SpringMVC框架，json

需求：以前点击个人明细的时候，是新开一个窗口进行展示，现在我们要实现的效果是点击明细的时候，直接在当前页面的下方进行明细信息的展示。并且页面不刷新。

这就需要是用ajax来实现异步请求。

首先在userlist.jsp页面中添加一个div,用来存放要展示的明细信息的条目

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@include file="/WEB-INF/jsp/common/head.jsp"%>
        <div class="right">
            <div class="location">
                <strong>你现在所在的位置是:</strong>
                <span>用户管理页面</span>
            </div>
            <div class="search">
           		<form method="post" action="${pageContext.request.contextPath }/user/userlist.html">
					<input name="method" value="query" class="input-text" type="hidden">
					 <span>用户名：</span>
					 <input name="queryname" class="input-text"	type="text" value="${queryUserName }">
					 
					 <span>用户角色：</span>
					 <select name="queryUserRole">
						<c:if test="${roleList != null }">
						   <option value="0">--请选择--</option>
						   <c:forEach var="role" items="${roleList}">
						   		<option <c:if test="${role.id == queryUserRole }">selected="selected"</c:if>
						   		value="${role.id}">${role.roleName}</option>
						   </c:forEach>
						</c:if>
	        		</select>
					 
					 <input type="hidden" name="pageIndex" value="1"/>
					 <input	value="查 询" type="submit" id="searchbutton">
					 <a href="${pageContext.request.contextPath}/user/useradd.html" >添加用户</a>
				</form>
            </div>
            <!--用户-->
            <table class="providerTable" cellpadding="0" cellspacing="0">
                <tr class="firstTr">
                    <th width="10%">用户编码</th>
                    <th width="20%">用户名称</th>

                </tr>
                   <c:forEach var="user" items="${userList }" varStatus="status">
