Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied.
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.

Specified by:

afterPropertiesSet in interface InitializingBean
