<!-- ============== RESOURCE DEFINITIONS ========= -->

<!-- Local DataSource that works in any environment -->

<bean id="dataSource"

class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="driverClassName">

<value>${jdbc.driverClassName}</value>

</property>

<property name="url">

<value>${jdbc.url}</value>

</property>

<property name="username">

<value>${jdbc.username}</value>

</property>

<property name="password">

<value>${jdbc.password}</value>

<!--DriverManagerDataSource

Simple implementation of the standard JDBC DataSource interface, configuring the plain old JDBC DriverManager via bean properties, and returning a new Connection from every getConnection call. 

NOTE: This class is not an actual connection pool; it does not actually pool Connections. It just serves as simple replacement for a full-blown connection pool, implementing the same standard interface, but creating new Connections on every call
