struts2 以注解的形式实现拦截器

package com.example.struts.action;

import java.util.Map;


import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.interceptor.annotations.*;

public class LoginAction extends ActionSupport {
	private String username;
	@Before
	public void myBefore() {
		System.out.println("调用myBefore方法");
//		return LOGIN;
	}
	@After
	public void myAfter() throws InterruptedException {
		Thread.sleep(5000);
		System.out.println("----调用myAfter方法");
	}
	@BeforeResult
	public void myBeforeResult() {
		System.out.println("----调用myBeforeResult方法");
	}
	public String execute() throws Exception {
		System.out.println("调用execute方法");
		return SUCCESS;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		System.out.println("---调用set方法" + username);
		this.username = username;
	}
