Spring JSR-250 Annotations

Spring has JSR-250 based annotations which include @PostConstruct, @PreDestroy and @Resource annotations.

  • @PostConstruct: This annotation can be used as an alternate of initialization callback.

  • @PreDestroy: This annotation can be used as an alternate of destruction callback.

  • @Resource : This annotation can be used on fields or setter methods. The @Resource annotation takes a 'name' attribute which will be interpreted as the bean name to be injected. You can say, it follows by-name autowiring semantics.
