Java、XML与数据库编程实践(三)

  文件DbInput.java则是真正的数据拷贝部分：

import java.sql.*;

public class DbInput

{

    Connection src=null;

    Connection dest=null;

    Connection connformax=null;

    ConnPara srcPara;

    ConnPara destPara;

    public DbInput(){}

    public void dbInit()

    {

        DbXmlParser xmlparser=new DbXmlParser("dbs.xml");

        srcPara=xmlparser.getSource();

        destPara=xmlparser.getDest();

        try {

           Class.forName("sun.jdbc.odbc.JdbcOdbcDriver" );

           Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");

           src = DriverManager.getConnection( srcPara.getUrl(), srcPara.getUsername(),srcPara.getPassWord());

           dest =DriverManager.getConnection( destPara.getUrl(), destPara.getUsername(),destPara.getPassword());

           connformax= DriverManager.getConnection( destPara.getUrl(), destPara.getUsername(),destPara.getPassword());

        }

        //捕捉加载驱动程序异常

        catch ( ClassNotFoundException cnfex ) {

           System.err.println( "装载 JDBC/ODBC 驱动程序失败。" );

           cnfex.printStackTrace();

           System.exit( 1 );  // terminate program

        } catch ( SQLException ex )

        {

            System.err.println( "连接失败" );

            ex.printStackTrace();

            System.exit( 1 );  // terminate program

        }          

    }
