Timestamp和LocalDateTime 轉換

1.Timestamp 轉 LocalDateTime 
Timestamp time = Timestamp.from(Instant.now());
LocalDateTime localDateTime = time.toLocalDateTime();

2.LocalDateTime  轉 Timestamp
Timestamp time = Timestamp.valueOf(LocalDateTime.now());

 

3.Timestamp類型可以直接從json中取出

Timestamp timestamp = (Timestamp) data.get("date_time");
