使用jxls技術導入Excel模版數據(轉自其他博客)

第一步：先確定好Excel導入的格式以及各表格字段值的含義

 

第二步：定義好解析的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：生成一下解析的實體類VideoInfo（這個需要根據excel文件的列去手工寫一個）

 

public class VideoInfo {
	//序號
	private int index;
	//視頻名稱（全稱）
	private String videoName;
	//視頻資源ID
	private String resourceId;
	//上傳者
	private String upload;
	//課程說明
	private String content;
	//學校名稱
	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，我這里項目用maven管理jar包的版本是1.0.6大家可以去下面這個maven資源庫下                載jar包  maven資源庫地址：http://mvnrepository.com/open-source/excel-libraries；

 

第五步：windows彈框選擇文件並解析Excel數據，這個windows文件框選擇文件我以前還是真沒做過在網上               找了一個很好用的方法請看代碼：

/**
     * 打開文件選擇窗口選擇導入文件
     * @return 返回文件路徑
     * @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){ //打開文件
            String path = jFileChooser.getSelectedFile().getAbsolutePath();
            String fileName = jFileChooser.getSelectedFile().getName();
            String extName =fileName.substring(fileName.lastIndexOf(".")+1,fileName.length());
            System.out.println("當前文件路徑："+path+";\n當前文件名："+fileName+";\n當前文件擴展名："+extName);
            if(null!=extName&&"xlsx".equals(extName)){
                return path;
            }else{
                System.out.println("您好,只能導入擴展名為xlsx的Excel文件！");
                return null;
            }
        }else{
            System.out.println("沒有選中文件");
            return null;
        }
}


/**
     * 使用jxls解析導入的Excel
     * @param path 導入文件路徑
     * @return List<VideoInfo> 導入對象集合
     */
    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讀取Excel成功！");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return videoInfoList;
    }

    其中有個靜態變量我是統一寫在配置類中的：

     public static String XML_CONFIG ="videoConfig.xml";

 

     第六步：寫一個main函數執行我們寫好的方法試一下

     

public class Test {
    public static void main(String[] args) {
        SyncDataServiceImpl syncDataService = new SyncDataServiceImpl();
        try {
            String filePath = syncDataService.getExcelPath();
            if(null!=filePath&&StringUtils.isNotBlank(filePath)){
                //導入Excel文件解析信息獲取資源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詳細信息======"+video.toString());
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

 

    其中SyncDataServiceImpl類是我把前面二個方法寫到這個類里面了，里面還有一些其他的業務處理邏輯，就不貼上來了， new SyncDataServiceImpl()對象就可以調用剛才的方法了！

相比較POI來讀取Excel數據個人覺得jxls用起來還是更方便一點！同時jxls導出Excel也是比較方便的，有自己的標簽類似JSTL，以后有時間再寫一篇吧！希望能幫到需要的人，哈哈！有寫的不對的希望高手可以指點一下！謝謝！
