    测试的Excel文件为四列的普通表格

    jar包:poi-3.15-beta2.jar(Office2003xls文件)、poi-ooxml-3.15-beta2.jar(Office2007xlsx文件)

    File file=new File("D:\testEXC.xlsx");
    if(!file.exists()) {
      throw new FileNotFoundException();
    }
    FileInputStream fis = new FileInputStream(file);
                
    @SuppressWarnings("resource")
    XSSFWorkbook xssfWorkbook = new XSSFWorkbook(fis);
                
    int sheetNum = xssfWorkbook.getNumberOfSheets();
    for(int i = 0;i<sheetNum;i++) {
      Sheet sheet = xssfWorkbook.getSheetAt(i);
                    
      int lastRow = sheet.getLastRowNum();
      if(lastRow <= 0) {
        continue;
      }
                    
      Row row = null;
      String name = "";
      String title = "";
      String content = "";
      String email = "";
                    
      for(int rowNum = 1;rowNum <= lastRow;rowNum++) {
        row = sheet.getRow(rowNum);
        if(row == null) {
          continue;
        }
                        
        name = getCellValue(row.getCell(0));
        title = getCellValue(row.getCell(1));
        content = getCellValue(row.getCell(2));
        email = getCellValue(row.getCell(3));
                        
        System.out.println(name+" / "+title+" / "+content+" / "+email);
