Answer 1

The default ways of formatting a java.util.Date (or java.sql.Timestamp) has only millisecond precision. You can use yyyy-MM-dd hh:mm:ss.SSS to get that millisecond precision.

A java.sql.Timestamp actually does have (up to) nanosecond precision (assuming the database server and the driver actually support it). The easiest way to format it in Java 8 is to convert the timestamp to a java.time.LocalDateTime (using Timestamp.toLocalDateTime()) and use the java.time formatting options in java.time.format.DateTimeFormatter which support up to nanoseconds.

If you use Java 7 or earlier it will take some extra effort, as the normal date formatters don't support it. For example you could use a dateformatter with pattern yyyy-MM-dd hh:mm:ss (to only format up to seconds) and append the sub-second nano seconds (with appropriate zero-padding) of Timestamp.getNanos() yourself.
