javascript - JSON : The request sent by the client was syntactically incorrect

Question

我有以下电话

$.getJSON("/svrBooking/json/getEmployeesByManager",{
            manager: "Paul Walker",
            endDate: endDate, --> "Thu May 28 16:52:25 BST 2015"
            startDate: startDate, --> "Thu Apr 30 16:52:25 BST 2015"
            ajax: 'true'
            }, function (result) {...});

这正在调用以下Java代码

@RequestMapping(value="/getEmployeesByManager" , method = RequestMethod.GET)
    public @ResponseBody ReservationsCount
    getEmployeesByManager(Model model,@RequestParam String manager,@RequestParam Date startDate, @RequestParam Date endDate) throws ParseException{...}

我收到以下错误

GET 'http://localhost:8080/svrBooking/json/getEmployeesByManager?manager=Paul+Walker&endDate=Thu+May+28+16%3A52%3A25+BST+2015&startDate=Thu+Apr+30+16%3A52%3A25+BST+2015&ajax=true'   400 bad request

回复说

The request sent by the client was syntactically incorrect.

当我将 Date 对象传递给 getJSON 调用时，这种情况才开始发生。如果我将日期更改为字符串，一切正常。有谁知道这是怎么回事吗？

看看this所以问题。
Spring不知道如何解析Date参数。您必须在 @RequestParam 之后添加 @DateTimeFormat 注释来告诉 Spring 需要哪种格式。例如:

@RequestParam @DateTimeFormat("MMddyyyy") Date startDate

在 Javascript API 调用中，您必须以指定的格式传递日期。

您还应该能够使用 ISO 格式(我尚未测试过):

@RequestParam @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) Date startDate

然后在 Javascript API 调用中，您应该使用 toISOString 格式化日期:

$.getJSON("/svrBooking/json/getEmployeesByManager",{
            manager: "Paul Walker",
            endDate: endDate.toISOString(), --> "2015-06-26T08:38:26.175Z"
            startDate: startDate.toISOString(), --> "2015-06-26T08:38:45.304Z"
            ajax: 'true'
            }, function (result) {...});
