 <!-- <aop:aspectj-autoproxy/> -->不需要这个
 

 <bean id="securityHandler" class="annotationSecurityHandler.SecurityHandler" />

   <aop:pointcut id="allMethod" expression="execution(* managerImpl.UserManagerImpl.add*(..))|| execution(* managerImpl.UserManagerImpl.del*(..))"/>

======================SecurityHandler1 .java==============================

package annotationSecurityHandler;

import org.aspectj.lang.JoinPoint;

public class SecurityHandler1 {

 private void checkSecurity(JoinPoint j){//取得代理类传递的参数

  Object obj[] = j.getArgs();

  for(Object o :obj){

   System.out.println(o);

  }

  System.out.println("========checkSecurity=="+j.getSignature().getName());//这个是获得方法名

 }

}

===============test.java==================================

public static void main(String[] args) {

  BeanFactory beanFactory = new ClassPathXmlApplicationContext("applicationContext.xml");

  UserManager userManager = (UserManager) beanFactory.getBean("userManager");

  userManager.addUser("123", "aaa");

  userManager.deleteUserById(1);

 }
