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();
      }

i already trie tu create exlusions on spring web dependency and create servlet dependecy on my maven but it doesnt work

I think that the problem is on my projectt but i dont know if it could be something on my tomcat

Solution

If you are creating a spring boot application, Tomcat server comes embedded, which means you do not need to worry about deploying your JAR/WAR file on external tomcat server. Your question seems invalid here can you elaborate more on what exactly you are trying to do ? Your POM.xml has more than required dependencies for a spring boot application to boot up !
