关于导出数据库中的数据到EXCEL表格的setEncoding报错的问题
本人初学web开发,现在想在JSP页面中添加将数据库中的内容导入到excel表格的功能。在网上看了一些例子,其中有用poi的,我把原代码拷下来自己试,结果发现代码中报错:
Multiple markers at this line
	- The method setEncoding(short) is undefined for the type  
	 HSSFCell
	- The method setEncoding(short) is undefined for the type  
	 Object
请问这是什么原因?
完整代码如下:
package myBean;
import org.apache.poi.hssf.usermodel.*;
import java.io.*;
import java.sql.*;
import myBean.DBConnection;
public class POIExcel {
	private DBConnection con;
	public POIExcel() {
		con=new DBConnection();
	}
	//@SuppressWarnings("deprecation")
	@SuppressWarnings("deprecation")
	public void exportExcel(String name,OutputStream out){
		HSSFWorkbook wb=new HSSFWorkbook();
		HSSFSheet sheet=wb.createSheet(name);		
		HSSFRow row=sheet.createRow(0);
		HSSFCell cell=row.createCell((short)0);
		cell.setEncoding(HSSFCell.ENCODING_UTF_16);
		cell.setCellValue("姓名");		
		cell=row.createCell((short)1);
		cell.setEncoding(HSSFCell.ENCODING_UTF_16);
		cell.setCellValue("电子邮件");		
		String sql="select * from tb_contacts";
		int nRow=1;
		try{
			ResultSet rs=con.execQuery(sql);
			if(rs!=null)
			while(rs.next()){
				row=sheet.createRow(nRow++);
				cell=row.createCell((short)0);
				cell.setEncoding(HSSFCell.ENCODING_UTF_16);
				cell.setCellValue(rs.getString("name"));				
				cell=row.createCell((short)1);
				cell.setEncoding(HSSFCell.ENCODING_UTF_16);
				cell.setCellValue(rs.getString("email"));				
			}
			rs.close();
		}catch(
SQLException e){
			System.out.println("POIExcel.exportExcel()"+e.getMessage());
		}
		try{
			wb.write(out);
		}catch(Exception e){
			System.out.println("POIExcel.exportExcel()"+e.getMessage());
		}
	}
}
------解决方案--------------------
POI用的是哪版本?我用的3.6setEncoding()方法已经删掉了。
lz可以考虑换旧一点的版本
