Struts2的这个功能相信已经有很多了。。我这个是相对来说极其简单的实现。相信一看就明白。
首先要引如jquery.1.3.2.min.js。引入struts2必须的六个包。。还要引入
json-lib-2.3-jdk13.jar、struts2-json-plugin-2.1.8.1.jar?、ezmorph-1.0.6.jar
commons-logging-1.1.1.jar、commons-lang-2.5.jar、commons-collections-3.2.jar、
commons-beanutils-1.8.3.jar包。引入完后。先看看index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0">
<script type="text/javascript" src="${pageContext.request.contextPath }/jquery/jquery-1.3.2.min.js"></script> <script type="text/javascript"> function clickButton() { //alert($('#name').val()); var url = "hello"; var params = { name:$("#name").val(), pass:$("#pass").val() }; jQuery.post(url, params, callbackFun, 'json'); } function callbackFun(data) { alert(data.result);//对应HelloWorld类的message属性 //获取数据后渲染页面 } </script> </head> <body> <input id="name" type="text"> <input id = "pass" type="text"> <input type="button" value="ok" onclick="javascript:clickButton();"> </body> </html>

然后就是struts2配置
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="ajax" extends="json-default"> <action name="hello" class="com.vo.HelloWorld"> <result type="json" /> </action> </package> </struts>
?完了就是类文件了
package com.vo; import com.opensymphony.xwork2.ActionSupport; public class HelloWorld extends ActionSupport { private static final long serialVersionUID = 1035615877474749202L; private String name; private String result; private String pass; // ajax请求参数赋值 public void setName(String name) { this.name = name; } public void setPass(String pass){ this.pass = pass; } // ajax返回结果 public String getResult() { return result; } public String execute() { this.result = name+pass; System.out.println(pass); return "success"; } }

就大功告成了。底下有例子。别忘记下jar包。可以下载。可以运行的。
