Spring Core | BeanFactoryPostProcessor | Example

Image
In Spring, the  BeanFactoryPostProcessor is a  functional interface that contains a abstract method postProcessBeanFactory .   It allows us to modify the Spring context’s bean definitions before any beans get created.  BeanFactoryPostProcessor can create new bean definitions or modify existing ones. Since  BeanFactoryPostProcessor  should be called before other bean types are formed, it must be registered as a static method level. BeanFactoryPostProcessor example We are creating a simple maven project. You could clone the code from our GitHub repo.

Spring initMethod and destroyMethod Example

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 .
