SpringMVC AJAX登录

表单

<form><input type="text" name="name" id="name"><br><input type="password"  name="password"  id="password"><br><input type="submit" value="提交" onclick="aaaa()"></form>

AJAX

function aaaa(){alert("GO");$.ajax({type:'POST',url:'${pageContext.request.contextPath}/myreqsss',contentType:'application/json;charset=UTF-8',data:JSON.stringify({"name":$("#name").val(),"password":$("#password").val()}),success:function(data){alert("SD");alert(data);}});}

后台

@ResponseBody@RequestMapping("myreqsss")public String myreq(@RequestBody JSONObject json){  String name = json.getString("name");  String password = json.getString("password");  User user = new User();  user.setName(name);  user.setPassword(password);  String ok="ok"; return ok ;}

不要忘记引入必要的包
