context：annotation-config

annotation-config is a Spring Framework annotation that is used to enable the processing of Spring annotations within a Spring application context. When this annotation is used in a Spring configuration class, Spring will automatically detect and register beans that are annotated with @Component, @Service, @Repository, @Controller, and other related annotations. This makes it easier to manage the configuration of Spring beans in a Spring application, as it eliminates the need to manually configure bean definitions in XML configuration files. The annotation-config feature is a part of Spring's support for annotation-based configuration, which is an alternative to XML-based configuration.

context:annotation-config

"annotation-config" 是 Spring 框架中的一个配置选项，用于启用对基于注解的配置的支持。当在 Spring 的 XML 配置文件中包含该选项时，Spring 将扫描指定包下的所有组件，并自动为其中使用了特定注解的类创建对应的 bean 实例。这些注解包括 @Component、@Service、@Controller、@Repository 等。使用 "annotation-config" 可以使 Spring 框架更加方便地实现基于注解的配置和依赖注入。

<context:annotation-config />

< context:annotation-config / > 是一个Spring框架的配置元素，用于启用注解的处理器和注解的解析器。这个配置元素可以让Spring自动扫描所有的注解，并将它们转换为相应的Bean定义和Bean。这样就可以使用注解来代替繁琐的XML配置文件，并且使代码更容易维护和阅读。
