Question

I want to save zip archive from server to user computer. I have web page that shows some information about this file and has a download button. In my controller action on button simply redirect on homepage but I want to get data from database and save it to user machine with path is defined by user

The issue is that I don’t know how I can get this path. Could you give me an example how I can do that?

Answer 1

In your controller method you can add this code to get file download

File file = new File("fileName");
FileInputStream in = new FileInputStream(file);
byte[] content = new byte[(int) file.length()];
in.read(content);
ServletContext sc = request.getSession().getServletContext();
String mimetype = sc.getMimeType(file.getName());
response.reset();
response.setContentType(mimetype);
response.setContentLength(content.length);
response.setHeader("Content-Disposition", "attachment; filename=\"" + file.getName() + "\"");
org.springframework.util.FileCopyUtils.copy(content, response.getOutputStream());
