修改代码“@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 QueryAllProject projectResult = applicationServicePlatformClient.listUserProject( "token", "userId", "userEnvId", "userTenant", new ProjectCondition()); QueryAllProject queryAllProject = projectResult.getData(); String projectName = queryAllProject.getBtpProjectId(); 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; }

以下是修改后的代码：

@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
        QueryAllProject projectResult = applicationServicePlatformClient.listUserProject(
                "token", "userId", "userEnvId", "userTenant", new ProjectCondition());
        QueryAllProject queryAllProject = projectResult.getData();
        String projectName = queryAllProject.getBtpProjectId();
        projectCountVO.setName(projectName);

        List<TaskTask> taskList = projectTaskEntry.getValue();
        projectCountVO.setTaskCount(taskList.size());

        Integer problemCount = 0;
        for (TaskTask task : taskList) {
            if (task.getProblemNum() != null) {
                problemCount += task.getProblemNum();
            }
        }
        projectCountVO.setProblemCount(problemCount);

        result.add(projectCountVO);
    }

    return result;
}

主要改动如下：

1. 在计算问题数时，使用了传统的循环方式遍历任务列表，避免了使用 Optional 类的连续调用；
2. 将任务数和问题数的计算分别提取到了变量中，以提高代码的可读性。
