controller異步處理請求

1，需求場景

後臺數據處理需要多個遠程調用，數據拉取推送等IO操作很耗時或者時間預估困難，手動重新推送或拉取數據等操作。

2，處理器異步處理請求

@RestController
@RequestMapping("/pulldata")
@Slf4j
public class PullOrderController {
    @Autowired
    private TestService testService;
    /**
     * 定義任務線程池,手動處理的情況比較少，不需要太多線程數
     */
    private static ExecutorService threadPool = new ThreadPoolExecutor(1, 5, 1000, TimeUnit.MILLISECONDS, new SynchronousQueue<Runnable>(),Executors.defaultThreadFactory(),new ThreadPoolExecutor.AbortPolicy());
    /**
     * 拉取調撥單
     *
     * @param sapRequestPO
     * @return
     */
    @PostMapping(value = "test")
    public Result list(@RequestBody SapRequestPO sapRequestPO) {
        log.debug("主線程開始");
        Callable<Boolean> callable = new Callable<Boolean>() {
            @Override
            public Boolean call(){
                log.debug("副線程開始");
                boolean res = testService.pullStockOutOrderByQm(
                        sapRequestPO.getFromWho(),
                        sapRequestPO.getShopno(),
                        sapRequestPO.getSaledate(),
                        sapRequestPO.getOrderno());
                log.debug("副線程結束");
                return res;
            }
        };
        threadPool.submit(callable);
        log.debug("主線程結束");
        return Result.success();
    }
