1、Java中常见的用来操做Excl的方式通常有2种：jxl和poi。java

2、两种方式区别在于：
JXL只能对Excel进行操做,属于比较老的框架，它只支持到Excel 95-2000的版本。如今已经中止更新和维护。
POI是apache的项目,可对微软的Word,Excel,Ppt进行操做,包括office2003和2007,Excl2003和2007。poi如今一直有更新。因此如今主流使用POI。sql

3、下面分别使用二者代码进行常见操做：
1.JXL数据库

public void outputExcel(HttpServletRequest request, HttpServletResponse response,String title)throws  IOException
{
    //获取输出流 
    OutputStream os = response.getOutputStream(); 
    HttpSession session=request.getSession();
    String oprator=(String)session.getAttribute("yhxm");
    //设置编码  
    response.setHeader("Content-disposition", "attachment; filename="+"cprdpxx"+".xls");// 设定输出文件头 
    request.setCharacterEncoding("utf-8");  
    //设置文件格式
    response.setContentType("application/vnd.ms-excel;charset=utf-8");
        //加标题    
    //标题字体   
    //设置单元格字体，位置
    jxl.write.WritableFont wfc = new jxl.write.WritableFont(WritableFont.COURIER, 18, WritableFont.BOLD, true);  
    jxl.write.WritableCellFormat wcfFC = new jxl.write.WritableCellFormat(wfc); 
    try {
        wcfFC.setAlignment(jxl.format.Alignment.CENTRE);
        wcfFC.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);    
        //字段字体   
        jxl.write.WritableFont wfc1 = new jxl.write.WritableFont(WritableFont.COURIER, 12, WritableFont.NO_BOLD, false,UnderlineStyle.NO_UNDERLINE, Colour.BLACK);

        //设置字体位置
        wcfFC1.setAlignment(jxl.format.Alignment.CENTRE);  
        wcfFC1.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
        //////////////////////////////////////////////

        jxl.write.WritableFont wfc3 = new jxl.write.WritableFont(WritableFont.COURIER, 14, WritableFont.BOLD, false,UnderlineStyle.NO_UNDERLINE, Colour.BLACK);

        wcfFC2.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);   
        WritableWorkbook wbook = Workbook.createWorkbook(os);  
        //设置默认字体
        WritableFont font=new WritableFont(WritableFont.COURIER, 12, WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE, Colour.BLACK);
