Spring AOP如何匹配接口方法上的注释？

Question

I use mybatis. My question is how can Spring AOP matches annotation on interface method? Because I want to put some param in annotation and then handle them in afterReturning method.

my annotation:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface CacheClear {
    String key() default "";
}

in mapper class:

@CacheClear
List<BizInst> selectAllBizInsts();

and in my aspect:

when use "execute..." it works

@AfterReturning("execution(public * com.dao.*.select*(..))")
public void doAfterReturning(){
    System.out.println("after returning");
}

but when use "@annotation(...)" it doesn't work

@AfterReturning("@annotation(com.annotation.CacheClear)")
public void doAfterReturning(){
    System.out.println("after returning");
}

You can do something like that for selecting your public dao methods annotated with CacheClear annotation:

@Pointcut("execution(@com.yourPackage.CacheClear * *(..))")
public void methodAnnotatedWithCacheClear( ) {}

@Pointcut("execution(public * com.dao.*.select*(..))")
public void publicDAOMethod() {}

@AfterReturning(pointcut = "methodAnnotatedWithCacheClear() && publicDAOMethod()", returning = "result")
public void doStuff(JoinPoint joinPoint, Object result) {
