jxl读取excel导入到数据库,报错java.lang.NoClassDefFoundError: jxl/read/biff/BiffException

Posted 2023-05-11

jxl包已经加载了

我给你一个我的例子吧：
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.*;
import java.sql.*;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import jxl.*;
public class SimUpdate
private String fileName;
public SimUpdate(String fileName)
this.fileName = fileName;

static Map tNames;
static
tNames = new HashMap();

//下面是主要代码

private void updateDb()
try
Connection conn = DbPool.connectDB();
if(conn != null)
Statement stmt = conn.createStatement();
/**********************************************/
jxl.Workbook rwb = null;
try
//构建Workbook对象 只读Workbook对象
//直接从本地文件创建Workbook
//从输入流创建Workbook
InputStream is = new FileInputStream(fileName);
rwb = Workbook.getWorkbook(is);
//Sheet(术语：工作表)就是Excel表格左下角的Sheet1,Sheet2,Sheet3但在程序中
//Sheet的下标是从0开始的
//获取第一张Sheet表
Sheet rs = rwb.getSheet(0);
//获取Sheet表中所包含的总列数
int rsColumns = rs.getColumns();
//获取Sheet表中所包含的总行数
int rsRows = rs.getRows();
//获取指这下单元格的对象引用

String simNumber = "",termSeqId = "";
//指定SIM卡号及序列号
for(int i=0;i<rsRows;i++)
for(int j=0;j<rsColumns;j++)
Cell cell = rs.getCell(j,i);
if(j==0)
simNumber = cell.getContents();//这里是猎取你要的参数，和下面一样

if(j == 1)
termSeqId = cell.getContents();


String sql = "update ....";//SQL语句
int isOk = stmt.executeUpdate(sql);
if(isOk == 0)

String insertSql = "insert....";//SQL语句
int isAdd = stmt.executeUpdate(insertSql);
if(isAdd > 0)
System.out.println("成功插入第"+i+"条数据");






//以下代码为写入新的EXCEL,这里不使用,所以注释
/*

//利用已经创建的Excel工作薄创建新的可写入的Excel工作薄
jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(new File("D://Book2.xls"),rwb);
//读取第一张工作表
jxl.write.WritableSheet ws = wwb.getSheet(0);

//获取第一个单元格对象
jxl.write.WritableCell wc = ws.getWritableCell(0, 0);
//决断单元格的类型，做出相应的转化
if (wc.getType() == CellType.LABEL)
Label l = (Label) wc;
l.setString("The value has been modified.");

//写入Excel对象
wwb.write();
wwb.close();
*/
catch(Exception e)
e.printStackTrace();

finally
//操作完成时，关闭对象，翻译占用的内存空间
rwb.close();


/*********************************************/


catch(Exception e)
e.printStackTrace();



追问

我代码没有报错啊，是运行的时候报错的。我的excel文件是wps转化的格式，不知道是不是这个的问题，然后报错那里还说我的servlet有问题，然后我重建了一下发现好像没问题。网上其他的说这个问题就是jxl包没加载，可是我加载了，不知道是什么问题。

参考技术A 你的问题解决了吗？我也遇到了一样的问题现在也没办法搞懂

springMVC jxl数据库导入Excel文件

1.新建一个jsp表单 用到multipart

  <form id="form2" method="post" enctype="multipart/form-data"     action="<%=basePath%>uploadftp.shtml">
        <input type="file" name="file">
        <input type="submit" value="ftp提交">
    </form>

2.Controller代码 ftpserver判断 然后是username判断

如果没有ftpserver添加 添加mapper中设置主键添加

useGeneratedKeys="true"和主键id对应 Conroller下面的红色代码获得主键

<insert id="addFtpServer" useGeneratedKeys="true" parameterType="ftpServerBean" keyProperty="Id">
