public class DelegatingDataSource extends Object implements DataSource, InitializingBean
DataSource implementation that delegates all calls
to a given target DataSource.
This class is meant to be subclassed, with subclasses overriding only
those methods (such as getConnection()) that should not simply
delegate to the target DataSource.

public void afterPropertiesSet()
InitializingBeanBeanFactory after it has set all bean properties
and satisfied BeanFactoryAware, ApplicationContextAware etc.
This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
