@Component-scan是Spring框架中的一个注解,它的作用是自动扫描指定包下的所有类,将带有特定注解的类注册为Spring容器中的Bean。这样,我们就可以使用@Autowired等注解来自动注入这些Bean,而不需要手动配置Bean的定义。@Component-scan可以大大简化Spring应用程序的配置,提高开发效率。

context:component-scan

springMVC context:component-scan
The <context:component-scan> element in Spring MVC is used to scan the classpath for annotated components (such as controllers, services, repositories, and configuration classes) and automatically register them with the Spring application context.
This element defines a base package to start scanning for annotated components. It can also be used to exclude certain packages or classes from scanning.
For example, the following XML configuration scans the com.example package for annotated components:
<context:component-scan base-package="com.example"/>
This element is often used in conjunction with other Spring MVC configuration elements, such as <mvc:annotation-driven> and <bean> definitions.
