java在mysql数据库插入当前时间

首先获得当前时间

java.util.Date currentTime = new java.util.Date();

1、如果数据库的字段类型为date

java.sql.Date date = new java.sql.Date(currentTime.getTime());

2、如果数据库的字段类型为time

java.sql.Time time = new java.sql.Time(currentTime.getTime());

3、如果数据库的字段类型为datetime

java.sql.Timestamp timeStamp = new java.sql.Timestamp(date.getTime());

测试：

public class TestDate {
	public static void main(String[] args) {
		java.util.Date currentTime = new java.util.Date();
		System.out.println(currentTime);
		java.sql.Date date = new java.sql.Date(currentTime.getTime());
		System.out.println(date);
		java.sql.Time time = new java.sql.Time(currentTime.getTime());
		System.out.println(time);
		java.sql.Timestamp timeStamp = new java.sql.Timestamp(date.getTime());
        System.out.println(timeStamp);
	}
}
