Spring - 在浏览器中显示PDF文件而不是下载

问题描述

我想用spring在浏览器中显示pdf。
我的问题是浏览器下载文件而不是显示它。
这是我的代码：

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;
}

我期待你的回答！
谢谢

推荐答案

你差不多完成了。只需删除

You are almost done. Just remove

headers.setContentDispositionFormData(filename, filename);

。将multipart / form-data发布到服务器时应该使用它。

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