使用JDBC连接到数据库

Question

我需要用java (javaFX应用程序)连接和访问数据库。在运行应用程序时，控制器sun.jdbc.odbc.JdbcOdbcDriver中有一个错误。我找了很多东西，但没有找到一个好的解决办法。我使用jdk 1.8，我使用这个类：

public class conexionBD {

private Connection conexion;
private Statement sentencia;

private String controlador;
private String nombre_bd;
private String usuarioBD;
private String passwordBD;


public conexionBD(){
    this.controlador="sun.jdbc.odbc.JdbcOdbcDriver"; 
    this.nombre_bd="C:\\Users\\SANDRA\\Documents\\Access_BD\\Contactos.mdb";
    this.usuarioBD="";
    this.passwordBD="";

}

public void EstablecerConexion(){

    try{
        Class.forName (this.controlador);
    }catch (ClassNotFoundException e){
        JOptionPane.showMessageDialog(null, "Error al cambiar el controlador");
        e.printStackTrace();
    }

    try{
        String DSN="jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ="+this.nombre_bd;
        conexion=DriverManager.getConnection(DSN,this.usuarioBD,this.passwordBD); 
    }catch (SQLException e){
         JOptionPane.showMessageDialog(null,"Error al realizar la conexion "+e);
    }

    try { 
        this.sentencia=this.conexion.createStatement( 
        ResultSet.TYPE_SCROLL_INSENSITIVE, 
                ResultSet.CONCUR_READ_ONLY); 
    } 
    catch (Exception e) { 
        JOptionPane.showMessageDialog(null,"Error al crear el objeto sentencia "+e);
    }

}

}

例外在Class.forName (this.controlador)中；

正如注释所指出的，似乎旧的JDBC/ODBC驱动程序已经过时，并且自Java 8发布以来就不再存在了。请看一下这些声称是纯java访问驱动程序的替代实现：

第一个是有14天试用许可证的商业实现，第二个是免费的。希望你能找到有用的东西！
