spring aspect为啥要加 component

Posted 2023-03-15

参考技术A

官方文档中有写：

You may register aspect classes as regular beans in your Spring XML configuration, or autodetect them through classpath scanning - just like any other Spring-managed bean. However, note that the @Aspect annotation is not sufficient for autodetection in the classpath: For that purpose, you need to add a separate @Component annotation (or alternatively a custom stereotype annotation that qualifies, as per the rules of Spring's component scanner).

参考技术B spring 配置加了这个没有：
<!-- 使用annotation 自动注册bean,并保证@Required,@Autowired的属性被注入 -->
<context:component-scan base-package="com.evo.bpc" annotation-config="true"/>
