关于poi导出excel的问题...

[andy2011_yang]

String outputFile="F://test.xls";
...
...
...中间是创建workbook
...
...
// 新建一输出文件流
FileOutputStream fOut = new FileOutputStream(outputFile);
// 把相应的Excel 工作簿存盘
workbook.write(fOut);
fOut.flush();
// 操作结束，关闭文件
fOut.close();

这样的话直接是把生成的excel保存到了outputFile="F://test.xls";下面，那怎么让它弹出一“打开，保存，取消”这样的选择框 ，可以选择下载到自己需要的路径下面...？

尝试着直接读取字符串

应该是要用response获取输出流吧

网上搜一下，下载的例子很多，你对照一个改改，就可以了。

[andy2011_yang]

response.setContentType("application/x-msdownload;charset=gbk");

response.setContentLength((int) fileSize);
contentDisposition = contentDisposition != null ? contentDisposition : "attachment;";

response.setHeader("Content-Disposition", contentDisposition + " filename=" + new String(destFileName.getBytes("GBK"), "8859_1"));

response.setHeader("Content-Type", MimeUtil.getMIME(destFileName));
response.setHeader("Expires", "10000");
response.setHeader("Content-Length", String.valueOf(fileSize));

int k = 0;
if (bufferSize <= 0)
bufferSize = FILE_BUFFER_SIZE;
OutputStream ostream = response.getOutputStream();
byte buffer[] = new byte[bufferSize];
while ((long) k < fileSize) {
int j = istream.read(buffer, 0, bufferSize);
k += j;
ostream.write(buffer, 0, j);
}

谁能给我注释一下呢...现在HSSFWorkbook是workbook已经拿到 怎么写..？
