本文介绍了一个简单的Struts2结合jQuery和JSON实现的AJAX示例。通过HTML页面上的按钮触发AJAX请求，使用Struts2处理请求并将数据以JSON格式返回。示例包括了web.xml和struts.xml配置文件、Action类及User类的代码。

做了个简单的struts2+jquery+json的ajax.供大家参考2010-05-12

就从请求响应的流程来写第一个是html页面

<%@ page language="java" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="s"%> <html> <head> <title>addCarInfo</title> <mce:script type="text/javascript" src="jquery-1.4.2.min.js" mce_src="jquery-1.4.2.min.js"></mce:script> <mce:script type="text/javascript" src="json.js" mce_src="json.js"></mce:script> <mce:script type="text/javascript"></mce:script> <body> <input type="button" onclick="goAjax()" value="ajax请求"/> <select id="test"></select> </body> </html>

web.xml以及struts配置

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>
   org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
  </filter-class>
</filter>

<filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
-------------------------------------------------------------------------------

struts.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

Action类:

package com.action; import java.util.ArrayList; import java.util.List; import org.apache.struts2.json.JSONException; import org.apache.struts2.json.JSONUtil; import com.opensymphony.xwork2.ActionSupport; public class Test extends ActionSupport { private String message; @Override public String execute() throws Exception { User user = new User(); user.setUserName("name1"); user.setPassword("1"); User user1 = new User(); user1.setUserName("name2"); user1.setPassword("2"); List l = new ArrayList(); l.add(user); l.add(user1); message = JSONUtil.serialize(l); return this.SUCCESS; } public String test(){ System.out.println("asd"); return this.SUCCESS; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } }
--------------------------------------------------------------------

Userl类普通的javaBean

package com.action; public class User { private String userName; private String password; public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } }
