[Java教程]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

 1 package com.homework.filter; 2  3 import org.aspectj.lang.ProceedingJoinPoint; 4 import org.aspectj.lang.annotation.Around; 5 import org.aspectj.lang.annotation.Aspect; 6 import org.aspectj.lang.annotation.Before; 7 import org.springframework.stereotype.Component; 8  9 /**10  * Created by ytt on 2017/1/11.11 */12 13 @Aspect14 @Component15 public class LoginCheckAspect {16 17   @Around(value = "@annotation(org.springframework.web.bind.annotation.RequestMapping)")18   public Object checkUser(ProceedingJoinPoint pjp) throws Throwable {19 20     //获取参数21     Object[] args = pjp.getArgs();22     System.out.println("在进入方法之前");23     //放行24     Object proceed = pjp.proceed();25     System.out.println("执行完方法之后");26     return proceed;27   }28 29   @Before("execution(* com.homework.controller..*.*(..))")30   public void before(){31     System.out.println("在方法执行之前执行");32   }33 }

这样就能完成拦截了
