Spring + Hibernate + Spring

I've a project of Spring and Hibernate, but that use a lot of conections to my database (MYSQL). I know that I should implement a C3P0 to manage Pool conection but i dont know how?. Plase take me a help.

Hibernate's config:

<bean id="dataSource" class="org.springframework.jdbc.dat开发者_开发知识库asource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost/oasis"/>
    <property name="username" value="root"/>
    <property name="password" value="mysql"/>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="packagesToScan">
         <list>
            <value>com.app.oasis.model.base</value>
         </list>
    </property>
    <property name="hibernateProperties">
         <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
         </props>
    </property>
</bean>

<tx:annotation-driven/>

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

Where do I have to add the C3P0 config?

Add the C3P0 jar file (download from c3p0 website or use maven) to your classpath and create your dataSource using com.mchange.v2.c3p0.ComboPooledDataSource

<bean id="dataSource"
    class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <property name="driverClass" value="com.mysql.jdbc.Driver"/>
    <property name="jdbcUrl" value="jdbc:mysql://localhost/oasis"/>
    <property name="user" value="root"/>
    <property name="password" value="mysql"/>
    <!-- Various configuration properties can be set here -->
</bean>
