<util:properties id="DB"location="classpath:db.properties"/> <!--Configuring connection pooling--<bean id="DS" class="Org.apache.commons.dbcp.BasicDataSource"Destroy-method="Close"> <property name="Driverclassname"Value="#{db.driver}"/> <property name="URL"Value="#{db.url}"/> <property name="username"Value="#{db.user}"/> <property name="Password"Value="#{db.pwd}"/> <property name="InitialSize"Value="#{db.initsize}"/> </bean>
