## 类 SimpleBeanDefinitionRegistry

- java.lang.Object
- - org.springframework.core.SimpleAliasRegistry
  - - org.springframework.beans.factory.support.SimpleBeanDefinitionRegistry

- 所有已实现的接口:
    BeanDefinitionRegistry, org.springframework.core.AliasRegistry

      public class SimpleBeanDefinitionRegistry
      extends org.springframework.core.SimpleAliasRegistry
      implements BeanDefinitionRegistry

  Simple implementation of the `BeanDefinitionRegistry` interface. Provides registry capabilities only, with no factory capabilities built in. Can for example be used for testing bean definition readers.
