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：

[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！
