【Spring-AOP-学习笔记-3】@Before前向增强处理简单示例

项目结构

程序代码

HelloImpl.java

WorldImpl.java

定义切面类

package org.crazyit.app.aspect;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
// 定义一个切面
@Aspect
public class AuthAspect
{
// 匹配org.crazyit.app.service.impl包下所有类的、
// 所有方法的执行作为切入点
@Before("execution(* org.crazyit.app.service.impl.*.*(..))")
public void authority()
{
System.out.println("模拟执行权限检查");
}
}
