Here’s an example to show you how to connect to MySQL database via JDBC driver.

1. Download MySQL JDBC Driver

Get a MySQL JDBC driver from here -MySQL JDBC Driver Download Here

2. Java JDBC connection example

Code snippets to use JDBC to connect a MySQL database.

  Class.forName("com.mysql.jdbc.Driver");
  Connection connection = null;
  connection = DriverManager.getConnection(
          "jdbc:mysql://hostname:port/dbname","username", "password");
  connection.close();

See a complete example below :
File : JDBCExample.java

package com.mkyong.common;
 
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
 
public class JDBCExample {
 
	public static void main(String[] argv) {
 
		System.out.println("-------- MySQL JDBC Connection Testing ------------");
 
		try {
 
			Class.forName("com.mysql.jdbc.Driver");
 
		} catch (ClassNotFoundException e) {
 
			System.out.println("Where is your MySQL JDBC Driver?");
			e.printStackTrace();
			return;
 
		}
 
		System.out.println("MySQL JDBC Driver Registered!");
		Connection connection = null;
 
		try {
			connection = DriverManager
					.getConnection("jdbc:mysql://localhost:3306/mkyongcom",
							"root", "password");
 
		} catch (SQLException e) {
			System.out.println("Connection Failed! Check output console");
			e.printStackTrace();
			return;
		}
 
		if (connection != null) {
			System.out.println("You made it, take control your database now!");
		} else {
			System.out.println("Failed to make connection!");
		}
	}
}

3. Run it

Assume JDBCExample.java is store in c:\test folder, together with MySQL JDBC driver

C:\test>java -cp c:\test\mysql-connector-java-5.1.8-bin.jar;c:\test JDBCExample
-------- MySQL JDBC Connection Testing ------------
MySQL JDBC Driver Registered!
You made it, take control your database now!
 
C:\test>

Done.
