SpringMVC源码-Autowired

@Autowired最终由AutowiredAnnotationBeanPostProcessor中的postProcessMergedBeanDefinition执行

org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor 中的postProcessMergedBeanDefinition方法 查找需要Autowired的元数据

@Override
public void postProcessMergedBeanDefinition(RootBeanDefinition beanDefinition, Class<?> beanType, String beanName) {
	if (beanType != null) {
		InjectionMetadata metadata = findAutowiringMetadata(beanName, beanType, null);
		metadata.checkConfigMembers(beanDefinition);
	}
}
