When accessing databases in Spring you commonly use a dataSource.xml file of some description to hold the XML stanzas describing the connection details to various databases or schemas. When dealing with multiple dataSource requirements you might find that more than one logical dataSource bean name actually points to the same physical connection. Rather than define multiple datasource stanzas with exactly the same details, Spring allows the use of the element to point easily to an existing bean but use a different name: <bean id="personDataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <property name="url" value="jdbc:oracle:thin:@database:port:SID" /> <property name="username" value="USER" /> <property name="password" value="PASS" />
