一般发生这样的错误的原因，是由于你的通知方法有参数，需要在@Pointcut( "execution(* com.fishwasser.action.UserAction.*(..))" ) 添加args()。

如果是@AfterReturning，那么就需要配置returning参数。如：

   /**
     * 日志记录功能
     */
    @AfterReturning(returning="result" ,pointcut="execution(* cn..*.*Service.*(..))")
    public void log(Object result){
        if(result ==null){
            System.out.println("数据库中无结果...");
        }else{
            System.out.println("数据库中有结果...");
        }
    }

如果是@AfterThrowing ，那么需要配置throwing参数。如下代码：

   /**
     * 模拟异常处理
     */
    @AfterThrowing(pointcut="execution(* cn..*.*Service.*(..))",throwing="ex")
    public void processException(Throwable ex){
        System.out.println("异常信息为："+ex.getMessage());
    }
