QSqlDatabase db=QSqlDatabase::addDatabase("QMYSQL");//添加驱动
    db.setHostName("127.0.0.1");//ip地址
    db.setDatabaseName("stu");//数据库名
    db.setUserName("root");//用户名
    db.setPassword("123456");//密码
    if (db.open())
    {
        qDebug()<<"open successful";  //如果连接成功打印 open successful
    }
    else
    {
        qDebug()<<"error"; //连接失败打印error
