maybe the `encoded` text is actually the `pdf` contents, try setting the `Content-Type:` — Scary Wombat, Aug 16 '16 at 05:04
@ScaryWombat solved yeah encoded text was content of pdf file. i tried this method headers.setContentTy‌pe(MediaType.parseMed‌iaType("application/p‌df")); and this worked for me — M.T, Aug 16 '16 at 06:10

Taking the comments from the main question into a formal answer. Important is that the browser is sending Accepts: */* or at least application/pdf or it will give an error on the request.

@RequestMapping(method = RequestMethod.GET, value = "/explorer/file/{id:.+}", produces = "application/pdf")
@ResponseBody
public ResponseEntity<?> getFile(@PathVariable Integer id) {
    String filename = explorerService.getById(id).getPath();
    try {
        return ResponseEntity.ok(resourceLoader.getResource("file:" + filename));
    } catch (Exception e) {
        return ResponseEntity.notFound().build();
    }
}

HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.parseMediaType("application/pdf")); return new ResponseEntity<>(resourceLoader.getResource("file:" + filename), headers, HttpStatus.OK); you were right thanks — M.T, Aug 16 '16 at 06:03
