controller 返回json数据
@ResponseBody
//查看用户信息 ?json @RequestMapping(value="/{username}",method=RequestMethod.GET) @ResponseBody //直接返回response里的io流数据，不需要加载视图 public Map<String, User> view(@PathVariable String username){ // return userList.get(username); return userList; }
jsp页面获取值：
$.each()的使用是难点
<script type="text/javascript" src="${pageContext.request.contextPath}/resources/js/jquery-1.11.3.min.js"> </script> <script type="text/javascript"> $(function(){ alert(1); $.getJSON("/SpringMVC-C02_05/user/hhhh/zs",function(data){ alert(data); $.each(data,function(key,val){ $("#div").append("<span>"+val.userName+"</span><br/>"); }); }); }); </script> <body> <div id="div" style="200px;height:200px;border:1px solid red"></div> </body> </html>
