需要下載 jxl-2.6.10.jar

 

public class ImportExcelUnits {
 
 public static List<Object[]> readExcel(File file, int beginIndex) throws Exception{   // beginIndex 重第幾行開始解析

     // 將每列的數據存入結果集中
     result.add(tempData);
    }
   }
  } catch (Exception e) {
   throw new Exception("解析Excel表格出錯..\n" + e.getMessage());
  }
  return result;
 }
 

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