Database Connection Pooling in Hibernate

I was looking for a way to control connection pooling in Hibernate inside a Spring environment. God bless Apache foundation for their amazing code helps, as I found the answers in DBCP. Which-ever hibernate session factory you use, use the following data source bean in your configuration xml to control connection pooling:

    <bean id="internalDataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="org.postgresql.Driver"/>
        <property name="url" value="jdbc:postgresql://127.0.0.1/myDatabase"/>
        <property name="username" value="root"/>
        <property name="password" value="abc123"/>
        <property name="maxIdle" value="5"/>
        <property name="maxActive" value="25"/>
        <property name="minIdle" value="5"/>
        <property name="initialSize" value="5"/>
    </bean>

For all options and details, refer the API for BasicDataSource. And, if you are a maven user, don't forget to include the dependency:

        <dependency>
            <groupId>commons-dbcp</groupId>
            <artifactId>commons-dbcp</artifactId>
            <version>1.2.2</version>
        </dependency>
