Question

我想发送 2 个日期到 Spring 休息点。我试过这个：

start_date=2019-03-03T21:25:24.000Z&end_date=2019-03-03T21:25:29.000Z

休息终点：

    @GetMapping("/terminals")
    public ResponseEntity<Map<Integer, List<TopTerminalsDTO>>> getTopTerminals(
            @RequestParam(value = "start_date", required = true) String start_date,
            @RequestParam(value = "end_date", required = true) String end_date) {

        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS");
        LocalDateTime start_dateTime = LocalDateTime.parse(start_date, formatter);
        LocalDateTime end_dateTime = LocalDateTime.parse(end_date, formatter);

        final List<PaymentTransactionsDailyFacts> list = dashboardService.findTop_Terminals(start_dateTime, end_dateTime);

但我得到了例外：

2019-03-10 13:22:46,677 INFO  [stdout] (default task-1) 13:22:46.676 [default task-1] ERROR o.s.b.w.s.support.ErrorPageFilter - Forwarding to error page from request [/dashboard/terminals] due to exception [Text '2019-03-03T21:22:39.000Z' could not be parsed, unparsed text found at index 23]

你知道我该如何解决这个问题吗？

编辑：

LocalDateTime start_dateTime = LocalDateTime.parse(start_date, DateTimeFormatter.ISO_INSTANT);
        LocalDateTime end_dateTime = LocalDateTime.parse(end_date, DateTimeFormatter.ISO_INSTANT);

我得到：23:15:21,554 INFO [stdout] (default task-3) java.time.format.DateTimeParseException: Text '2019-03-19T23:15:14.000Z' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {NanoOfSecond=0, InstantSeconds=1553037314, MicroOfSecond=0, MilliOfSecond=0},ISO of type java.time.format.Parsed

Answer 1

这是因为根据你的DateTimeFormatter start_date 是无效的。不期望在日期的最后有Z。

你有两个选择。

1. 从您的start_date 和end_date 中删除Z 字符。
2. 修改 DateTimeFormatter 以也接受 ZoneOffset。

例子：

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSSX");

您还可以决定是否不需要 start_date 中的几分之一秒。如果没有，你可以使用这个技巧：

LocalDateTime start_dateTime = LocalDateTime.parse("2019-03-03T21:25:24Z", DateTimeFormatter.ISO_INSTANT);
