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

很明显，时间转换错误
代码报错行：
 
LocalDateTime.parse("2020-04-03 14:57:41");
 
解决方案：
DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
LocalDateTime parse = LocalDateTime.parse("2020-04-03 14:57:41",df);
