java 读取 解析微软Project .mpp 文件到甘特图

1.引入价包;

        <dependency>
            <groupId>org.apache.poigroupId>
            <artifactId>poiartifactId>
            <version>3.15version>
        dependency>
        
        <dependency>
            <groupId>net.sf.mpxjgroupId>
            <artifactId>mpxjartifactId>
            <version>5.6.4version>
        dependency>

        <dependency>
            <groupId>net.sf.jacob-projectgroupId>
            <artifactId>jacobartifactId>
            <version>1.14.3version>
        dependency>

2.解析Task :

package com.xyy.utils;

import java.io.Serializable;
import java.util.Date;

/**
 * Created by 14258 on 2017/3/24.
 */
public class SchProjectTask implements Serializable {
    private static final long serialVersionUID = -3323529750871923312L;
    /**
     * uuid
     */
    private String id;
    /**
     * 编号id
     */
    private String recordId;
    /**
     * 唯一id
     */
    private String uniqueId;
    /**
     * 父节点编号
     **/
    private String parentId;
    /**
     * 任务名称
     **/
    private String name;
    /**
     * 大纲水平
     */
    private Integer level;
    /**
     * 工期
     **/
    private Number duration;
    /**
     * 工期单位
     */
    private String durationTimeUnit;
    /**
     * 开始时间
     **/
    private Date startTime;
    /**
     * 结束时间
     **/
    private Date finishTime;
    /**
     * 完成百分比
     **/
    private Number percentageComplete;
    /**
     * 前置任务
     **/
    private String predecessors;
    /**
     * 所属项目文件id
     */
    private String ProId;

    //这里写set和get
    //这里写toStirng方法

}

3.要读取的文件的名字和作者,版本号

package com.xyy.utils;

import java.io.Serializable;

/**
 * Created by 14258 on 2017/3/24.
 */
public class SchProject implements Serializable {

    private static final long serialVersionUID = -3611636937880845938L;

    /**
     * uuid
     */
    private String id;
    /**
     * 文件名字
     */
    private String name;
    /**
     * 版本号 默认0
     */
    private Integer version;
    /**
     * 作者
     */
    private String author;

    //这里写set和get

    //这里写toStirng方法
}

4.使用自己写的工具类读取

package com.xyy.utils;
