struts与jQuery的完美整合方式之一
?plugin一定要是0.33的因为别的有错误和bug
?commons-beanutils.jar
commons-collections.jar
commons-logging.jar
commons-lang.jar
ezmorph-1.0.6.jar
json-lib-2.2.3-jdk.jar

2、服务器端处理程序
?
package com.sailor.test.action;import java.io.IOException;import java.io.PrintWriter;import java.util.ArrayList;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import net.sf.json.JSONArray;import org.apache.struts.action.Action;import org.apache.struts.action.ActionForm;import org.apache.struts.action.ActionForward;import org.apache.struts.action.ActionMapping;import com.sailor.test.action.form.LoginForm;import com.sailor.test.model.LoginDTO;/** *//** * MyEclipse Struts * Creation date: 12-28-2008 * * XDoclet definition: * @struts.action path="/login" name="loginForm" input="/login.jsp" scope="request" validate="true" */public class LoginAction extends Action { /**//* * Generated Methods */ /** *//** * Method execute * @param mapping * @param form * @param request * @param response * @return ActionForward */ public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) { System.out.println("begin"); LoginForm loginForm = (LoginForm) form; List<LoginDTO> list = new ArrayList<LoginDTO>(); LoginDTO l1 = new LoginDTO(); l1.setUsername("haiou"); l1.setPassword("sa"); LoginDTO l2 = new LoginDTO(); l2.setUsername("sailor"); l2.setPassword("123456"); LoginDTO l3 = new LoginDTO(); l3.setUsername(loginForm.getUsername()); l3.setPassword(loginForm.getPassword()); list.add(l1); list.add(l2); list.add(l3); //适用于List //Map<String, Object> map = new HashMap<String, Object>(); //map.put("userlist", list); //JSONObject json = JSONObject.fromObject(map); //适用于Map JSONArray json = JSONArray.fromObject(list); try { PrintWriter out = response.getWriter(); out.print(json); } catch (IOException e) { e.printStackTrace(); } return null; }}?
2、struts-config，web.xml不需要特殊的配置
3、login.jsp：输入用户名和密码，然后显示在本页面
