I will cover the easy way to do this in a later post, but in this post we will look at how Spring processes annotations.

Available JSR-250 Spring Annotations

The spring-beans-3.x.jar contains the package org.springframework.beans.factory.annotation. In this package you will find the following BeanPostProcessors:

• AutowiredAnnotationBeanPostProcessor
• InitDestroyAnnotationBeanPostProcessor
• QualifierAnnotationBeanPostProcessor
• RequiredAnnotationBeanPostProcesor

These PostProcessors facilitate the following annotations which can be found in the same package

• @Autowired
• @Qualifier
• @Required
