Spring - display PDF-file in browser instead of downloading

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:

@RequestMapping(value="/getpdf1", method=RequestMethod.GET)
public ResponseEntity<byte[]> 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<byte[]> response = new ResponseEntity<byte[]>(pdf1Bytes, headers, HttpStatus.OK);
    return response;
}

i am looking forward to your answers! thanks

View in browser (use inline) :

header.add(HttpHeaders.CONTENT_DISPOSITION, "inline; filename=" + pdfFile.getName());

For Download (use attachment) :

header.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=" + pdfFile.getName());

it's working you should try do that, get by filename and opnend in browers

  @GetMapping(value = "/pdf/{filename:.+}") public ResponseEntity<InputStreamResource> getTermsConditions(@PathVariable String filename) {

    File file = storageService.load(filename).getFile();
 
    HttpHeaders headers = new HttpHeaders();      
    headers.add("content-disposition", "inline;filename=" +fileName);
    
    InputStreamResource resource = new InputStreamResource(new FileInputStream(file));

    return ResponseEntity.ok()
            .headers(headers)
            .contentLength(file.length())
            .contentType(MediaType.parseMediaType("application/pdf"))
            .body(resource);
}

Content-Disposition to control either download or view in browser

View in browser

headers.add("Content-Disposition", "inline; filename=" + "example.pdf");

Download

headers.add("Content-Disposition", "attachment; filename=" + "example.pdf");

You are almost done. Just remove 

headers.setContentDispositionFormData(filename, filename);

from your code block. It should be used when posting multipart/form-data to the server.
