Springboot戰爭部署在外部tomcat但404

我在 tomcat 上有一個專案，它可以在 spring 上運行，但是當我嘗試部署在外部 tomcat 上時，出現 404 錯誤

我已經嘗試了很多東西，但我無法解決它

我的主要課程

我看到了

@SpringBootApplication
public class RApplication extends SpringBootServletInitializer implements CommandLineRunner {
        @Resource
     // FileStorageService storageService;
        
        FileStorageService storageService;
    public static void main(String[] args) {
        SpringApplication.run(RApplication.class, args);
    }
      @Override
      protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
          return builder.sources(RApplication.class);
      }
      @Override
      public void run(String... arg) throws Exception {
        storageService.deleteAll();
        storageService.init();
      }

}

和我的 pom.xml

我已經嘗試在 spring web 依賴項上創建排除項并在我的 maven 上創建 servlet 依賴項，但它不起作用

我認為問題出在我的專案上，但我不知道它是否可能是我的 tomcat 上的問題

uj5u.com熱心網友回復：

如果您正在創建 Spring Boot 應用程式，Tomcat 服務器是嵌入式的，這意味著您無需擔心在外部 Tomcat 服務器上部署 JAR/WAR 檔案。您的問題在這里似乎無效，您能否詳細說明您到底要做什么？您的 POM.xml 具有啟動 spring boot 應用程式所需的更多依賴項！
