1、mpp文件介绍
MPP是Microsoft Project项目管理软件的文件扩展名,此软件旨在帮助个人跟踪,组织或维护项目。
2、mpp显示效果
3、mpp结构说明
通过上图可以看出，文件主体内容就是一条一条的记录，记录内容包括：任务ID、任务名、Duration、Start日期、Finish日期、Predecessors业务流、自定义字段。
接下来，我们先来了解下mpp文档的解析工具类，目前主要是通过MPXJ工具类来解析该文件。
Package net.sf.mpxj.mpp
上面这个包是处理MPP文件解析的主要集合，通过net.sf.mpxj.mpp.MPPReader类来构建读文件管道。
每条具体的任务都需要通过这个类net.sf.mpxj.Task来解析。
// 普通任务ID
Integer task_id =task.getID();
// 独立任务ID
Integer task_unique_id =task.getUniqueID();
// 大纲ID
Integer task_outline_level =task.getOutlineLevel();
// 任务周期
double task_duration =task.getDuration().getDuration();
// 任务名
String task_name = task.getName();
// 任务开始日期
Date task_start_date = task.getStart();
// 任务结束日期
Date task_finish_date = task.getFinish();
// 任务流
List task_predecessors = task.getPredecessors();
4、mpp解析代码
解析线上mpp文件,同时获取TaskInfo
// NO.1 解析mpp文件,同时获取TaskInfo
public static List readInputStream(InputStream in,String fileName){
List taskList = new ArrayList();
InputStream ins = in;
try{
MPPReader mppRead = new MPPReader();
ProjectFile pf = mppRead.read(in);
logger.info("MPXJUtils.method [readInputStream]: fileName-" + fileName);
List tasks = pf.getAllTasks();
logger.info("MPXJUtils.method [readInputStream]: taskSize-" + tasks.size());
for (int i = 0; i < tasks.size(); i++) {
Task task = tasks.get(i);
Integer task_id = task.getID();
Integer task_unique_id = task.getUniqueID();
Integer task_outline_level = task.getOutlineLevel();
double task_duration = task.getDuration().getDuration();
String task_name = task.getName();
Date task_start_date = task.getStart();
Date task_finish_date = task.getFinish();
List task_predecessors = task.getPredecessors();
logger.info("MPXJUtils.method [readInputStream] taskInfo:" + task_id + "|" + task_unique_id + "|" + task_outline_level + "|" + task_duration + "|" + task_start_date + "|" + task_finish_date + "|" + task_predecessors);
// 封装TaskInfo
java.sql.Date sqlStartDate = Str2Date.getUKDate(task_start_date.toString()); // StartDate转换

StringBuffer sb = new StringBuffer();
if(task_predecessors != null){

if(sb.length() == 0){
sb.append(targetTaskId);
}else{
sb.append(","+targetTaskId);
}
}
}
}
String task_predecessors_str = sb.toString(); // 任务流文本
TaskInfo taskInfo = new TaskInfo();
taskInfo.setTask_id(task_id);

taskInfo.setTask_outline_level(task_outline_level);
taskInfo.setTask_name(task_name);
taskInfo.setTask_duration(task_duration);
taskInfo.setTask_start_date(sqlStartDate);
taskInfo.setTask_finish_date(sqlFinishDate);
taskInfo.setTask_predecessors(task_predecessors_str);
taskList.add(taskInfo);
}
}catch (MPXJException e) {
logger.info("MPXJUtils.method [readInputStream]: MPXJException-" + e);
return null;
} catch (Exception e) {
logger.info("MPXJUtils.method [readInputStream]: MPXJException-" + e);

ins.close();
} catch (IOException e) {
// TODO Auto-generated catch block

解析本地mpp文件方法，供测试使用
public static List readFile(){
List taskList = new ArrayList();
try{

ProjectFile pf = mppRead.read(file);
logger.info("MPXJUtils.method [readFile]: fileName-" + file.getName());
List tasks = pf.getAllTasks();
logger.info("MPXJUtils.method [readFile]: taskSize-" + tasks.size());
for (int i = 0; i < tasks.size(); i++) {
Task task = tasks.get(i);
Integer task_id = task.getID();
Integer task_unique_id = task.getUniqueID();
Integer task_outline_level = task.getOutlineLevel();
double task_duration = task.getDuration().getDuration();

本地测试，输出mpp文件结果：
获取子任务间的所属父子关系
// NO.2 获取TaskInfo之间的父子关联关系
public static List refreshTaskInfo(List taskList){
List> tempTaskOutLine = new ArrayList>();
for(TaskInfo taskInfo : taskList){
int taskId = taskInfo.getTask_id();

int listSize = tempTaskOutLine.size();
logger.info("MPXJUtils.method [refreshTaskInfo1]: taskId-" + taskId + ",taskOutLineLevel-" + taskOutLineLevel + ",listSize-" + listSize);
// 初始化taskOutLineLevel
if(listSize > 2){
if(taskOutLineLevel == 1){
for(int i=listSize;i>2;i--){
tempTaskOutLine.remove(i-1);
}
listSize = 2;
logger.info("MPXJUtils.method [refreshTaskInfo2]: taskId-" + taskId + ",taskOutLineLevel-" + taskOutLineLevel + ",listSize-" + listSize);
}
}
Map map = new HashMap();
map.put("taskId", taskId);
map.put("taskOutLineLevel", taskOutLineLevel);
if(listSize == 0){
if(taskOutLineLevel == 0){

int lastTaskOutLineLevel = lastMap.get("taskOutLineLevel");
if(taskOutLineLevel > lastTaskOutLineLevel){

taskInfo.setParent_id(lastTaskId);
}else if(taskOutLineLevel == lastTaskOutLineLevel){
tempTaskOutLine.set(taskOutLineLevel, map);

taskInfo.setParent_id(lastTaskId1);
}else if(taskOutLineLevel < lastTaskOutLineLevel){
tempTaskOutLine.set(taskOutLineLevel, map);

int lastTaskId2 = lastMap2.get("taskId");
taskInfo.setParent_id(lastTaskId2);
}
}
}
return taskList;
}
5、数据存储
将解析的结果，经过子任务排序，即获取每条子任务的父任务，大家可以理解为书本目录的大纲。
下面看看数据存储到数据库后的效果：
