Spring Batch: starting a job from within a Spring MVC contorller WITH A NEW THREAD

Question

I have a Spring-Batch job that I launch from a Spring MVC controller. The controller gets an uploaded file from the user and the job is supposed to process the file:

Answer 1

The jobLauncher.run() method can be called in a new Thread like so:

@RequestMapping(value = "/upload")
public ModelAndView uploadInventory(UploadFile uploadFile, BindingResult bindingResult) {
  [...]

  final SomeObject jobLauncher = [...]
  Thread thread = new Thread(){
    @Override
    public void run(){
      jobLauncher.run([...]);
    }
  };
  thread.start();

  return mav;
}

The thread.start() line will spawn a new thread, and then continue to execute the code below it.

Note that, if jobLauncher is a local variable, it must be declared final in order for it to be used inside of the anonymous Thread class.
