2.测试程序：
   POI程序：

    import java.io.FileInputStream;

    import java.util.Date; 

    import org.apache.poi.hssf.usermodel.HSSFWorkbook;

    import org.apache.poi.poifs.filesystem.POIFSFileSystem;

    import org.apache.poi.ss.usermodel.Cell;

    import org.apache.poi.ss.usermodel.Row;

    import org.apache.poi.ss.usermodel.Sheet;

    import org.apache.poi.ss.usermodel.Workbook;

    public class TestPOI {

        public static void read(String pathName) throws Exception {

                Workbook workbook = new HSSFWorkbook(new POIFSFileSystem(new FileInputStream(pathName)));

                Sheet sheet = workbook.getSheetAt(0); 

                int rows = sheet.getPhysicalNumberOfRows();

                for (int i = 0; i < rows; i++) { 

                        Row rowObj = sheet.getRow(i);

                        for (int j = 0; j < 4; j++) {  

                                Cell cell = rowObj.getCell(j);

                                Object content = cell.getStringCellValue(); 

                                System.out.println("i=" + i + "   j=" + j + "   " +content.toString());

                        }

                } 

        }

        public static void main(String[] args) throws Exception {

                Date date = new Date();

                long dateLong = date.getTime();

                read("D:\\TableInfoFormat.xls");

                Date date1 = new Date();

                long date1Long = date1.getTime();

                System.out.println((date1Long - dateLong) + "ms");

        } 

   }

   //JXL程序：   
   import java.io.FileInputStream;

   import java.io.InputStream;

   import java.util.Date;

   import jxl.Sheet;

   import jxl.Workbook;

   public class TestJxl {

        public static void readExcel1(String pathName) throws Exception { 

                InputStream is = new FileInputStream(pathName);

                Workbook wb = Workbook.getWorkbook(is);

                Sheet sheet = wb.getSheet(0);

                int rows = sheet.getRows(); 

                for (int i = 1; i < rows; i++) { 

                        for (int j = 0; j < 4; j++) { 

                                System.out.println("i=" + i + "   j=" + j + "   " +sheet.getCell(j, i).getContents().trim());

                        }

                }

                is.close();  

        }

        public static void main(String[] args) throws Exception{

                Date date = new Date();

                long dateLong = date.getTime();

                readExcel1("D:\\TableInfoFormat.xls");

                Date date1 = new Date();

                long date1Long = date1.getTime();

                System.out.println((date1Long - dateLong) + "ms");

        }

    }

3.测试结果

4.总结
    在小数据量时jxl快于poi，在大数据量时poi要快于jxl。但差距都不明显。
