#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();
}

Answer 1

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 !
