这个错误信息是由于在反序列化JSON字符串时，无法将字符串“2023-05-24 00:00:00”转换为LocalDateTime类型。DateTimeParseException 表示时间解析异常，它指示日期时间格式不符合ISO-8601格式。你可以检查一下传递给反序列化方法的日期时间格式是否正确。如果日期时间格式正确，那么你可以尝试使用指定的格式来反序列化日期时间字符串。例如，如果日期时间字符串的格式为“yyyy-MM-dd HH:mm:ss”，你可以使用以下代码将其转换为 LocalDateTime 类型：

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
LocalDateTime dateTime = LocalDateTime.parse("2023-05-24 00:00:00", formatter);

这样就可以将字符串转换为 LocalDateTime 类型了。
