关于前后端不在统一服务器的跨域设置Cookie问题

1.后端允许跨域调用，并添加Cookie

	@CrossOrigin@RequestMapping(value="/login", produces = "application/json; charset=utf-8", method=RequestMethod.POST)@ApiOperation(value = "用户登录")@ApiImplicitParams({@ApiImplicitParam(name = "name", value = "用户名", required = true, dataType = "string"),@ApiImplicitParam(name = "pwd", value = "密码", required = true, dataType = "string")})@ApiResponses({@ApiResponse(code = 200, message = "result", response = result.class)})public Object login(HttpServletRequest request,HttpServletResponse response,@RequestParam(value="name")String name,@RequestParam(value="pwd")String pwd) {System.out.println("login:");//1.验证result ret = new result(200, "登录成功", 0, tutil.currMSecs(), null);//略//response.setHeader("Access-Control-Allow-Credentials", "true");response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));String sSessionId = UUID.randomUUID().toString().replaceAll("-", "");;Cookie ck = new Cookie(sdpt.SEN_ID, sSessionId);ck.setPath("/");ck.setMaxAge(30*1000*60);response.addCookie(ck);HttpSession session = request.getSession();session.setAttribute(sdpt.SEN_ID, sSessionId);return ret;}

2.前端允许跨域

form.on('submit(hug_adminLogin)', function(data) {console.log(data.field)// 登录$.ajax({type: "post",url:  'http://xx.xxx.xx.xxx:8080/xxxx/syssetup/login',data: {name : 'xxxx',pwd  : 'x'},dataType: "json",xhrFields: {withCredentials:true},crossDomain: true,success: function(res){console.log(res);if(res.code == 200){layer.msg(res.msg);}else{layer.msg(res.msg);}}});})

结果：

结果2

但是在Application里面都没有Cookie,所以下次请求了，也没带上 

问题就是怎么才能带上Cookie
