使用net.sf.mpxj读取project的.mpp文件

1、导入.mpp文件

public void importMppFile(String updateType, MultipartFile multipartFile) {try (InputStream inputStream = multipartFile.getInputStream()) {// 读取文件的组件MPPReader mppReader = new MPPReader();// 注意，如果在这一步出现了读取异常，肯定是版本不兼容，换个版本试试ProjectFile projectFile = mppReader.read(inputStream);// 从文件中获取的任务对象List<Task> tasks = projectFile.getChildTasks();// 解析后数据存入对象List<ProjectProgressEntity> importList = new ArrayList<>();// 递归解析方法parseTasks(tasks.get(0).getChildTasks(), new ProjectProgressEntity(), importList);} catch (Exception e) {e.printStackTrace();}}

2、递归解析任务

 /*** 递归解析任务** @param taskList               循环解析对象* @param currentProjectProgress 当前循环的数据是它的子级* @param importList             循环解析后数据存入的集合*/private static void parseTasks(List<Task> taskList, ProjectProgressEntity currentProjectProgress, List<ProjectProgressEntity> importList) {// 设置层级，如果等于空，则代表是第一层级，不为空则在父级节点的层级基础上+1int levelNum = currentProjectProgress.getPlanLevel() == null ? 1 : currentProjectProgress.getPlanLevel() + 1;// 循环所有节点for (Task task : taskList) {ProjectProgressEntity projectProgress = new ProjectProgressEntity();projectProgress.setProjectProgressId(UUID.fastUuid().toString());projectProgress.setTaskId(task.getID());projectProgress.setSerialNumber(task.getID());projectProgress.setSplitParentId(currentProjectProgress.getSerialNumber());projectProgress.setPlanLevel(levelNum);projectProgress.setTaskName(task.getName());projectProgress.setDuration(task.getDuration().getDuration());projectProgress.setPlanStartDate(task.getStart());projectProgress.setPlanEndDate(task.getFinish());projectProgress.setParentId(getParentIds(task));// 获取实际开始时间和实际结束时间的值projectProgress.setActualStartDate(task.getActualStart());projectProgress.setActualEndDate(task.getActualFinish());// 获取任务完成进度百分比projectProgress.setProgress(BigDecimal.valueOf((Double) task.getPercentageComplete()));// 获取任务的资源集合projectProgress.setPersonInCharge(MppFileUtils.getResource(task));// 获取任务状态、开始告警、结束告警的状态buildTaskStatus(task.getActualStart(), task.getActualFinish(), projectProgress);buildStartAlert(task.getStart(), task.getActualStart(), projectProgress);buildEndAlert(task.getFinish(), task.getActualFinish(), projectProgress);// 判断是否有子任务if (task.getChildTasks().size() > 0) {projectProgress.setIsNotSplit("0");// 继续进行递归，当前保存的只是父任务的信息parseTasks(task.getChildTasks(), projectProgress, importList);} else {projectProgress.setIsNotSplit("1");}importList.add(projectProgress);}}

3. 获取资源名称：MppFileUtils类的getResource方法

    /*** 获取资源名称** @param task 任务* @return 资源名称*/public static String getResource(Task task) {StringBuffer buf = new StringBuffer();List assignments = task.getResourceAssignments();for (int i = 0; i < assignments.size(); i++) {ResourceAssignment assignment = (ResourceAssignment) assignments.get(i);Resource resource = assignment.getResource();if (resource != null) {buf.append(resource.getName());// 如果不是最后一个资源，就添加逗号if (i < assignments.size() - 1) {buf.append(",");}}}return buf.toString();}

4.引入依赖：解析project的.mpp文件

        <!-- 引入依赖：解析project的.mpp文件 --><dependency><groupId>net.sf.mpxj</groupId><artifactId>mpxj</artifactId><version>10.14.1</version></dependency>
