AOP实战---对用户/角色/规则操作日志记录

1.导入jar包 JDK1.7的 aop jar包必须用1.7版本的

aspectjrt-1.7.4.jar /aspectjweaver-1.7.4.jar

<dependency>
<groupId>aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.7.4</version>
</dependency>
<dependency>
<groupId>aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.7.4</version>

</dependency>

2.配置
