Spring MVC: 400 bad request The request sent by the client was syntactically incorrect

Question

Please help to check this method. I got error http status 400 when I tried to post data using postman. Is there any mistake in this method?

@RequestMapping(value = "/Timestamp", method = RequestMethod.POST)
    @ResponseBody
    public Timestamp newTimestamp(@RequestBody Timestamp timestamp) {
        System.out.println("Test: "+ timestamp);
        timestampService.saveTimestamp(timestamp);
        return timestampDAO.findTimestampByPrimaryKey(timestamp.getId());
}

And This is my Timestamp class:

Json data using Postman

 {
 "id":4,
 "loginDate":"01/30/2016 12:12:12 AM",
 "logoutDate":"01/30/2016 12:12:12 AM",
 "createDate":"01/30/2016 12:12:12 AM",
 "updateDate":"01/30/2016 12:12:12 AM",
 "isActive":true
}

how does the JSON look you send with postman,, can you post it? — kamokaze, Mar 23 '16 at 20:25
The data you send has to map to the properties. For example you have an argument called timestamp and nothing in your JSON represents this. Also if you are posting either you need to create an object that represents all of the values or else determine which value you want. see http://stackoverflow.com/questions/11291933/requestbody-and-responsebody-spring. — ismoore999, Mar 23 '16 at 22:18
Sorry thought your Timestamp class was the standard Timestamp. Can you post that class too — ismoore999, Mar 23 '16 at 22:21
ok, well the pointer I can give you is to look up is that the date formats I believe by default are expected to be ISO 8601 (looks like you are using codehaus for your json parsing). I suggest you look up how to define how a date is to be parsed. — ismoore999, Mar 24 '16 at 16:08
