将Unix时间戳转换为Java日期，Spring RequestParam [英] Convert Unix timestamp to Java Date, Spring RequestParam

问题描述

以下是 fullcalendar js 发送到服务器的请求。

Following is a request fullcalendar js send to the server.

http://localhost:8080/NVB/rest/calendar/events?start=1425168000&end=1428796800 400

如何在Spring Request Param中指定日期模式（ @DateTimeFormat ）以将此时间转换为Date对象。我尝试了不同的模式，但收到405错误的请求。

How to specify Date pattern (@DateTimeFormat) in Spring Request Param to convert this time to a Date object. I tried different patterns but getting 405 Bad Request.

@RequestMapping(value = "/events", method = RequestMethod.GET)
public @ResponseBody List<EventDto> addOrder(@RequestParam(value = "start") @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) Date start,
                                             @RequestParam(value = "end") @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)   Date end) {
    LOGGER.info("Requesting event from [{}] to [{}]", start, end);
    return new LinkedList<EventDto>();
}

推荐答案

因为时间戳不是格式化的日期（通过Java的 SimpleDateFormat 选项进行选择），但更多的是数字值：如果您经常这样做，我建议为Date对象创建一个自定义数据绑定器这个单一实例。参见 http：//docs.spring .io / spring / docs / current / spring-framework-reference / htmlsingle /＃portlet-ann-webdatabinder

Since timestamps aren't a formatted date (going by Java's SimpleDateFormat options), but more a numeric value: I would recommend making a custom data-binder for Date objects if you're doing this more often than this single instance. See http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#portlet-ann-webdatabinder

作为一种一次性解决方案，您可以将它们绑定到 Long 参数，并使用 new Date（start）创建自己的Date对象。

As a one-off solution you can bind them to Long parameters and create your own Date object with new Date(start).
