Question

可能重复：
@AspectJ pointcut for all methods of a class with specific annotation

我正在尝试为具有自定义注释的类的所有方法编写切入点。这是代码

注释：

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(value = RetentionPolicy.RUNTIME)
@Target(value = ElementType.METHOD)
public @interface ValidateRequest {}

控制器中的方法：

 @RequestMapping(value = "getAbyB", produces = "application/json")
 @ResponseBody
 @ValidateRequest
 public Object getAbyB(@RequestBody GetAbyBRequest req) throws Exception { 
     /// logic
 }

方面：

 @Aspect
 @Component
 public class CustomAspectHandler {
     @Before("execution(public * *(..))")
     public void foo(JoinPoint joinPoint) throws Throwable {
         LOG.info("yippee!");
     }
 }

的applicationContext：
```
`<aop:aspectj-autoproxy />`
```

我一直在尝试下面提到的各种建议，但似乎没有任何建议（除了上面使用的建议外）

@Around("@within(com.pack.Anno1) || @annotation(com.pack.Anno1)")
@Around("execution(@com.pack.Anno1 * *(..))")

Answer 1

这应该有效：

 @Aspect
 @Component
 public class CustomAspectHandler {
    @Pointcut("execution(@ValidateRequest * *.*(..))")
    public void validateRequestTargets(){}

     @Around("validateRequestTargets()")
     public Object foo(JoinPoint joinPoint) throws Throwable {
         LOG.info("yippee!");
         return joinPoint.proceed();
     }
 }

切入点将所有方法与自定义注释匹配
