由于HSSFWorkbook只能操作excel2003一下版本,XSSFWorkbook只能操作excel2007以上版本，所以利用Workbook接口創建對應的對象操作excel來處理兼容性

@Test
public void test6() throws Exception{
HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream( new File("c://123.xls")));
HSSFSheet sheet = workbook.getSheetAt(0);
HSSFRow row =sheet.getRow(0);
HSSFCell cell= row.getCell(0);
System.out.println(cell.toString());
}

@Test
public void test7() throws Exception{
XSSFWorkbook workbook = new XSSFWorkbook(new FileInputStream( new File("c://456.xlsx")));
XSSFSheet sheet = workbook.getSheetAt(0);
XSSFRow row =sheet.getRow(0);
XSSFCell cell= row.getCell(0);
System.out.println(cell.toString());
}

@Test //利用Workbook接口和判斷excel版本創建相應版本HSSFWorkbook/XSSFWorkbook對象
public void test8() throws Exception{
String file = "c://456.xlsx";
boolean isExcel2003 = file.toLowerCase().endsWith("xls")?true:false;
Workbook workbook = null;
if(isExcel2003){
workbook = new HSSFWorkbook(new FileInputStream(new File(file)));
}else{
workbook = new XSSFWorkbook(new FileInputStream(new File(file)));
}
Sheet sheet = workbook.getSheetAt(0);
Row row =sheet.getRow(0);
Cell cell= row.getCell(0);
System.out.println(cell.toString());
}
