java.time.format.DateTimeParseException: Text '2020-04-03 14:57:41' could not be parsed at index 10

很明顯，時間轉換錯誤

代碼報錯行：

LocalDateTime.parse("2020-04-03 14:57:41");

解決方案：

DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
LocalDateTime parse = LocalDateTime.parse("2020-04-03 14:57:41",df);
