I have written a spring boot application for file uploading. I want my spring boot application to shutdown the running localhost 8080 after its execution has been completed .

Is there any possible ways to kill the server after the spring boot execution is completed

Could someone help me on this

want to kill the localhost programmatically.

You can do this in the following way by creating a bean:

@Component
class ShutdownManager {
@Autowired
private ApplicationContext appContext;
public void initiateShutdown(int returnCode){
    SpringApplication.exit(appContext, () -> returnCode);
}

}

You can autowire this bean anywhere and use the initiateShutdown function to close teh application context and server like this:

@Component
public class Controller{
@Autowired
private final ShutdownManager shutdownManager;
  @GetMapping("/")
public void Shutdown(){
   shutdownManager.initiateShutdown(0);
}
}

Or you can simply Autowire this bean on any controller and call this method any where you want with the return code.

just put this code at end of your uploading code:

@Controller
public class Upload {

    @Autowired
    private ApplicationContext context;

    @PostMapping("/upload")
    public void uploadFile(){

    // do upload the file here.
    //after uploading shutdown the spring boot application.

    SpringApplication.exit(context, (ExitCodeGenerator) () -> 0);

       }    

     }

I have checked it myself it is working.

  • There is no need to explicitly call `System.exit`. `SpringApplication.run` returns a `ConfigurableApplicationContext` which implements `Closeable`. Once the context is closed, the application exists. So in other words: `try (ConfigurableApplicationContext context = SpringApplication.run(BlogAppApplication.class, args) { /* do nothing */ }` – Rob Spoor Oct 10 '22 at 09:04
  • Keep in mind that both will not exit at the right time, which should be after the request has been handled. – Rob Spoor Oct 10 '22 at 09:06
