| - refresh() -> invokeBeanFactoryPostProcessors()
- ConfigurationClassPostProcessor.postProcessBeanDefinitionRegistry()
- ConfigurationClassPostProcessor.processConfigBeanDefinitions()
- 1.parser.parse(candidates)比如此时candidates是SpringApplication启动类
- ConfigurationClassParser.parse()
- 1.不同类型的 beanDefinition,调用不同的 parse(),parse()方法 -> processConfigurationClass()
- 2.this.deferredImportSelectorHandler.process() 处理入口
- ConfigurationClassParser.DeferredImportSelectorHandler.process()
- 1.创建 DeferredImportSelectorGroupingHandler
- 2.deferredImports排序
- 3.deferredImports注册
- 4.handler.processGroupImports(); // 处理
- ConfigurationClassParser.DeferredImportSelectorGroupingHandler#processGroupImports()
- 1.遍历groupings.values(),调用grouping.getImports()
- ConfigurationClassParser.DeferredImportSelectorGrouping#getImports()
- 1.this.group.process()
- AutoConfigurationImportSelector.AutoConfigurationGroup#process()
- 1.getAutoConfigurationEntry(getAutoConfigurationMetadata(),annotationMetadata)
- AutoConfigurationImportSelector#getAutoConfigurationEntry()
- 1.isEnabled(annotationMetadata)判断ENABLED_OVERRIDE_PROPERTY属性,是否启用自动配置
- 2.getCandidateConfigurations(): 通过 spi 加载 spring.factories 里所有的 AutoConfiguration 配置类
- 3.removeDuplicates() 移除重复配置
- 4.getExclusions(): exclusions处理
- 5.filter(): 遍历AutoConfigurationImportFilter类,做filter处理
- 6.fireAutoConfigurationImportEvents(): 发布AutoConfigurationImportEvent事件
- 2.this.group.selectImports()
- AutoConfigurationImportSelector.AutoConfigurationGroup#selectImports() 做排序并返回
- 2.processImports()
- ConfigurationClassParser#processImports():就是ConfigurationClassParser里类对@Import注解的处理逻辑
