调用“@Resource private ApplicationServicePlatformClientProxy applicationServicePlatformClientProxy;”获取“projectName"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(projectTaskMap.get(projectId)).map(taskList -> taskList.get(0).getName()).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; }

可以改成这样：

@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.getProjectById(projectId)).map(ProjectVO::getName).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;
}

其中，我们使用 `applicationServicePlatformClientProxy` 的 `getProjectById` 方法获取项目名称，并将其赋值给 `projectName` 变量。同时，我们将原来代码中的 `projectId` 参数改为局部变量，避免在循环中修改参数值带来的问题。
