换一种方式获取项目名称的代码：@Override 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); for (Map.Entry<String, List<TaskTask>> projectTaskEntry : projectTaskMap.entrySet()) { projectId = projectTaskEntry.getKey(); ProjectCountVO projectCountVO = new ProjectCountVO(); projectCountVO.setId(projectId); String projectName = queryAllProject.getProjectList().stream() .filter(project -> project.getId().equals(projectId)) .findFirst() .map(Project::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); }

可以尝试使用正则表达式来获取项目名称，假设项目名称是以"projectName ="开头，";"结尾的字符串，可以使用以下代码：

String regex = "projectName =([^;]*)";
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(code);
if (matcher.find()) {
    String projectName = matcher.group(1).trim();
    System.out.println("Project Name: " + projectName);
}

其中，`code`是你提供的代码字符串。这个代码会提取出第一个匹配到的项目名称。

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。

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 projectName = applicationServicePlatformClientProxy.get 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; }

请注意，你在代码中使用了变量“projectName”，但没有对其进行初始化或声明。我假设你想要从应用服务平台获取项目名称，因此你需要调用应用服务平台客户端代理的相应方法，以获取项目名称。请修改以下代码：

@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 = applicationServicePlatformClientProxy.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);
}
return result;
}
