jkd8用法

--多线程处理

  CompletableFuture<Object> future2 = ThreadUtil.supplyAsyncWithContext(() -> {

            // 进行中 状态的活动

            getAndUpdateCurrentNextAccounts(currentNextAccountList, userId, roleMap, userCNMap);

            return null;

        });

        checkAndUpdateToNullAccount(toNullList);

        CompletableFuture allQuery = CompletableFuture.allOf(future1, future2);

        allQuery.join();

 

        ProjectInstance projectInstance = projectInstanceService.getById(projectId);

        recursionHandler(projectInstance, projectActivityVOS, userCNMap);

--多线程supplyAsync

CompletableFuture<Object> baseFormFuture = CompletableFuture.supplyAsync(() -> {

ApplicationContextHelper.setApplicationContextUser();

// 查询基本信息

return mouldAcceptancePreviewService.getBaseCard(queryVo);

        }, ThreadPoolFactory.EXECUTOR);

--CompletableFuture.supplyAsync取值

List<CompletableFuture<Object>> instancesFutureList = instanceVOS.stream()

.map(item -> CompletableFuture.supplyAsync(() -> {

ApplicationContextHelper.setRequestContextHolder(currentUser);

queryBaseForm(item.getInstanceId(), supplierCode, pId, instanceSet);

return null;

}, ThreadPoolFactory.EXECUTOR))

.collect(Collectors.toList());

instancesFutureList.stream().map(CompletableFuture::join).collect(Collectors.toList());

--list 取字段值

List<String>delIds=drawingList.stream().map(DeleteObjectInput::getId).collect(Collectors.toList());

-- list to map

Map<String, PartVO> partMap =

                parts.stream().collect(Collectors.toMap(PartVO::getNumber, item -> item, (k1, k2) -> k2));

-- mybatisplus取值

List<StringvalueData>stringValueDatas=

stringvalueDataService.list(Wrappers.<StringvalueData>lambdaQuery()

.in(StringvalueData::getInstanceTypeId,

problemInstances.stream().map(ProblemInstance::getId).collect(Collectors.toList()))

.in(StringvalueData::getAttributeName,Arrays.asList(ProblemConstants.NEXT_PROCCESSOR)));

-- mybatisplus取值

List<SupplierTask>supplierTasks=supplierTaskService.list(

Wrappers.<SupplierTask>lambdaQuery().eq(SupplierTask::getInstanceCode,pboNumber)

.eq(SupplierTask::getSupplierCode,supplierCode));
