java - 无法解析，在索引 23 处找到未解析的文本

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);

但我得到了异常(exception):

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](默认任务3)java.time.format.DateTimeParseException:无法解析文本'2019-03-19T23:15:14.000Z':无法从 TemporalAccessor 获取 LocalDateTime:{NanoOfSecond=0、InstantSeconds=1553037314、MicroOfSecond=0、MilliOfSecond=0}、java.time.format.Parsed 类型的 ISO

Answer 1

这是因为根据您的 DateTimeFormatter start_date 无效。不希望在日期的最后出现 Z。

您有 2 个选择。

1. 从 start_date 和 end_date 中删除 Z 字符。
2. 修改 DateTimeFormatter 以接受 ZoneOffset。

示例:

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);
