java – 在服务器崩溃/关闭后恢复Asynch ThreadPoolTask??execut

我有一个 Spring rest控制器,它使用Spring的@Async方法调用异步方法,并立即向客户端返回一个http 202代码(Accepted).(异步作业很重,可能导致超时).
实际上,在异步任务结束时,我正在向客户发送一封电子邮件,告诉他他的请求的状态.

一切正常,但我问自己,如果我的服务器/ jvm崩溃或者它关闭了我该怎么办？我的客户将收到202代码,永远不会收到状态电子邮件.

有没有办法在数据库中甚至在文件中同步(实时)ThreadPoolTask??Executor,让服务器在启动时恢复而不用自己管理复杂规则和进化状态？

这是我的Executor配置

@Configuration
@EnableAsync
public class AsyncConfig implements AsyncConfigurer {

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(4);
        executor.setMaxPoolSize(8);
        executor.setQueueCapacity(100);
        executor.setThreadNamePrefix("asyncTaskExecutor-");
        executor.setAwaitTerminationSeconds(120);
        executor.setKeepAliveSeconds(30);
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new SimpleAsyncUncaughtExceptionHandler();
    }

}

启动异步任务的控制器

@RequestMapping(value = "/testAsync",method = RequestMethod.GET)
public void testAsync() throws InterruptedException{
    businessService.doHeavyThings();
}

异步方法调用：

@Async
public void doHeavyThings() throws InterruptedException {

    LOGGER.error("Start doHeavyThings with configured executor - " + Thread.currentThread().getName() + " at " + new Date());
    Thread.sleep(5000L);
    LOGGER.error("Stop doHeavyThings with configured executor - " + Thread.currentThread().getName() + " at " + new Date());
}

}

谢谢
