Java在mysql数据库中插入datatime时间数据

//将时间字符串转Timestamp类型
public static Timestamp string2Time(String dateString) throws ParseException { 
    DateFormat dateFormat; 
    dateFormat = new SimpleDateFormat("yyyy-MM-dd kk:mm:ss", Locale.ENGLISH); 
    dateFormat.setLenient(false); 
    java.util.Date timeDate = dateFormat.parse(dateString);//util类型 
    Timestamp dateTime = new Timestamp(timeDate.getTime());//Timestamp类型,timeDate.getTime()返回一个long型 
    return dateTime; 
}

Timestamp t = string2Time("2018-07-27 12:25:00");

//组织sql语句
String sql = "insert into table values('"+t+"');";
