Spring Boot 使用WebAsyncTask异步返回结果

@RequestMapping(value="/login", method = RequestMethod.GET)
public WebAsyncTask<ModelAndView> longTimeTask(){
  System.out.println("/login被调用 thread id is : " + Thread.currentThread().getName());
  Callable<ModelAndView> callable = new Callable<ModelAndView>() {
      public ModelAndView call() throws Exception {
        Thread.sleep(1000); /模拟长时间任务
        ModelAndView mav = new ModelAndView("login/index");
        System.out.println("执行成功 thread id is : " + Thread.currentThread().getName());
        return mav;
      }
  };
  return new WebAsyncTask<ModelAndView>(callable);
}

private AsyncTaskExecutor taskExecutor = new SimpleAsyncTaskExecutor(this.getClass().getSimpleName());

AsyncTaskExecutor executor = webAsyncTask.getExecutor();
if (executor != null) {
  this.taskExecutor = executor;
}
