Question

请帮助检查此方法。当我尝试使用邮递员发布数据时，我收到错误http状态400。这种方法有什么错误吗？

@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());
}

这是我的时间戳类：

使用Postman的Json数据

 {
 "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
}

查找我默认的日期格式应该是ISO 8601（看起来你正在使用codehaus进行json解析）。我建议您查找如何定义如何解析日期或在JSON中更改日期格式（如果可能）
