jsp excel數據 添加到 數據庫表中

準備：jxl.jar,jspsmartupload.jar 兩個包 excel表格

1.上傳excel獲得路徑

SmartUpload su=new SmartUpload();

su.initialize(this.getServletConfig(), request, response);
try {
su.upload();
String strname=su.getFiles().getFile(0).getFileName();
String abPath=this.getServletContext().getRealPath("/kejian");
//3.設定允許上傳的文件(通過擴展名限制)，僅允許doc、txt文件.  
su.setAllowedFilesList("xls");  
            //4.設定禁止上傳的文件(通過擴展名限制)，禁止上傳帶有exe、bat、jsp、htm、html擴展名的文件和沒有擴展名的文件  
            su.setDeniedFilesList("ext,bat,jsp,htm,html,txt,doc,pdf,,");
String filepath=abPath+File.separator+strname;
su.getFiles().getFile(0).saveAs(filepath);

escelTeachStu(filepath);
request.getRequestDispatcher("teacher/excelupload.jsp").forward(request, response);


} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}




}
//通過excel路徑獲得數據並寫到數據庫
public void escelTeachStu(String filepath){
 
try {
Workbook book = Workbook.getWorkbook(new File(file));
Sheet sheet  =  book.getSheet( 0 );
 int rows = sheet.getRows();
 int cols = sheet.getColumns();
 TeachStuImp st=new TeachStuImp();
 for (int x = 1; x <rows; x++) {
 List<String>list=new ArrayList<String>();
  for (int j = 0; j < cols; j++) {
  Cell xy = sheet.getCell(j, x);
      list.add(xy.getContents());

  }

// 將數據插入數據庫表

  TeachStu am=new TeachStu(list.get(0),list.get(1),list.get(2));
  st.add(am);
 }
} catch (BiffException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
