Method Detail
afterPropertiesSet
public final void afterPropertiesSet() throws IllegalArgumentException, BeanInitializationException
Description copied from interface:InitializingBeanInvoked by the containingBeanFactoryafter it has set all bean properties and satisfiedBeanFactoryAware,ApplicationContextAwareetc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

IllegalArgumentExceptionBeanInitializationException
checkDaoConfig
protected abstract void checkDaoConfig() throws IllegalArgumentException
Abstract subclasses must override this to check their configuration.Implementors should be marked as
finalif concrete subclasses are not supposed to override this template method themselves.- Throws:
IllegalArgumentException- in case of illegal configuration
initDao
protected void initDao() throws Exception
Concrete subclasses can override this for custom initialization behavior. Gets called after population of this instance's bean properties.- Throws:
Exception- if DAO initialization fails (will be rethrown as a BeanInitializationException)- See Also:
