最近在做一个项目管理的项目，主要是将用户在project文件中写的一些东西，读出来，并将其写入到数据库中。
也是借鉴了好多大佬的思想和代码，感觉自己需要整理一遍，所以，接下来就是表演的时候了。
第一步：首先创建一个实体类TaskInfo，这个类的作用就是将原本project文件中读取出的内置Task填充到自己的TaskInfo中进行处理。
还有这里用的jar包是mpxj。
package com.mammoth.entity;
import java.util.Date;
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 String parent_id; // 父任务ID
private String task_type; // 任务类型（FS,SS,FF,SF）
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 String task_start_date; // 任务开始时间
private String 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 String getParent_id() {
return parent_id;
}
public void setParent_id(String parent_id) {
this.parent_id = parent_id;
}
public String getTask_type() {
return task_type;
}
public void setTask_type(String task_type) {
this.task_type = task_type;
}
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 String getTask_name() {
return task_name;
}
public void setTask_name(String task_name) {
this.task_name = task_name;
}
public double getTask_duration() {
return task_duration;
}
public void setTask_duration(double task_duration) {
this.task_duration = task_duration;
}
public String getTask_start_date() {
return task_start_date;
}
public void setTask_start_date(String task_start_date) {
this.task_start_date = task_start_date;
}
public String getTask_finish_date() {
return task_finish_date;
}
public void setTask_finish_date(String 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;
}
@Override
public String toString() {
return "TaskInfo [project_id=" + project_id + ", task_id=" + task_id + ", task_unique_id=" + task_unique_id
+ ", parent_id=" + parent_id + ", task_type=" + task_type + ", task_outline_level=" + task_outline_level
+ ", task_name=" + task_name + ", task_duration=" + task_duration + ", task_start_date="
+ task_start_date + ", task_finish_date=" + task_finish_date + ", task_predecessors="
+ task_predecessors + ", task_operator=" + task_operator + "]";
}
} 第二步：写工具类，将mpxj jar包中的Task的对象解析出来，然后再封装到自己的TaskInfo中。
package com.mammoth.utils;
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import com.mammoth.entity.TaskInfo;
import net.sf.mpxj.MPXJException;
import net.sf.mpxj.ProjectFile;
import net.sf.mpxj.Relation;
import net.sf.mpxj.Task;
import net.sf.mpxj.mpp.MPPReader;
public class TaskUtils {
public static List<TaskInfo> readFile(){
List<TaskInfo> taskList = new ArrayList<TaskInfo>();
try{
//1. 读取文件
File file = new File("C:/Users/ruixuan/Desktop/测试project.mpp");
MPPReader mppRead = new MPPReader();
ProjectFile pf = mppRead.read(file);
//2. 拿到task对象
List<Task> tasks = pf.getAllTasks();
//3. 遍历task对象，找到其中的值
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();
//4. 获取前置任务（任务流）
StringBuilder beforeTaskId = new StringBuilder();
StringBuilder beforeTaskType = new StringBuilder();
if(task_predecessors != null){
if(task_predecessors.size() > 0){
for(Relation relation : task_predecessors){
Integer targetTaskId = relation.getTargetTask().getID();
if(beforeTaskId.length() == 0){
beforeTaskId.append(targetTaskId);
beforeTaskType.append(relation.getType());
}else{
beforeTaskId.append("," + targetTaskId);
beforeTaskType.append("," + relation.getType());
}
}
}
}
String task_predecessors_str = beforeTaskId.toString();
String task_predecessors_str_type = beforeTaskType.toString();
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
//5. 给taskinfo实体类赋值
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(format.format(task_start_date));
taskInfo.setTask_finish_date(format.format(task_finish_date));
taskInfo.setTask_predecessors(task_predecessors_str);
taskInfo.setTask_type(task_predecessors_str_type);
taskInfo.setTask_name(task.getName());
//6.自定义列读取
String task_operator = task.getText(2);
taskInfo.setTask_operator(task_operator);
taskList.add(taskInfo);
}
}catch (MPXJException e) {
return null;
} catch (Exception e) {
return null;
}
return taskList;
}
// 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();
// 初始化taskOutLineLevel
if(listSize > 2){
if(taskOutLineLevel == 1){
for(int i=listSize;i>2;i--){
tempTaskOutLine.remove(i-1);
}
listSize = 2;
}
}
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);
String 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);
String lastTaskId1 = lastMap1.get("taskId")+"";
taskInfo.setParent_id(lastTaskId1);
}else if(taskOutLineLevel < lastTaskOutLineLevel){
tempTaskOutLine.set(taskOutLineLevel, map);
Map<String,Integer> lastMap2 = tempTaskOutLine.get(taskOutLineLevel-1);
String lastTaskId2 = lastMap2.get("taskId")+"";
taskInfo.setParent_id(lastTaskId2);
}
}
}
taskList.remove(0);
return taskList;
}
} 这里的地址我测试用的是本地的一个地址，在实际开发中会在上传的时候进行解析，拿到文件流的形式即可，接下来我会写一篇关于上传解析文件的博客，也希望大佬们多多指点
第三步：测试
package com.mammoth.test;
import java.util.List;
import org.junit.Test;
import com.mammoth.entity.TaskInfo;
import com.mammoth.utils.TaskUtils;
public class TaskTest {
@Test
public void taskTest(){
// List<TaskInfo> lists = TaskUtils.readFile();
List<TaskInfo> lists = TaskUtils.refreshTaskInfo(TaskUtils.readFile());
int i = 1;
for (TaskInfo taskInfo : lists) {
System.out.println("第" + i + "次任务："+ taskInfo.toString());
i++;
}
}
}
如果可以正常运行的话，可以看到控制台打印如下内容
得到这个list集合之后 ，还不是你想干什么就干什么了。
