applyMergedBeanDefinitionPostProcessors(mbd, beanType, beanName);1、CommonAnnotationBeanPostProcessor
supports common Java annotations out of the box, in particular the JSR-250 annotations in the {@code javax.annotation} package. These common Java annotations are supported in many Java EE 5 technologies (e.g. JSF 1.2), as well as in Java 6’s JAX-WS.
This post-processor includes support for the {@link javax.annotation.PostConstruct} and {@link javax.annotation.PreDestroy} annotations - as init annotation and destroy annotation, respectively - through inheriting from {@link InitDestroyAnnotationBeanPostProcessor} with pre-configured annotation types.
The central element is the {@link javax.annotation.Resource} annotation for annotation-driven injection of named beans, by default from the containing Spring BeanFactory, with only {@code mappedName} references resolved in JNDI. The enforces JNDI lookups equivalent to standard Java EE 5 resource injection for {@code name} references and default names as well. The target beans can be simple POJOs, with no special requirements other than the type having to match。
