使用jxls技术导入Excel模版数据(转自其他博客)

第一步：先确定好Excel导入的格式以及各表格字段值的含义

第二步：定义好解析的XML--videoConfig.xml

<?xml version="1.0" encoding="UTF-8"?> 
<workbook> 
   <worksheet name="Sheet1"> 
    <section startRow="0" endRow="0"/> 
    <loop startRow="1" endRow="1" items="videoInfoList" var="videoInfo" varType="com.iflytek.weike.job.bo.VideoInfo"> 
    <section startRow="1" endRow="1"> 
    <mapping row="1" col="0">videoInfo.index</mapping> 
    <mapping row="1" col="1">videoInfo.videoName</mapping> 
    <mapping row="1" col="2">videoInfo.resourceId</mapping> 
    <mapping row="1" col="3">videoInfo.upload</mapping> 
    <mapping row="1" col="4">videoInfo.content</mapping> 
    <mapping row="1" col="5">videoInfo.schoolName</mapping>
   </section> 
    <loopbreakcondition> 
     <rowcheck offset="0">
        <cellcheck offset="0"></cellcheck> 
      </rowcheck> 
    </loopbreakcondition> 
    </loop> 
    </worksheet> 
</workbook>

 第三步：生成一下解析的实体类VideoInfo（这个需要根据excel文件的列去手工写一个）

public class VideoInfo {
	//序号
	private int index;
	//视频名称（全称）
	private String videoName;
	//视频资源ID
	private String resourceId;
	//上传者
	private String upload;
	//课程说明
	private String content;
	//学校名称
	private String schoolName;
	
	public VideoInfo() {
	}
	public VideoInfo(int index, String videoName, String resourceId, String upload, String content, String schoolName) {
		super();
		this.index = index;
		this.videoName = videoName;
		this.resourceId = resourceId;
		this.upload = upload;
		this.content = content;
		this.schoolName = schoolName;
	}
	public int getIndex() {
		return index;
	}
	public void setIndex(int index) {
		this.index = index;
	}
	public String getVideoName() {
		return videoName;
	}
	public void setVideoName(String videoName) {
		this.videoName = videoName;
	}
	public String getResourceId() {
		return resourceId;
	}
	public void setResourceId(String resourceId) {
		this.resourceId = resourceId;
	}
	public String getUpload() {
		return upload;
	}
	public void setUpload(String upload) {
		this.upload = upload;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}
	public String getSchoolName() {
		return schoolName;
	}
	public void setSchoolName(String schoolName) {
		this.schoolName = schoolName;
	}
	@Override
	public String toString() {
		return "VideoInfo [index=" + index + ", videoName=" + videoName + ", resourceId=" + resourceId + ", upload="
				+ upload + ", content=" + content + ", schoolName=" + schoolName + "]";
	}
	
	
}

 
 第四步：添加jxls的jar包，我这里项目用maven管理jar包的版本是1.0.6大家可以去下面这个maven资源库下                载jar包  maven资源库地址：http://mvnrepository.com/open-source/excel-libraries；

第五步：windows弹框选择文件并解析Excel数据，这个windows文件框选择文件我以前还是真没做过在网上               找了一个很好用的方法请看代码：

/**
     * 打开文件选择窗口选择导入文件
     * @return 返回文件路径
     * @throws Exception
     */
    public String getExcelPath() throws Exception{
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        JFileChooser jFileChooser=new JFileChooser();
        int i = jFileChooser.showOpenDialog(null);
        if(i== jFileChooser.APPROVE_OPTION){ //打开文件
            String path = jFileChooser.getSelectedFile().getAbsolutePath();
            String fileName = jFileChooser.getSelectedFile().getName();
            String extName =fileName.substring(fileName.lastIndexOf(".")+1,fileName.length());
            System.out.println("当前文件路径："+path+";
当前文件名："+fileName+";
当前文件扩展名："+extName);
            if(null!=extName&&"xlsx".equals(extName)){
                return path;
            }else{
                System.out.println("您好,只能导入扩展名为xlsx的Excel文件！");
                return null;
            }
        }else{
            System.out.println("没有选中文件");
            return null;
        }
}


/**
     * 使用jxls解析导入的Excel
     * @param path 导入文件路径
     * @return List<VideoInfo> 导入对象集合
     */
    public List<VideoInfo> getExcelDataForVideoInfo(String path){
        List<VideoInfo> videoInfoList = new ArrayList<VideoInfo>();
        try {
            InputStream inputXML = new BufferedInputStream(getClass().getClassLoader().getResourceAsStream(ConsForSystem.XML_CONFIG));
            XLSReader mainReader = ReaderBuilder.buildFromXML( inputXML );
            InputStream inputXLS = new BufferedInputStream(new FileInputStream(new File(path)));
            VideoInfo videoInfo = new VideoInfo();
            Map<String,Object> beans = new HashMap<String,Object>();
            beans.put("videoInfo", videoInfo);
            beans.put("videoInfoList", videoInfoList);
            XLSReadStatus readStatus = mainReader.read( inputXLS, beans);
            if(readStatus.isStatusOK()){
                System.out.println("jxls读取Excel成功！");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return videoInfoList;
    }

    其中有个静态变量我是统一写在配置类中的：

     public static String XML_CONFIG ="videoConfig.xml";

     第六步：写一个main函数执行我们写好的方法试一下

     

public class Test {
    public static void main(String[] args) {
        SyncDataServiceImpl syncDataService = new SyncDataServiceImpl();
        try {
            String filePath = syncDataService.getExcelPath();
            if(null!=filePath&&StringUtils.isNotBlank(filePath)){
                //导入Excel文件解析信息获取资源id
                List<VideoInfo> infoList = syncDataService.getExcelDataForVideoInfo(filePath);
                System.out.println("infoList大小==="+infoList.size());
                for(VideoInfo video:infoList){
                    System.out.println("打印ideoInfo详细信息======"+video.toString());
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

    其中SyncDataServiceImpl类是我把前面二个方法写到这个类里面了，里面还有一些其他的业务处理逻辑，就不贴上来了， new SyncDataServiceImpl()对象就可以调用刚才的方法了！

 下面的运行截图：

 

 

 运行结果截图，导入Excel成功：

 
相比较POI来读取Excel数据个人觉得jxls用起来还是更方便一点！同时jxls导出Excel也是比较方便的，有自己的标签类似JSTL，以后有时间再写一篇吧！希望能帮到需要的人，哈哈！有写的不对的希望高手可以指点一下！谢谢！
