Creating Connections with DataSource Class

This section describes how to create connection objects with the DataSource class.

It is recommended now that connection objects are created by the DataSource implementation class, com.mysql.jdbc.jdbc2.optional.MysqlDataSource. Here is a sample program that creates a connection object using the DataSource class without using JNDI services:

/* MySqlDataSource.java
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
 */
import java.sql.*;
import javax.sql.*;
public class MySqlDataSource {
  public static void main(String [] args) {
    Connection con = null;
    try {

// Setting up the DataSource object
      com.mysql.jdbc.jdbc2.optional.MysqlDataSource ds 
        = new com.mysql.jdbc.jdbc2.optional.MysqlDataSource();
      ds.setServerName("localhost");
      ds.setPortNumber(3306);
      ds.setDatabaseName("HerongDB");
      ds.setUser("Herong");
      ds.setPassword("TopSecret");

// Getting a connection object
      con = ds.getConnection();
      
// Getting database info
      DatabaseMetaData meta = con.getMetaData();
      System.out.println("Server name: " 
        + meta.getDatabaseProductName());
      System.out.println("Server version: "
        + meta.getDatabaseProductVersion());

// Closing the connection
      con.close();
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());
    }
  }
}

The output confirms that I got a good connection. Remember to include mysql-connector-java-5.0.7-bin.jar in the classpath for compilation and execution:

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\javac 
   -cp .;\local\lib\mysql-connector-java-5.1.36-bin.jar 
   MySqlDataSource.java

C:\herong>\Progra~1\java\jdk1.8.0_45\bin\java 
   -cp .;\local\lib\mysql-connector-java-5.1.36-bin.jar 
   MySqlConnectionUrl

Server name: MySQL
Server version: 5.5.15
