The initMethod and destroyMethod  are attributes of Spring @Bean annotation to perform certain actions upon bean initialization and destruction.  initMethod  is called after bean initialization and the  destroyMethod  is called before bean destruction by container. Annotations  @PostConstruct and @PreDestroy , standardized by JSR-250, are generally considered the best practice for obtaining lifecycle callbacks in a modern Spring application.   initMethod and destroyMethod are alternatives to InitializingBean and DisposableBean .

Annotations @PostConstruct and @PreDestroy, standardized by JSR-250, are generally considered the best practice for obtaining lifecycle callbacks in a modern Spring application. @PostConstruct annotation defines a method that will run only once, just after the initialization of bean. @PreDestroy annotation defines a method that will run only once, just before Spring removes the bean from the application context.
