Question

Hi all following is my database connection file,

package org.slingemp.common;

import java.sql.Connection;
import java.sql.DriverManager;

public class JDBCManager {

    public Connection mysqlConnection()  {
        Connection dbConnection = null;
        try {

          Class.forName("com.mysql.jdbc.Driver");
          dbConnection=DriverManager.getConnection("jdbc:mysql://localhost:3306/slingemp","root","root");
          //System.out.println("mysql Driver Connedted::::::::");

        } catch (Exception e) {
            e.printStackTrace();
        }
        return dbConnection;

    }
}

in this i want to make connection string and driver name configurable. how to do this and where to put the file which contains configurable values?

Regards
Tony

Answer 1

You can put them into .properties file or server JNDI resources.

jdbc.properties example:

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/yourDatabaseName
jdbc.username=username
jdbc.password=password

Then in java class use this to get properties:

public static ResourceBundle getJdbcBundle() {
    return ResourceBundle.getBundle("jdbc");
}

String url = SomeClass.getJdbcBundle().getString("jdbc.url");

But more efficient way would be to use JNDI.
