多线程技术优化：Callable，FutureTask，Task.get()

Map<String,BaseResultMessage> brmMap = new HashMap<>();
        long beginTimeSum = System.currentTimeMillis();
        for(StkInventoryWlTypeEnum emum:StkInventoryWlTypeEnum.values()){
            long beginTime = System.currentTimeMillis();
            Callable<BaseResultMessage> aCallable =()->{
                if (OrgNumberEunm.FA_FJ.getOrgNumber().equals(stkInventoryWlDto.getOrg())) {
                    return stkInventoryWlServicemap.get(emum.getCode()).getStkInventoryWlFq(stkInventoryWlDto);

                } else {
                    return stkInventoryWlServicemap.get(emum.getCode()).getStkInventoryWlHn(stkInventoryWlDto);
                }
            };
            FutureTask<BaseResultMessage> aCallableTask = new FutureTask(aCallable);
            new Thread(aCallableTask,emum.getName()+"|线程|"+emum.getCode()).start();
            brmMap.put(emum.getName()+"["+emum.getCode()+"]",aCallableTask.get());//花时在等待（解决方案：Map<String,FutureTask> callableTaskGetMap = new HashMap<>();，主线程走完后再取aCallableTask.get()）

long endTime = System.currentTimeMillis(); 
logger.info("花时："+emum.getName()+"["+emum.getCode()+"]"+((endTime-beginTime))+"ms"); 
} 
long endTimeSum = System.currentTimeMillis(); 
logger.info("总合计-花时："+((endTimeSum-beginTimeSum))+"ms");

加一个callableTaskGetMap用来存数据，FutureTask键值：减少等待时间aCallableTask.get()
 Map<String,FutureTask> callableTaskGetMap = new HashMap<>();
====================================================

Map<String, Object> brmMap = new HashMap<>();
        Map<String,FutureTask> callableTaskGetMap = new HashMap<>();
        long beginTimeSum = System.currentTimeMillis();
