public interface InitializingBean
An alternative to implementing InitializingBean is specifying a custom init-method, for example in an XML bean definition. For a list of all bean lifecycle methods, see the BeanFactory javadocs.
void afterPropertiesSet() throws Exception
This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.
Exception - in the event of misconfiguration (such
as failure to set an essential property) or if initialization fails.
