How to set ‘Content-Disposition’ and ‘Filename’ when using FileSystemResource to force a file download file?

In addition to the accepted answer, Spring has the class ContentDisposition specific for this purpose. I believe it deals with the file name sanitization.

      ContentDisposition contentDisposition = ContentDisposition.builder("inline")
          .filename("Filename")
          .build();

      HttpHeaders headers = new HttpHeaders();
      headers.setContentDisposition(contentDisposition);
