如何使用Java中的Spring MVC实现文件下载？

Question

There is a lot upload examples, but I couldn't find any for download. I'm using Spring 3.0 and I need to generate some text buffer and then let user download it as a file. (There is no static resource.)

So far I've tried to use @ResponseBody and writing to response output stream. In both cases browser display content of the 'file' instead of showing Save dialog box. How do I make browser display a dialog box?

Thanks.

您必须在操作中设置Content-Disposition标头（而不仅仅是响应主体）：

Content-Disposition: attachment; filename=your-file.pdf
