准备工作，下载jquery-easyui-1.3.3.zip,以及jquery-2.0.0.js，将其放入WebRoot下，建立文件JS
为了页面引用easyui方便，建立jquery.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" href="${pageContext.request.contextPath}/js/jquery-easyui-1.3.3/themes/default/easyui.css" type="text/css"></link>
<script src="${pageContext.request.contextPath}/js/jquery-2.0.0.js" type="text/javascript" charset="utf-8"></script>
<script src="${pageContext.request.contextPath}/js/jquery-easyui-1.3.3/jquery.easyui.min.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/jquery-easyui-1.3.3/locale/easyui-lang-zh_CN.js" charset="utf-8"></script>
然后创建登录页面
<%@ page language="java" import="java.util.*" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

以及userController,由于是示例，就任意账号密码都能登录成功
package cn.cy.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import cn.cy.dto.Json;
import cn.cy.dto.TuserDto;
@Controller
@RequestMapping("/userController")
public class UserController {
@RequestMapping("/login")
@ResponseBody
public Json login(TuserDto user){
Json json = new Json();
json.setSuccess(true);
json.setMsg("OK");
return json;
}
}
Json类代码为
package cn.cy.dto;
public class Json implements java.io.Serializable {
private boolean success = false;
private String msg = "";
private Object obj = null;
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public Object getObj() {
return obj;
}
public void setObj(Object obj) {
this.obj = obj;
}
}
TuserDto 类代码为
package cn.cy.dto;
import java.util.Date;
import org.springframework.format.annotation.DateTimeFormat;
import cn.cy.model.Tdept;
public class TuserDto {
private String user_id;
private String login_name;
private String passwd;
private String real_name;
private String phone_number;
private String dept_id;
private String group_ids;
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getLogin_name() {
return login_name;
}
public void setLogin_name(String login_name) {
this.login_name = login_name;
}
public String getPasswd() {
return passwd;
}
public void setPasswd(String passwd) {
this.passwd = passwd;
}
public String getReal_name() {
return real_name;
}
public void setReal_name(String real_name) {
this.real_name = real_name;
}
public String getPhone_number() {
return phone_number;
}
public void setPhone_number(String phone_number) {
this.phone_number = phone_number;
}
public String getDept_id() {
return dept_id;
}
public void setDept_id(String dept_id) {
this.dept_id = dept_id;
}
public String getGroup_ids() {
return group_ids;
}
public void setGroup_ids(String group_ids) {
this.group_ids = group_ids;
}
}
