使用Spring AOP来进行权限验证

使用Spring AOP前需要先引入相应的包

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.8.10</version>
</dependency>

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.8.10</version>
</dependency>

然后创建切面类

 package com.homework.filter;

 import org.aspectj.lang.ProceedingJoinPoint;
 import org.aspectj.lang.annotation.Around;
 import org.aspectj.lang.annotation.Aspect;
 import org.aspectj.lang.annotation.Before;
 import org.springframework.stereotype.Component;

 /**
  * Created by ytt on 2017/1/11.
  */

 @Aspect
 @Component
 public class LoginCheckAspect {

     @Around(value = "@annotation(org.springframework.web.bind.annotation.RequestMapping)")
     public Object checkUser(ProceedingJoinPoint pjp) throws Throwable {

         //获取参数
         Object[] args = pjp.getArgs();
         System.out.println("在进入方法之前");
         //放行
         Object proceed = pjp.proceed();
         System.out.println("执行完方法之后");
         return proceed;
     }

     @Before("execution(* com.homework.controller..*.*(..))")
     public void before(){
         System.out.println("在方法执行之前执行");
     }
 }

这样就能完成拦截了
