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

可以通过在线的mpp阅读工具打开的，该工具免费，但限制了上传文件大小不超过2M。

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。

MPXJ官方网站：http://mpxj.sourceforge.net

MPXJ官方API说明文档：http://mpxj.sourceforge.net/apidocs/index.html

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<Relation> 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<TaskInfo> readInputStream(InputStream in,String fileName){

List<TaskInfo> taskList = new ArrayList<TaskInfo>();
InputStream ins = in;

try{
MPPReader mppRead = new MPPReader();
ProjectFile pf = mppRead.read(in);
logger.info("MPXJUtils.method [readInputStream]: fileName-" + fileName);

List<Task> 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<Relation> 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
java.sql.Date sqlFinishDate = Str2Date.getUKDate(task_finish_date.toString());              // FinishDate转换
StringBuffer sb = new StringBuffer();
if(task_predecessors != null){
if(task_predecessors.size() > 0){
for(Relation relation : task_predecessors){
Integer targetTaskId = relation.getTargetTask().getID();
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_unique_id(task_unique_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);
return null;
} finally {
try {
ins.close();
} catch (IOException e) {
// TODO Auto-generated catch block
logger.info("MPXJUtils.method [readInputStream]: IOException-" + e);
return null;
}
}
return taskList;
}

封装过的TaskInfo

public class TaskInfo {

private int project_id;                         // 所属项目ID
private int task_id;                            // 任务ID
private int task_unique_id;                     // 任务唯一ID
private int parent_id;                          // 父任务ID
private int task_outline_level;                 // 任务级别
private String task_name;                       // 任务名称
private double task_duration;                   // 任务工期
private java.sql.Date task_start_date;          // 任务开始时间
private java.sql.Date task_finish_date;         // 任务结束时间
private String task_predecessors;               // 任务流
private String task_operator;                   // 负责人

public int getProject_id() {
return project_id;
}
public void setProject_id(int project_id) {
this.project_id = project_id;
}
public int getTask_id() {
return task_id;
}
public void setTask_id(int task_id) {
this.task_id = task_id;
}
public int getTask_unique_id() {
return task_unique_id;
}
public void setTask_unique_id(int task_unique_id) {
this.task_unique_id = task_unique_id;
}
public int getParent_id() {
return parent_id;
}
public void setParent_id(int parent_id) {
this.parent_id = parent_id;
}
public int getTask_outline_level() {
return task_outline_level;
}
public void setTask_outline_level(int task_outline_level) {
this.task_outline_level = task_outline_level;
}
public double getTask_duration() {
return task_duration;
}
public void setTask_duration(double task_duration) {
this.task_duration = task_duration;
}
public Date getTask_start_date() {
return task_start_date;
}
public void setTask_start_date(Date task_start_date) {
this.task_start_date = task_start_date;
}
public Date getTask_finish_date() {
return task_finish_date;
}
public void setTask_finish_date(Date task_finish_date) {
this.task_finish_date = task_finish_date;
}
public String getTask_predecessors() {
return task_predecessors;
}
public void setTask_predecessors(String task_predecessors) {
this.task_predecessors = task_predecessors;
}
public String getTask_operator() {
return task_operator;
}
public void setTask_operator(String task_operator) {
this.task_operator = task_operator;
}
public String getTask_name() {
return task_name;
}
public void setTask_name(String task_name) {
this.task_name = task_name;
}
}

解析本地mpp文件方法，供测试使用

public static List<TaskInfo> readFile(){

List<TaskInfo> taskList = new ArrayList<TaskInfo>();
try{
File file = new File("/Users/ffff/Downloads/计划（含月度版）V0.10-20160222.mpp");
MPPReader mppRead = new MPPReader();
ProjectFile pf = mppRead.read(file);
logger.info("MPXJUtils.method [readFile]: fileName-" + file.getName());

List<Task> 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();
Date task_start_date = task.getStart();
Date task_finish_date = task.getFinish();
List<Relation> task_predecessors = task.getPredecessors();
logger.info("MPXJUtils.method [readFile] 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
java.sql.Date sqlFinishDate = Str2Date.getUKDate(task_finish_date.toString());          // FinishDate转换
StringBuffer sb = new StringBuffer();
if(task_predecessors != null){
if(task_predecessors.size() > 0){
for(Relation relation : task_predecessors){
Integer targetTaskId = relation.getTargetTask().getID();
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_unique_id(task_unique_id);
taskInfo.setTask_outline_level(task_outline_level);
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 [readFile]: MPXJException-" + e);
return null;
} catch (Exception e) {
logger.info("MPXJUtils.method [readFile]: MPXJException-" + e);
return null;
}
return taskList;
}

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<TaskInfo> refreshTaskInfo(List<TaskInfo> taskList){

List<Map<String,Integer>> tempTaskOutLine = new ArrayList<Map<String,Integer>>();
for(TaskInfo taskInfo : taskList){

int taskId = taskInfo.getTask_id();
int taskOutLineLevel = taskInfo.getTask_outline_level();
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<String,Integer> map = new HashMap<String,Integer>();
map.put("taskId", taskId);
map.put("taskOutLineLevel", taskOutLineLevel);

if(listSize == 0){

if(taskOutLineLevel == 0){
tempTaskOutLine.add(map);
}else{
return null;
}

}else{

Map<String,Integer> lastMap = tempTaskOutLine.get(listSize-1);
int lastTaskId = lastMap.get("taskId");
int lastTaskOutLineLevel = lastMap.get("taskOutLineLevel");

if(taskOutLineLevel > lastTaskOutLineLevel){

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

tempTaskOutLine.set(taskOutLineLevel, map);

Map<String,Integer> lastMap1 = tempTaskOutLine.get(taskOutLineLevel-1);
int lastTaskId1 = lastMap1.get("taskId");
taskInfo.setParent_id(lastTaskId1);
}else if(taskOutLineLevel < lastTaskOutLineLevel){

tempTaskOutLine.set(taskOutLineLevel, map);

Map<String,Integer> lastMap2 = tempTaskOutLine.get(taskOutLineLevel-1);
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。
