title: Spring - display PDF-file in browser instead of downloading
body: <p>i am trying to display a pdf in my browser with spring.
  my problem is that the browser downloads the file instead of displaying it.
  this is my code:</p>
  
  <pre><code>@RequestMapping(value="/getpdf1", method=RequestMethod.GET)
  public ResponseEntity&lt;byte[]&gt; getPDF1() {
  
  
      HttpHeaders headers = new HttpHeaders();
  
      headers.setContentType(MediaType.parseMediaType("application/pdf"));
      String filename = "pdf1.pdf";
  
      headers.add("content-disposition", "inline;filename=" + filename);
  
      headers.setContentDispositionFormData(filename, filename);
      headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
      ResponseEntity&lt;byte[]&gt; response = new ResponseEntity&lt;byte[]&gt;(pdf1Bytes, headers, HttpStatus.OK);
      return response;
  }
  </code></pre>
  
  <p>i am looking forward to your answers!
  thanks</p>
