java讀取2003及2007版的excel

讀取excel2003需要使用apache提供的jxl.jar這個jar包：

     InputStream is = new FileInputStream(fileDir);
     jxl.Workbook rwb = Workbook.getWorkbook(is);

     Sheet rs = rwb.getSheet(0);
     int rsColumns = rs.getColumns();
     int rsRows = rs.getRows();

      if (i < rsRows) {
       for (int j = 0; j < rsColumns; j++) {
        rs.getCell(j, i).getContents();
       }
      }

 

讀取2007需要使用apache得poi包：

import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

        XSSFWorkbook xwb=new XSSFWorkbook(fileDir);
     XSSFSheet sheet=xwb.getSheetAt(0);
     XSSFRow row;
     String cell=null;
     int m=0;
     int max=0;
     for(int i=sheet.getFirstRowNum();i<sheet.getPhysicalNumberOfRows();i++)
     {
      m=sheet.getRow(i).getPhysicalNumberOfCells();
      if (m>=max) {
       max=m;
      }
      else {

      }
     }

      for(int i=sheet.getFirstRowNum();i<sheet.getPhysicalNumberOfRows();i++)
      {
       Element root_2 = new Element("columns");
       root.appendChild(root_2);
       row=sheet.getRow(i);
       for(int j=0;j<max+1;j++)
       {
        try {
         cell=row.getCell(j).toString();

        } catch (Exception e) {
         cell=null;
        }
        Element root_3 = new Element("column");
        root_3.appendChild(cell);
        root_2.appendChild(root_3);

       }
      }
      Document document = new Document(root);
      return document.toXML();
