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; }

您需要将代码中的“projectName”替换为您要使用的变量名称，例如“name”：

@Resource 
private ApplicationServicePlatformClientProxy applicationServicePlatformClientProxy;

@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 name = Optional.ofNullable(projectTaskMap.get(projectId)).map(taskList -> taskList.get(0).getName()).orElse(""); 
    projectCountVO.setName(name); 
    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; 
}
