使用JDBC连接到数据库

Question

我需要使用java（javaFX应用程序）连接和访问数据库。当我运行该应用程序时，我在控制器sun.jdbc.odbc.JdbcOdbcDriver中发生错误。我搜查了很多，但我没有找到一个好的解决方案。我使用JDK 1.8和我使用这个类：

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); 
    } 

} 

} 

唯一的例外是在 的Class.forName（this.controlador）;

Answer 1

正如评论所说，似乎旧的JDBC/ODBC驱动程序已被弃用，并且自Java 8发布以来不再存在。看看声称是纯Java JDBC驱动程序访问这些替代实现：
