可以使用Timestamp.from()方法将Instant对象转换成Timestamp对象。以下是示例代码: 代码解读 importjava.sql.Timestamp;importjava.time.LocalDateTime;importjava.time.ZoneId;importjava.time.ZonedDateTime;publicclassMain{publicstaticvoidmain(String[]args){LocalDateTimedateTime=LocalDateTime.now();ZonedDateTimezonedD...

其中,java.sql.Timestamp是java.util.Date的子类,可以存储日期和时间信息,而且可以精确到秒甚至毫秒。在将数据库中的datetime类型数据转换为Java类型时,我们通常使用JDBC(Java Database Connectivity)进行操作。JDBC提供了从数据库检索数据并将数据存储到数据库的方法。在处理datetime类型数据时,我们可以使用java.sql.Time...
