Three ways to register the JDBC driver

Three ways to register the JDBC driver

1. The Com.mysql.jdbc.Driver object obtained through the imported JDBC driver package is registered with the Drivermanager.registerdriver (driver) of the Java.sql.DriverManager object.

2. Get the Com.mysql.jdbc.Driver object through class reflection and register with the Drivermanager.registerdriver (driver) of the Java.sql.DriverManager object.

3. Get the drive reflex class, auto Register

        // The first way        New Driver ();        Drivermanager.registerdriver (driver);         // The second way        Driver d = (Driver) class.forname ("Com.mysql.jdbc.Driver"). newinstance ();        Drivermanager.registerdriver (d);         // The Third Way        Class.forName ("Com.mysql.jdbc.Driver");  // Automatic Registration
