package org.crazyit.app.aspect;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;// 定义一个切面@Aspectpublic 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"); } }
