java代码实现excel输到导入oracle

1.首先需要两个jar包jxl.jar,ojdbc.jar（注意版本，版本不合适会报版本错误）
2.代码

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
/**
 * excel数据导入到oracle
 * @author sh
 * 2010-05-11
 */
public class InsertData {
	public static void main(String[] args) throws Exception {

		InsertData in = new InsertData();
		in.insert("F:/myJob/hah.xls","information");

	}

	/**
	 * 
	 * @param path
	 *            要解析的excel文件路径
	  * @param dataTable
	 *            要写入到数据库中的表名          
	 * @throws BiffException
	 * @throws IOException
	 */
	public void insert(String path,String dataTable) throws BiffException, IOException {
		
		File file = new File(path); 		
		// 创建新的Excel 工作簿
		Workbook rwb = null;
		rwb = Workbook.getWorkbook(file);
		
		// 得到工作簿中的第一个表索引即为excel下的sheet1,sheet2,sheet3...
		Sheet sheet = rwb.getSheets()[0];
		int rsColumns = sheet.getColumns();// 列数
		int rsRows = sheet.getRows();// 行数
		String simNumber = "" ;//每个单元格中的数据
		
		DBUtils jdbc=new DBUtils();
		
		String str="";//拼接要插入的列
			for (int j = 0; j <rsColumns; j++) {
				Cell cell = sheet.getCell(j, 0);
				simNumber = cell.getContents();
				if(j==rsColumns-1){
					str +=  simNumber  ;
				}else{
					str +=  simNumber+",";
				}
				
			}
		for (int i = 1; i < rsRows; i++) {
			
			String sql = "insert into "+dataTable+"("+str+") values(";//拼接sql
			System.out.println(str);
			for (int j = 0; j < rsColumns; j++) {
				Cell cell = sheet.getCell(j, i);
				simNumber = cell.getContents();
				if(j==rsColumns-1){
					sql += "'"+ simNumber+"'" ;
				}else{
					sql +="'"+ simNumber+"',";
				}
				
			}
			sql += " )";
			jdbc.executeUpdate(sql);//执行sql
			
		}
		jdbc.closeStmt();
		jdbc.closeConnection();
	}

}
