How to Define a MySql datasource bean via XML in Spring

I've looked over the documentation to define a bean. I'm just unclear on what class file to use for a Mysql database. Can anyone fill in the bean definition below?

<bean name="dataSource" class="">
    <property name="driverClassName" value="" />
    <property name="url" value="mysql://localhost/GameManager" />
    <property name="username" value="gamemanagertest" />
    <property name="password" value="1" />
</bean>

Both the answers are appropriate for the question. But just for an FYI if you're going to use DriverManagerDataSource as your datasource, every call to your datasource bean will create a new connection to your database which is not recommended for production and even it does not pool connections.

If you need a connection pool, consider Apache Commons DBCP. 

<bean name="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="jdbc:mysql://localhost:3306/GameManager" />
    <property name="username" value="gamemanagertest" />
    <property name="password" value="1" />
    <property name="initialSize" value="2" />
    <property name="maxActive" value="5" />
</bean>

Where initialSize and maxActive are pooling related properties.

To use this make sure you have the required jar in your path.

Use this class org.springframework.jdbc.datasource.DriverManagerDataSource - DriverManagerDataSource. As a best practice its better if we isolate the database values into a .properties file and configure it into our spring servlet xml configuration. In the below example the properties are stored as key-value pairs and we access the value using the corresponding key.

applicationContext-dataSource.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close">
    <property name="driverClassName" value="${jdbc.driverClassName}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
    <property name="connectionCachingEnabled" value="true"/>
</bean>

<context:property-placeholder location="classpath:jdbc.properties"/>

jdbc.propeties file:

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/sample_db
jdbc.username=root
jdbc.password=sec3ret
