java中CompletableFuture.runAsync()异步代码为什么没有执行呢

java中CompletableFuture.runAsync()异步代码为什么没有执行呢?

问题相关代码

    public void robotRequestByBrand(MerchantOrderRecordDO merchantOrderRecordDO, CarBrandWmiDO carBrand) {
        //匹配机器人，获取有效的供应商【后期可以加入机器人选举策略】
        long startTimeEffective = System.currentTimeMillis();
        List<RobotEffectiveInfo> effectiveRobotList = maintenanceManager.getEffectiveRobot(carBrand, merchantOrderRecordDO);
        log.info("&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*选举的机器人的数量：" + effectiveRobotList.size());
        long endTimeEffective = System.currentTimeMillis();
        log.info("&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*选举机器人运行时间：" + (endTimeEffective - startTimeEffective) + "ms");
        alternateBrandUtilContext.saveCurrOrderBrand(merchantOrderRecordDO,carBrand);
        //异步请求机器人
        CompletableFuture.runAsync(() -> {//代码一直没有执行
            try {
                long startTime = System.currentTimeMillis();
                log.info("第三步：异步请求机器人~~," + merchantOrderRecordDO.getVin());
                maintenanceManager.syncRequestRobot(effectiveRobotList, merchantOrderRecordDO);
                long endTime = System.currentTimeMillis();
                log.info("&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*整个异步流程运行时间：" + (endTime - startTime) + "ms");
            } catch (Exception e) {
                log.info("异步请求机器人发生异常########################，vin: {}", merchantOrderRecordDO.getVin());
                e.printStackTrace();
            }
        });

        log.info("第四步：异步请求机器人完成~~，" + merchantOrderRecordDO.getVin());
    }

运行结果及报错内容

我的解答思路和尝试过的方法

我想要达到的结果

你这里主线程执行完毕，异步线程未必执行完毕。加个join()

    public void robotRequestByBrand(MerchantOrderRecordDO merchantOrderRecordDO, CarBrandWmiDO carBrand) {
        //匹配机器人，获取有效的供应商【后期可以加入机器人选举策略】
        long startTimeEffective = System.currentTimeMillis();
        List<RobotEffectiveInfo> effectiveRobotList = maintenanceManager.getEffectiveRobot(carBrand, merchantOrderRecordDO);
        log.info("&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*选举的机器人的数量：" + effectiveRobotList.size());
        long endTimeEffective = System.currentTimeMillis();
        log.info("&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*选举机器人运行时间：" + (endTimeEffective - startTimeEffective) + "ms");
        alternateBrandUtilContext.saveCurrOrderBrand(merchantOrderRecordDO,carBrand);
        //异步请求机器人
        CompletableFuture.runAsync(() -> {//代码一直没有执行
            try {
                long startTime = System.currentTimeMillis();
                log.info("第三步：异步请求机器人~~," + merchantOrderRecordDO.getVin());
                maintenanceManager.syncRequestRobot(effectiveRobotList, merchantOrderRecordDO);
                long endTime = System.currentTimeMillis();
                log.info("&*&*&*&*&*&*&*&*&*&*&*&*&*&*&*整个异步流程运行时间：" + (endTime - startTime) + "ms");
            } catch (Exception e) {
                log.info("异步请求机器人发生异常########################，vin: {}", merchantOrderRecordDO.getVin());
                e.printStackTrace();
            }
        }).join(); //等待一下
 
        log.info("第四步：异步请求机器人完成~~，" + merchantOrderRecordDO.getVin());
    }
