double projectName = Double.valueOf(item2.getProjectName()) + Double.valueOf(item.getProjectName());这行代码提示input String"-" 该怎么改

如果出现了"input String"的提示，说明item2.getProjectName()或item.getProjectName()的返回值中包含了非数字的字符，例如“-”，所以无法将其转换为double类型。

为了解决这个问题，可以先对每个返回值进行校验，确保其只包含数字和小数点，再进行转换，例如：

String projectName1 = item2.getProjectName();
String projectName2 = item.getProjectName();
if (projectName1 != null && projectName1.matches("^[0-9.]+$") && projectName2 != null && projectName2.matches("^[0-9.]+$")) {
    double projectName = Double.valueOf(projectName1) + Double.valueOf(projectName2);
    // 进一步处理
} else {
    // 处理输入不合法的情况
}

其中，`matches("^[0-9.]+$")`表示校验字符串是否只包含数字和小数点。如果不符合要求，则需要进行相应的处理。

要将下载的文件字体设置为仿宋，你需要在导出Word文档之前，将文档中的字体样式修改为仿宋。可以参考以下代码：

// 渲染表格
List<Map<String, Object>> jobs = new ArrayList<>();
Map<String, Object> job;
for (int i = 0; i < projectCalculateResultList.size(); i++) {
    job = new HashMap<>();
    job.put("id", i+1);
    job.put("zxbz", projectCalculateResultList.get(i).getDecoration());
    job.put("jsjd", projectCalculateResultList.get(i).getFamilyProperty());
    BigDecimal projectRent = projectCalculateResultList.get(i).getProjectRent().setScale(2, BigDecimal.ROUND_HALF_UP);
    job.put("projectRent", projectRent);
    // 设置字体为仿宋
    XWPFRun run = (XWPFRun)job.get("projectRent");
    run.setFontFamily("仿宋");
    jobs.add(job);
}
params.put("jobs", jobs);

// 导出word
WordUtils.exportWordDoc(doc, temDir, fileName, params, request, response);

在上述代码中，我添加了一行代码来设置表格中"projectRent"字段的字体为仿宋。请确保系统中存在仿宋字体。这样，在导出的Word文档中，"projectRent"字段的字体将被设置为仿宋。

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; }

@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).getProjectName()).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;
