检查下面代码并打印：public List<ProjectCountVO> projectCount(String beginTime, String endTime, Integer forceType, String projectId) { // 查询任务列表 List<TaskTask> taskTaskList = this.listStatisticsTask(beginTime, endTime, forceType, projectId); if (CollectionUtil.isEmpty(taskTaskList)) { return Collections.emptyList(); } List<ProjectCountVO> result = new ArrayList<>(); // 将任务按照项目ID分组 Map<String, List<TaskTask>> projectTaskMap = taskTaskList.stream().collect(Collectors.groupingBy(TaskTask::getProjectId)); //查询项目名称 String bspToken = RequestHeaderHolder.getBspToken(); String bspUserId = RequestHeaderHolder.getUserId(); String bspUserEnvId = RequestHeaderHolder.getCompanyId(); String bspUserTenant = RequestHeaderHolder.getCompanyId(); String companyId = RequestHeaderHolder.getCompanyId(); ProjectCondition projectCondition = new ProjectCondition(); projectCondition.setAppId("23031408164321600"); projectCondition.setCompanyId(companyId); projectCondition.setDesignStatusList(Arrays.asList(2,3)); projectCondition.setPageSize(-1); projectCondition.setUserId(bspUserId); QueryAllProject queryAllProject = applicationServicePlatformClientProxy.listUserProject( bspToken, bspUserId, bspUserEnvId, bspUserTenant, projectCondition); // 遍历项目及对应的任务列表 for (Map.Entry<String, List<TaskTask>> projectTaskEntry : projectTaskMap.entrySet()) { projectId = projectTaskEntry.getKey(); ProjectCountVO projectCountVO = new ProjectCountVO(); projectCountVO.setId(projectId); String projectName = queryAllProject.getName(); projectCountVO.setName(projectName); List<TaskTask> taskList = projectTaskEntry.getValue(); projectCountVO.setTaskCount(taskList.size()); Integer problemCount = CollectionUtil.isEmpty(taskList) ? 0 : taskList.stream().collect(Collectors.summingInt(task -> Optional.ofNullable(task.getProblemNum()).orElse(0))); projectCountVO.setProblemCount(problemCount); result.add(projectCountVO); } return result; }

这段代码的作用是查询一段时间内指定项目的任务数量和问题数量，并按项目分组返回结果。具体来说，它做了以下几个步骤：

1. 调用 listStatisticsTask 方法查询任务列表；
2. 将任务列表按照项目 ID 分组；
3. 调用 applicationServicePlatformClientProxy 的 listUserProject 方法查询项目信息；
4. 遍历项目及对应的任务列表，计算任务数量和问题数量，并将结果封装成 ProjectCountVO 对象加入到结果列表中；
5. 返回结果列表。

但是在代码中有一个问题：在遍历项目及对应的任务列表时，虽然获取了项目 ID，但是没有通过项目 ID 查询到对应的项目名称。因此，需要在遍历项目列表前先调用 listUserProject 方法查询项目信息，然后根据项目 ID 获取对应的项目名称。

通过接口“applicationServicePlatformClient”在下面代码中调用projectname并打印代码：public List<ProjectCountVO> projectCount(String beginTime, String endTime, Integer forceType, String projectId) { List<TaskTask> taskTaskList = this.listStatisticsTask(beginTime, endTime, forceType, projectId); if(CollectionUtil.isEmpty(taskTaskList)){ return Collections.emptyList(); } List<ProjectCountVO> result = new ArrayList<>(); Map<String, List<TaskTask>> projectTaskMap = taskTaskList.stream().collect(Collectors.groupingBy(TaskTask::getProjectId)); for (Map.Entry<String, List<TaskTask>> projectTaskEntry : projectTaskMap.entrySet()) { projectId = projectTaskEntry.getKey(); ProjectCountVO projectCountVO = new ProjectCountVO(); projectCountVO.setId(projectId); //查询项目名称List<TaskTask> taskList = projectTaskEntry.getValue(); projectCountVO.setTaskCount(taskList.size()); Integer problemCount = CollectionUtil.isEmpty(taskList) ? 0 : taskList.stream().collect(Collectors.summingInt(task-> Optional.ofNullable(task.getProblemNum()).orElse(0))); projectCountVO.setProblemCount(problemCount); result.add(projectCountVO); } return result; }

您可以这样调用projectname并打印代码：

public List<ProjectCountVO> projectCount(String beginTime, String endTime, Integer forceType, String projectId) {
    List<TaskTask> taskTaskList = this.listStatisticsTask(beginTime, endTime, forceType, projectId);
    if(CollectionUtil.isEmpty(taskTaskList)){
        return Collections.emptyList();
    }

