Component
public class MyAspect {

@Around("@annotation(MyAnnotation)")
public Object aroundHandler(ProceedingJoinPoint joinPoint) throws Throwable {
    ...
}

Controller

@Controller
public class MyController {

    @RequestMapping(value="/hello", method=RequestMethod.GET)
    @ResponseBody
    @MyAnnotation(value="hello")
    public String hello() {
        return "hello";
    }
}

in above condition, my aop does not work...
It works fine with other methods, which is not annotated by @Controller .
And it works fine with aop expression and controller method.

Is it possible to use aop by annotation with controller method?

Answer 1

Try this:

@Around("@annotation(myAnnotation)")
public Object aroundHandler(ProceedingJoinPoint joinPoint,MyAnnotation myAnnotation) throws Throwable {
    // Do Something
}
