aop获取注解的方法

private static ActionControllerLog giveController(JoinPoint joinPoint) throws Exception {
    Signature signature = joinPoint.getSignature();
    MethodSignature methodSignature = (MethodSignature) signature;  
    Method method = methodSignature.getMethod();  
         
    if(method != null) {
        return method.getAnnotation(ActionControllerLog.class);
    }
    return null;
}
```

其中注解为
```
import java.lang.annotation.Documented;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import java.lang.annotation.ElementType;
import java.lang.annotation.RetentionPolicy;
 
@Target({ElementType.PARAMETER, ElementType.METHOD})    
@Retention(RetentionPolicy.RUNTIME)    
@Documented   
public @interface ActionControllerLog {
    /** 标题 */
    String title()  default "";
    /** 动作的名称 */
    String action() default "";
    /** 是否保存请求的参数 */
    boolean isSaveRequestData() default false;
    /** 渠道 */
    String channel() default "web";
}
```
