到这里配置类的主要解析流程就已经结束了，接下来回到解析之后的流程
处理@Import导入的beanDefintion和配置类中的@Bean this.reader.loadBeanDefinitions(configClasses); public void loadBeanDefinitions(Set<ConfigurationClass> configurationModel) { TrackedConditionEvaluator trackedConditionEvaluator = new TrackedConditionEvaluator(); //循环刚刚解析过的所有配置类 for (ConfigurationClass configClass : configurationModel) { loadBeanDefinitionsForConfigurationClass(configClass, trackedConditionEvaluator); } } private void loadBeanDefinitionsForConfigurationClass( ConfigurationClass configClass, TrackedConditionEvaluator trackedConditionEvaluator) { if (trackedConditionEvaluator.shouldSkip(configClass)) { String beanName = configClass.getBeanName(); if (StringUtils.hasLength(beanName) && this.registry.containsBeanDefinition(beanName)) { this.registry.removeBeanDefinition(beanName); } this.importRegistry.removeImportingClass(configClass.getMetadata().getClassName()); return; } // 将Import注解引入的class注册到容器的BeanDefinitionMap中 if (configClass.isImported()) { registerBeanDefinitionForImportedConfigurationClass(configClass); } for (BeanMethod beanMethod : configClass.getBeanMethods()) { //将beanMethod转化成BeanDefinition注册到容器的beanDefinitionMap中 loadBeanDefinitionsForBeanMethod(beanMethod); } loadBeanDefinitionsFromImportedResources(configClass.getImportedResources()); //调用在解析Import时放入的ImportBeanDefinitionRegistrar的registerBeanDefinitions方法 loadBeanDefinitionsFromRegistrars(configClass.getImportBeanDefinitionRegistrars()); } 摘取处理BeanMethod逻辑如下 private void loadBeanDefinitionsForBeanMethod(BeanMethod beanMethod) { ConfigurationClass configClass = beanMethod.getConfigurationClass(); MethodMetadata metadata = beanMethod.getMetadata(); String methodName = metadata.getMethodName(); //解析出方法上@Bean注解的所有属性值 AnnotationAttributes bean = AnnotationConfigUtils.attributesFor(metadata, Bean.class); //创建一个ConfigurationClassBeanDefinition，标识为通过@Bean注解注册的bean ConfigurationClassBeanDefinition beanDef = new ConfigurationClassBeanDefinition(configClass, metadata); beanDef.setSource(this.sourceExtractor.extractSource(metadata, configClass.getResource())); //以下逻辑为拿出@Bean中的属性填充到BeanDefinition中，最后注册容器中 beanDef.setAutowireMode(AbstractBeanDefinition.AUTOWIRE_CONSTRUCTOR); //解析注解填充属性 AnnotationConfigUtils.processCommonDefinitionAnnotations(beanDef, metadata); Autowire autowire = bean.getEnum("autowire"); if (autowire.isAutowire()) { beanDef.setAutowireMode(autowire.value()); } boolean autowireCandidate = bean.getBoolean("autowireCandidate"); if (!autowireCandidate) { beanDef.setAutowireCandidate(false); } String initMethodName = bean.getString("initMethod"); if (StringUtils.hasText(initMethodName)) { beanDef.setInitMethodName(initMethodName); } String destroyMethodName = bean.getString("destroyMethod"); beanDef.setDestroyMethodName(destroyMethodName); //将创建的BeanDefinition注册到容器中 this.registry.registerBeanDefinition(beanName, beanDefToRegister); }
