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+";\n当前文件名:"+fileName+";\n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!
