Web service stopped working after deploy

Question

It works locally on localhost. Tried to deploy on Heroku and AWS. Doesn't work. But static resources are ok. Response is 404.

@SpringBootApplication
@RestController
public class WebService implements WebServiceInterface{

    public static void main(String[] args) throws Throwable {
        SpringApplication.run(WebService.class, args);
    }

    @Override
    @RequestMapping("/getcontent")
    public WebContent getContent(@RequestParam(value="id", defaultValue="summary") String id) {
        try {
            return new WebContent(id);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    } }

1. Locally I used

   mvn spring-boot:run

That's why I had no problem with my web service

2. For Heroku and AWS I deployed war package. It didn't work for my code. Only this initializer helped to solve my problem:

    public class ServletInitializer extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(Application.class); } }
