用org.apache.poi将Excel里的数据导入数据库

       将Excel里的数据导入到数据库，使用的是apache开发的POI jar包。思路很简单：读出Excel中所需要的数据--拼接成sql语句--导入即可。直接贴代码

package com.hwxx.utils;

import java.io.FileInputStream;
import java.io.IOException;
import java.sql.*;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRichTextString;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;



public class Excel2SqlServer {
	private static Connection conn;
	private static Statement stmt;
	private static String url ="jdbc:sqlserver://localhost:1433;DatabaseName=xxxxxx";
	private static String classforname="com.microsoft.sqlserver.jdbc.SQLServerDriver";
	private static String uid = "sa";
	private static String pwd = "xxxxxx";
	
	//执行插入sql语句
	private static void insert(String sql){
		try {
			ResultSet rs=null;
			stmt.execute(sql);
			 rs = stmt.getResultSet();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	//解析Excel文件，拼接成sql语句
	@SuppressWarnings("unused")
	private static void insertSql(){
		try{
			//获取Excel的文件流
			POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream("D:/dfly.xls"));
			HSSFWorkbook wb = new HSSFWorkbook(fs);
			//选择Excel文件中的第3个sheet子表
			HSSFSheet sheet = wb.getSheetAt(3);
			
			HSSFRow row = null;
			String sql;
			
			//sheet.getLastRowNum()为最后一行
			for(int i=1;i<=sheet.getLastRowNum();i++){
				
				//从第i行开始
				row = sheet.getRow(i);
				
				//获取i行中的某个单元格的值
				HSSFCell cell = row.getCell(2);			 
				cell.setCellType(cell.CELL_TYPE_STRING);
				HSSFRichTextString richStr = cell.getRichStringCellValue();
				String deptname = richStr.toString();
				
				cell = row.getCell(3);
				cell.setCellType(cell.CELL_TYPE_STRING);
				richStr = cell.getRichStringCellValue();
				String username = richStr.toString();

				cell.setCellType(cell.CELL_TYPE_STRING);
				richStr = cell.getRichStringCellValue();
				String mailnum = richStr.toString();
				
				cell = row.getCell(8);
				cell.setCellType(cell.CELL_TYPE_STRING);
				richStr = cell.getRichStringCellValue();
				String remark = richStr.toString();
				
				//拼接sql语句
				sql =  "insert into hltp_employee(delete_flag,username,password,homephone,email,remark) values('N','"+username +"','123456','"+ telnum +"','"+ mailnum+"','"+ remark+"')" ;
				insert(sql);
			}
		}catch(IOException e){