    List<ProjectCountVO> result = new ArrayList<>();
    Map<String, List<TaskTask>> projectTaskMap = taskTaskList.stream().collect(Collectors.groupingBy(TaskTask::getProjectId));

    for (Map.Entry<String, List<TaskTask>> projectTaskEntry : projectTaskMap.entrySet()) {
        projectId = projectTaskEntry.getKey();
        ProjectCountVO projectCountVO = new ProjectCountVO();
        projectCountVO.setId(projectId);
        
        // 查询项目名称
        String projectName = applicationServicePlatformClient.getProjectName(projectId);
        projectCountVO.setName(projectName);

        List<TaskTask> taskList = projectTaskEntry.getValue();
        projectCountVO.setTaskCount(taskList.size());
        Integer problemCount = CollectionUtil.isEmpty(taskList) ? 0 : taskList.stream().collect(Collectors.summingInt(task-> Optional.ofNullable(task.getProblemNum()).orElse(0)));
        projectCountVO.setProblemCount(problemCount);
        result.add(projectCountVO);
    }
    System.out.println("projectname: " + projectId);
    return result;
}

在for循环中，我们使用项目ID调用`applicationServicePlatformClient`的`getProjectName`方法，获取项目名称并设置到`ProjectCountVO`对象中。最后，在方法结束前打印`projectId`的值。

检查并修改下面代码：@Override public List<ProjectCountVO> projectCount(String beginTime, String endTime, Integer forceType, String projectId) { List<TaskTask> taskTaskList = this.listStatisticsTask(beginTime, endTime, forceType, projectId); if(CollectionUtil.isEmpty(taskTaskList)){ return Collections.emptyList(); } List<ProjectCountVO> result = new ArrayList<>(); Map<String, List<TaskTask>> projectTaskMap = taskTaskList.stream().collect(Collectors.groupingBy(TaskTask::getProjectId)); for (Map.Entry<String, List<TaskTask>> projectTaskEntry : projectTaskMap.entrySet()) { projectId = projectTaskEntry.getKey(); ProjectCountVO projectCountVO = new ProjectCountVO(); projectCountVO.setId(projectId); //查询项目名称 String projectName = Optional.ofNullable(applicationServicePlatformClientProxy.queryProjectName(projectId)); projectCountVO.setName(projectName); List<TaskTask> taskList = projectTaskEntry.getValue(); projectCountVO.setTaskCount(taskList.size()); Integer problemCount = CollectionUtil.isEmpty(taskList) ? 0 : taskList.stream().collect(Collectors.summingInt(task-> Optional.ofNullable(task.getProblemNum()).orElse(0))); projectCountVO.setProblemCount(problemCount); result.add(projectCountVO); } return result; }

@Override
public List<ProjectCountVO> projectCount(String beginTime, String endTime, Integer forceType, String projectId) {
List<TaskTask> taskTaskList = this.listStatisticsTask(beginTime, endTime, forceType, projectId);
if (CollectionUtil.isEmpty(taskTaskList)) {
return Collections.emptyList();
}

List<ProjectCountVO> result = new ArrayList<>();
Map<String, List<TaskTask>> projectTaskMap = taskTaskList.stream().collect(Collectors.groupingBy(TaskTask::getProjectId));
for (Map.Entry<String, List<TaskTask>> projectTaskEntry : projectTaskMap.entrySet()) {
projectId = projectTaskEntry.getKey();
ProjectCountVO projectCountVO = new ProjectCountVO();
projectCountVO.setId(projectId);
//查询项目名称
String projectName = Optional.ofNullable(applicationServicePlatformClientProxy.queryProjectName(projectId)).orElse("");
projectCountVO.setName(projectName);
List<TaskTask> taskList = projectTaskEntry.getValue();
projectCountVO.setTaskCount(taskList.size());
Integer problemCount = CollectionUtil.isEmpty(taskList) ? 0 : taskList.stream().collect(Collectors.summingInt(task -> Optional.ofNullable(task.getProblemNum()).orElse(0)));
projectCountVO.setProblemCount(problemCount);
result.add(projectCountVO);
}
return result;
}

修改说明：

1. 在查询项目名称时，应该在 Optional.ofNullable() 后面加上 orElse("")，以避免 projectName 为空时出现 NullPointerException。
2. 对于 Optional.ofNullable(task.getProblemNum()).orElse(0) 这一行代码，建议加上括号以提高可读性。
