PostConstruct

PostConstruct methods are invoked on the newly constructed instance, after any dependency injection has been performed by the container and before the first business method is invoked on the bean.

PostConstruct methods are invoked in an unspecified transaction and security context.

PreDestroy

PreDestroy methods execute after any method annotated with the Remove annotation has completed.

PreDestroy methods are invoked in an unspecified transaction and security context.
