Spring源码分析之Scope注解处理

前言

本文旨在分析在Spring容器启动之时，@Scope注解的处理过程。

处理代码为：

ScopeMetadata scopeMetadata = this.scopeMetadataResolver.resolveScopeMetadata(abd);
abd.setScope(scopeMetadata.getScopeName());//进入this.scopeMetadataResolver.resolveScopeMetadata方法
ScopeMetadata resolveScopeMetadata(BeanDefinition definition);//找到resolveScopeMetadata(BeanDefinition definition)方法的实现如下：@Overridepublic ScopeMetadata resolveScopeMetadata(BeanDefinition definition) {ScopeMetadata metadata = new ScopeMetadata();if (definition instanceof AnnotatedBeanDefinition) {AnnotatedBeanDefinition annDef = (AnnotatedBeanDefinition) definition;AnnotationAttributes attributes = AnnotationConfigUtils.attributesFor(annDef.getMetadata(), this.scopeAnnotationType);if (attributes != null) {metadata.setScopeName(attributes.getString("value"));ScopedProxyMode proxyMode = attributes.getEnum("proxyMode");if (proxyMode == ScopedProxyMode.DEFAULT) {proxyMode = this.defaultProxyMode;}metadata.setScopedProxyMode(proxyMode);}}return metadata;}
