request.setCharacterEncoding("UTF-8");//设置request的编码方式，防止中文乱码
String fileName ="导出数据";//设置导出的文件名称
StringBuffer sb = new StringBuffer(request.getParameter("tableInfo"));//将表格信息放入内存
String contentType = "application/vnd.ms-excel";//定义导出文件的格式的字符串
String recommendedName = new String(fileName.getBytes(),"iso_8859_1");//设置文件名称的编码格式
response.setContentType(contentType);//设置导出文件格式
response.setHeader("Content-Disposition", "attachment; filename=" + recommendedName + "\"");//
response.resetBuffer();
//利用输出输入流导出文件
ServletOutputStream sos = response.getOutputStream();
sos.write(sb.toString().getBytes());
sos.flush();
sos.close();
}
