springboot restcontroller not called

The problem is that my rest controller is not getting called.

@SpringBootApplication(scanBasePackages = { "com.company.base" })
public class Application {

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

@RestController
@RequestMapping("/data")
public class DataController {

    private static final Logger LOGGER = LogManager.getLogger(MethodHandles.lookup().lookupClass());

    @Autowired
    private SusbscriberRepository susbscriberRepository;

    @RequestMapping(value = "/subscribers", method = RequestMethod.GET)
    public HttpEntity<SubscriberResource> findAll() {
     ...
    }

    @RequestMapping(value = "/subscriber/{id}", method = RequestMethod.GET)
    public ResponseEntity<SubscriberResource> findSubscriber(@PathVariable(value = "id") Long id) {
      ...
    }
}

In the Springboot start log, these url are mapped.

I'm sure I'm missing something but I'm not sure what.

Even spring example is not working: gs-actuator-service-master.

Three things may have problems

  1. spring-boot-starter-tomcat & spring-boot-starter-web libs could be missing.
  2. Your controller must under the com.company.base package because of you defined scanBasePackages.
  3. Spring boot Application must run with SpringBootServletInitializer. This case will only required if your run as Java Application, that not required if you are running from mvn command.

Please add libraries & update your Application.java and try again.

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

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

}

Move controller class into subpackage of the application class. 

like 
    com.company.base for Application class
    com.company.base.controller for DataController class

then spring boot will scan controller automatically.

I faced a similar issue. I added spring-mvc dependency.

compile "org.springframework:spring-webmvc:5.1.3.RELEASE"

By default, the main class should be in the root package. I put the main class into a different package, so I had to component scan and add other components to be available.

package root.package1

@SpringBootApplication(scanBasePackages = {"root"})

public class WebAppMain {

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

Remove scanBasePackages = { "com.company.base" } if the controller is under boot app package or sub package. Or include package of main class as well in component scan.
