How to download files using spring MVC in Java?

2020-08-02 • Java

There are many upload examples, but I can't find any downloads I'm using spring 3.0. I need to generate some text buffers and let users download them as files (no static resources.)

So far, I have tried to use @ ResponseBody and write the response output stream In both cases, the browser displays the contents of the file instead of the save dialog box How do I make my browser display dialog boxes?

thank you.

Solution

You must set the content disposition header (not just the response body) in the operation:

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