Spring @Autowired 配置

@Autowired 配置:
Spring 通过一个 BeanPostProcessor 对 @Autowired 进行解析，所以要让 @Autowired 起作用必须事先在 Spring 容器中声明 AutowiredAnnotationBeanPostProcessor Bean。

或者使用隐式注册（ 隐式注册 post-processors 包括了 AutowiredAnnotationBeanPostProcessor，CommonAnnotationBeanPostProcessor，PersistenceAnnotationBeanPostProcessor，RequiredAnnotationBeanPostProcessor。）
