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();
}
}

}
