======================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);
 }
