註解掃描類,掃描的過程中會處理註解

org.springframework.context.annotation.ComponentScanAnnotationParser#parse
org.springframework.context.annotation.ClassPathBeanDefinitionScanner#doScan

以下處理Process any @Import annotations

org.springframework.context.annotation.ConfigurationClassParser#processImports

如下方法處理 @Component @PropertySources @ComponentScans @ComponentScan @ImportResource 註解

org.springframework.context.annotation.ConfigurationClassParser#doProcessConfigurationClass

如下方法處理 @Lazy @Primary @DependsOn @Role @Description 註解

org.springframework.context.annotation.AnnotationConfigUtils#processCommonDefinitionAnnotations(org.springframework.beans.factory.annotation.AnnotatedBeanDefinition, org.springframework.core.type.AnnotatedTypeMetadata)

獲取帶有@Autowired和@Value註解的屬性對象
按以下代碼流程進行註解注入

- org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory#applyMergedBeanDefinitionPostProcessors
- org.springframework.beans.factory.support.MergedBeanDefinitionPostProcessor#postProcessMergedBeanDefinition
- org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor#processInjection
- org.springframework.beans.factory.annotation.InjectionMetadata#inject
- org.springframework.beans.factory.annotation.InjectionMetadata.InjectedElement#inject
- 獲取待注入的對象org.springframework.beans.factory.annotation.InjectionMetadata.InjectedElement#getResourceToInject
- 獲取待注入的對象org.springframework.context.annotation.CommonAnnotationBeanPostProcessor.ResourceElement#getResourceToInject
- 獲取對象資源org.springframework.context.annotation.CommonAnnotationBeanPostProcessor#getResource
- 獲取帶有@Autowired和@Value註解的屬性對象org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor#findAutowiredAnnotation

獲取帶有@Component和@Value註解的屬性對象
按以下代碼流程進行註解注入
