用java代码遍历excel文件并回显

今天需要完成282个指标,分析后发现好多都是可复用的字段和方法,生成的dao类也是很多重复的代码,所以写下了简单的自动化遍历excel的test方法, excel业务逻辑如下,用了

HSSFSheet

类来实现,并复习了一遍

public static void main(String[] args) {
      // TODO Auto-generated method stub
      try {
            FileInputStream fStream = new FileInputStream("E:/开发文档/中台迁移表数据/新增指标.xls");//修改
            HSSFWorkbook book = new HSSFWorkbook(fStream);
            
          //获得第一个工作表对象(ecxel中sheet的编号从0开始,0,1,2,3,....)
          HSSFSheet sheet = book.getSheet("Sheet1");
          StringBuilder sb = FuncUtils.getStringBuilder();
