Use a DateTimeFormatterto format the value of LocalDateTimethe way you want it...
使用 aDateTimeFormatter以LocalDateTime您想要的方式格式化值...
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss", Locale.US);
String strLocalDate = "2015-10-23T03:34:40";
LocalDateTime localDate = LocalDateTime.parse(strLocalDate, formatter);
System.out.println(localDate);
System.out.println(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").format(localDate));
System.out.println(DateTimeFormatter.ofPattern("HH:mm:ss yyyy-MM-dd ").format(localDate));
Which prints...

Remember, date/time objects are just a container for amount of time which has passed since a fixed point in time (like the Unix epoch), they don't have a internal/configurable format of their own, they tend to use the current locale's format.
请记住，日期/时间对象只是自固定时间点（如 Unix 纪元）以来已经过去的时间量的容器，它们没有自己的内部/可配置格式，它们倾向于使用当前语言环境的格式。
Instead, when you want to present the date/time value, you should first use a DateTimeFormatterto format the date/time value to what ever format you want and display that
相反，当您想要显示日期/时间值时，您应该首先使用 aDateTimeFormatter将日期/时间值格式化为您想要的格式并显示它

Opps, missed that part.
哎呀，错过了那部分。
In this case, you should be converting your Date/Time values to use java.sql.Timestampand using a PreparedStatementto insert/update them
在这种情况下，您应该转换要使用的日期/时间值java.sql.Timestamp并使用 aPreparedStatement来插入/更新它们

String localTime = "2018-09-13 00:00:00";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss", Locale.ENGLISH);
LocalDateTime date = LocalDateTime.parse(localTime, formatter);
String replace = date.toString().replace("T", " ");
System.out.println(replace);

Simple option using the Joda-Timelibrary.
使用Joda-Time库的简单选项。
new LocalDateTime(DateTimeZone.forID("Europe/London")).toString().replace("T", " ");
