@Controller在 Spring Boot 多模块 Maven 项目中的子包中不起作用？

poms如下；

</project>

当我运行该项目时，通过urlApiController.java可以正常工作。/app但是当我尝试访问/weburl 时WebController.java，我得到了错误页面。

否@Controller或@RestController正在使用子（网络）模块。为了解决这个问题，我添加@ComponentScan(basePackages = {"com.web"})了Application.java，但我仍然收到错误页面。

请问有什么帮助吗？提前致谢。
