Java download csv file content-disposition

Assuming you got the HttpServletResponse you can do something like this to stream a file. This way the file will be saved into clients' machine. And the stream method should be like this. What this does is, get an inputstream from your source file and write that stream into the outputstream of the HttpServletResponse. But note that this will break if the filename contains non "token" characters, such as whitespace, non-ASCII, and certain delimiters.

Avoid code-only answers. Provide some explanations about the snippet! Beware, if the filename is not properly sanitized, this solution can lead to an easy cross-site-scripting attack!

I started this blog as a place to share everything I have learned in the last decade. I write about modern JavaScript, Node. Get an HTTP trace and show us all of the response header fields. I ran into this problem earlier tonight and none of the other suggestions in this thread worked. In my case it was an XLSX file to be downloaded. All browsers except Firefox seem to work just fine. I am also using Spring MVC as you appear to be. Add a comment.

I was running into this problem earlier tonight and tried applying the double-quote fix as you suggested, although it didn't make any difference.

Even if I am not sure why it worked, changing the addHeader Method to setHeader fixed the issue. I'm pretty sure that the trailing ": " in the header name parameter is incorrect.
