Java格式化解析时间

System.out.println(DateTimeFormatter.ofPattern("yyyyMMddHHmmssSSS").format(LocalDateTime.now(ZoneOffset.UTC)));
		DateTimeFormatter DATE_TIME_FORMATTER = new DateTimeFormatterBuilder()
				// 解析date+time
				.appendPattern("yyyyMMddHHmmss")
				// 解析毫秒数
				.appendValue(ChronoField.MILLI_OF_SECOND, 3).toFormatter();
		System.out.println(LocalDateTime.parse("20191112133503997", DATE_TIME_FORMATTER));
