public List<TaskTask> listStatisticsTask(String beginTime, String endTime, Integer forceType, String projectId){ List<TaskTask> taskList = taskTaskService.listStatisticsTask(beginTime, endTime, forceType, projectId); if(CollectionUtil.isEmpty(taskList)){ return Collections.emptyList(); } if(ConstantUtils.ONE.equals(forceType)){ List<RuleContent> forceRuleContentList = modelCheckRuleClientProxy.getForceRuleContentList(); if (CollectionUtil.isEmpty(forceRuleContentList)){ return Collections.emptyList(); } return this.filterTaskIdOfForceRuleContent(taskList, forceRuleContentList.stream().map(RuleContent::getRuleContentId).collect(Collectors.toList())); } return taskList; }

这段代码看起来是一个 Java 方法，接收四个参数：beginTime、endTime、forceType 和 projectId，返回一个 TaskTask 类型的列表。在方法内部，它首先调用了 taskTaskService 的 listStatisticsTask 方法获取任务列表。如果任务列表为空，会返回一个空列表。如果 forceType 的值为 1，它会调用 modelCheckRuleClientProxy 的 getForceRuleContentList 方法获取强制规则内容列表。如果强制规则内容列表为空，也会返回一个空列表。最后，会调用 filterTaskIdOfForceRuleContent 方法，过滤出符合强制规则内容列表中规则的任务，返回过滤后的任务列表。如果 forceType 不为 1，直接返回任务列表。

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。
