How to use

setTaskExecutor

method

in

org.springframework.web.servlet.config.annotation.AsyncSupportConfigurer

@Override
public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
  configurer.setDefaultTimeout(2500).setTaskExecutor(new ConcurrentTaskExecutor())
    .registerCallableInterceptors(new CallableProcessingInterceptor() { })
    .registerDeferredResultInterceptors(new DeferredResultProcessingInterceptor() {});
}

  @Override
  protected void configureAsyncSupport(AsyncSupportConfigurer configurer) {
    configurer.setTaskExecutor(new ConcurrentTaskExecutor(Executors.newFixedThreadPool(3)));
    configurer.setDefaultTimeout(30000);
  }
}

@Override
public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
  configurer.setDefaultTimeout(30000);
  AsyncTaskExecutor taskExecutor = context.getBean("executor", AsyncTaskExecutor.class);
  configurer.setTaskExecutor(taskExecutor);
  super.configureAsyncSupport(configurer);
}

@Override
public void configureAsyncSupport(final AsyncSupportConfigurer configurer) {
  //处理 callable超时
  configurer.setDefaultTimeout(60*1000);
  configurer.registerCallableInterceptors(timeoutInterceptor());
  configurer.setTaskExecutor(getAsyncThreadPoolTaskExecutor());
}
