這個問題折騰了我半天，我的匯入和匯出分別用了連個poi包，這兩個包衝突，刪掉其中一個，則另一個功能就不能使用，很糾結，試了很多方法，但是我的import的工具的版本還不能換，版本必須一致，所以我決定，刪除一個版本，我的兩個版本分別位poi-3.8和poi2.2，因為poi-2.2中沒有Cell這個類，所以我刪除poi3.8我的action就會報錯，我索性刪除了poi3.8看看有沒有別的方法，把Cell刪除

	HSSFRow row = sheet.getRow(i);
				// 獲取一行每一列的資料
					HSSFCell userCodeCell = row.getCell(0);
					HSSFCell userNameCell = row.getCell(1);
					row.getCell(2).setCellType(Cell.CELL_TYPE_STRING);
					HSSFCell passWordCell = row.getCell(2);
					HSSFCell userDescriptionCell = row.getCell(3);
					HSSFCell userStateCell = row.getCell(4);
					HSSFCell superPopedomFlagCell = row.getCell(5);
					HSSFCell validStartDateCell = row.getCell(6);
					HSSFCell validEndDateCell = row.getCell(7);
					// HSSFCell pwdFlagDateCell=row.getCell(8);
					HSSFCell userEmailCell = row.getCell(8);
					String userCode = userCodeCell.getRichStringCellValue()
							.getString();
					SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
					String validStartDate = new java.text.SimpleDateFormat(
							"yyyy-MM-dd").format(validStartDateCell
							.getDateCellValue());
					String userName = userNameCell.getRichStringCellValue()
							.getString();
					String passWord = passWordCell.getRichStringCellValue()
							.getString();
					String userDescription = userDescriptionCell
							.getRichStringCellValue().getString();
					String userState = userStateCell.getRichStringCellValue()
							.getString();
					String superPopedomFlag = superPopedomFlagCell
							.getRichStringCellValue().getString();
					String validEndDate = new java.text.SimpleDateFormat(
							"yyyy-MM-dd").format(validEndDateCell
							.getDateCellValue());
					System.out.println(userCode + "--" + userName + "--"
							+ passWord + "--" + userState + "--"
							+ superPopedomFlag + "--" + validEndDate);
					String userEmail = userEmailCell.getRichStringCellValue()
							.getString();
 

這個是刪除之前的方法，修改之後====

	HSSFRow row = sheet.getRow(i);
				// 獲取一行每一列的資料
				HSSFCell planNameCell = row.getCell((short) 0);
				HSSFCell planPersonCell = row.getCell((short) 1);
				HSSFCell tierCodeCell = row.getCell((short) 2);
				HSSFCell carCodeCell = row.getCell((short) 3);
				HSSFCell planAddressCell = row.getCell((short) 4);
				HSSFCell planLevelCell = row.getCell((short) 5);
				HSSFCell planTimeCell = row.getCell((short) 6);
				// HSSFCell pwdFlagDateCell=row.getCell(8);
				HSSFCell planPictureCell = row.getCell((short) 7);
				SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
				String planTime = new java.text.SimpleDateFormat(
						"yyyy-MM-dd").format(planTimeCell
						.getDateCellValue());
				String planName =  planNameCell
						.getStringCellValue();
				String planPerson = planPersonCell
						.getStringCellValue();
				String tierCode = tierCodeCell
						.getStringCellValue();
				String carCode = carCodeCell
						.getStringCellValue();
				String planAddress = planAddressCell
						.getStringCellValue();
				String planLevel = planLevelCell
						.getStringCellValue();
				String planPicture = planPictureCell
						.getStringCellValue();

			   File fi = new File(planPicture);
			   String fileName= planPicture.substring(planPicture.lastIndexOf("\\")+1);
			   if(fi.exists()){
				   fi.mkdirs(); 
			   }
 

把Cell去掉了，換了另一種方式取值，可能新舊版本不相容，新版本有新的類加入所以只能這樣，好糾結，特寫此文，以緬情懷
