Struts2+JSON+JQuery简单示例
一、所需jar包
commons-logging-1.1.1.jar
commons-collections-3.1.jar
commons-digester-2.0.jar
commons-beanutils-1.7.0.jar
xstream-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.5.jar
javassist-3.11.0.GA.jar
ognl-3.0.1.jar
struts2-core-2.2.3.jar
xwork-core-2.2.3.jar
commons-fileupload-1.2.2.jar
freemarker-2.3.16.jar
?
struts2-json-plugin-2.2.3.jar
json-lib-2.2.3-jdk15.jar
dom4j-1.6.1.jar
ezmorph-1.0.6.jar
?
二、index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%><script type="text/javascript" src="js/jquery-1.4.2.js" ></script><script type="text/javascript"><!--$(document).ready(function(){$("#registerButton").click(function(){var url = "json.action";var params = {"uid":$("#uid").attr("value")};$.getJSON(url,params,function callback(data){var user = eval("("+data+")");$("#result").each(function(){$(this).html("welcome ,"+user.uid);});});return false;})});//--></script> <html> <head> <title>JSON Page</title> </head> <body> <s:form method="post" id="form"> <table align="center"> <tr> <td> <s:textfield label="USERNAME" name="uid" id="uid"/> </td> <td> <s:div id="result" cssStyle="color:#ff0000;"/> </td> </tr> <tr> <td colspan="2"> <s:submit id="registerButton" value="JSON"/> </td> </tr> </table> </s:form> </body> </html> ?
三、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"><struts><constant name="struts.enable.DynamicMethodInvocation" value="true"/><constant name="struts.i18n.encoding" value="UTF-8"/> <package name="json" extends="json-default"> <action name="json" method="jsonTest"> <result type="json"> <param name="root">result</param> </result> </action> </package></struts>
?
四、JSONAction
package com.s2ajax.exer.web.actions;import java.util.HashMap;import java.util.Map;import net.sf.json.JSONObject;import com.opensymphony.xwork2.ActionSupport;public class JSONAction extends ActionSupport{/** * */private static final long serialVersionUID = -7645203344502656194L;private String uid ;private String result;public String getUid() {return uid;}public void setUid(String uid) {this.uid = uid;}public String jsonTest(){Map<Object,Object> map = new HashMap<Object,Object>();map.put("uid", getUid());JSONObject jsonObj = JSONObject.fromObject(map);result = jsonObj.toString();return SUCCESS;}public String getResult() {return result;}public void setResult(String result) {this.result = result;}}? 1 楼 zhucelogin 2011-11-02 不错，包括要导入的架包也挺正确，学习了，最近也在做jquery easy ui+struts2的
