java - 关闭 org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping detectorHandlers

Question

如何关闭 org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping detectorHandlers ，我将 spring 3 启动置于 Debug模式，并且我看到所有类都调用“detectHandlers”

示例

[org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping detectHandlers org.springframework.web.servlet.handler.AbstractDetectingUrlHandlerMapping.detectHandlers(AbstractDetectingUrlHandlerMapping.java:86)] - Rejected bean name 'org.springframework.security.authenticationManager': no URL paths identified

[org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping detectHandlers org.springframework.web.servlet.handler.AbstractDetectingUrlHandlerMapping.detectHandlers(AbstractDetectingUrlHandlerMapping.java:86)] - Rejected bean name 'systemProperties': no URL paths identified

[org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping detectHandlers org.springframework.web.servlet.handler.AbstractDetectingUrlHandlerMapping.detectHandlers(AbstractDetectingUrlHandlerMapping.java:86)] - Rejected bean name 'systemEnvironment': no URL paths identified

只有我的“ Controller ”类有处理程序，而所有其他类都没有。我正在努力加快 Spring 启动速度。无论如何要关闭每个类的自动检测处理程序功能吗？

Answer 1

不必要的类(class)可以跳过using filters :

<beans>

   <context:component-scan base-package="org.example">
      <context:exclude-filter type="regex" expression=".*NotControllerBean"/>
   </context:component-scan>

</beans>

对我来说最高效、最清晰的解决方案是将 Controller 移至专用包并仅使用此包进行组件扫描。
