数据导入到excel 并显示在页面

完全用jxl包




首先写java文件


package com.test.excel;




import java.io.*;


import jxl.*;


import jxl.write.*;


import jxl.format.*;


import java.util.*;


import java.awt.Color;






public class TestExcel ...{




public static void writeExcel(OutputStream os) throws Exception ...{


WritableWorkbook wwb = Workbook.createWorkbook(os);


WritableSheet ws = wwb.createSheet("TestSheet1", 0);


Label labelC = new Label(0, 0, "哈哈");


ws.addCell(labelC);


WritableFont wfc = new WritableFont(WritableFont.ARIAL,20, WritableFont.BOLD, false,


UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.GREEN);


WritableCellFormat wcfFC = new WritableCellFormat(wfc);


wcfFC.setBackground(jxl.format.Colour.RED);


labelC = new Label(4, 1, "gagaga呷呷机阿姐阿",wcfFC);


ws.addCell(labelC);






for(int i = 5;i<9;i++)...{ //循环操作写单元格




for(int j=0;j<4;j++)...{


labelC = new Label(j, i, i+""+j);


ws.addCell(labelC);


}


}




// 写入Exel工作表


wwb.write();


// 关闭Excel工作薄对象


wwb.close();


}




// 最好写一个这样的main方法来测试一下你的这个class是否写好了。




public static void main(String[] args)throws Exception...{


File f=new File("kk.xls");


f.createNewFile();


writeExcel(new FileOutputStream(f));


}




}




然后在页面显示：


excel，jsp


<%@page import="com.test.excel.TestExcel" %>


<%


response.reset();


response.setContentType("application/vnd.ms-excel");


TestExcel.writeExcel(response.getOutputStream());


%>
