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：
[java] view plain copy
- /**
- * 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
[java] view plain copy
- 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！
