關於前後端不在統一服務器的跨域設置Cookie問題

1.後端允許跨域調用，並添加Cookie

	@CrossOrigin
	@RequestMapping(value="/login", produces = "application/json; charset=utf-8", method=RequestMethod.POST)
	@ApiOperation(value = "用戶登錄")
	@ApiImplicitParams({
		@ApiImplicitParam(name = "name", value = "用戶名", required = true, dataType = "string"),
		@ApiImplicitParam(name = "pwd", value = "密碼", 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.驗證
		result ret = new result(200, "登錄成功", 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.前端允許跨域

form.on('submit(hug_adminLogin)', function(data) {
		console.log(data.field)
		
		// 登錄
		$.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);
				}
			}
		});
	})

結果：

但是在Application裏面都沒有Cookie,所以下次請求了，也沒帶上 

 

問題就是怎麼才能帶上Cookie
