Spring Boot POST PDF内容类型'application / pdf不支持

Question

I'm trying to have a backend where I send two PDF's and work with those. For that I have to implement a REST service but I'm not able to receive them.

PostMapping

@PostMapping("/post")
    CompareJob compareJob(@RequestBody File file1) {
        System.out.print("Received File: " + file1);
        CompareJob compareJob = new CompareJob();
        return compareJob;
    }

To do the POST requests I use Postman where I've set following things:

Headers -> Content-Type: application/pdf

Body -> Binary: testPDF.pdf

This is the response I'm getting:

{
    "timestamp": "2019-03-12T13:55:12.898+0000",
    "status": 415,
    "error": "Unsupported Media Type",
    "message": "Content type 'application/pdf;charset=UTF-8' not supported",
    "path": "/post"
}

I'm very new to REST services and would greatly appreciate some hints what is wrong.

Thanks for any help!

Edit after amin10043 suggestion:

@PostMapping("/post")
    CompareJob compareJob(@RequestParam("file1") MultipartFile file1) {
        System.out.print("Received File: " + file1);
        CompareJob compareJob = new CompareJob();
        return compareJob;
    }

After reading I should not check Content-Type in Postman I'm getting this response:

{
    "timestamp": "2019-03-12T14:37:52.765+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "Current request is not a multipart request",
    "path": "/post"
}

My fault was that I uploaded the pdf as a binary and not as form-data in postman. Must be set like this: https://snag.gy/H4w5S8.jpg

如果要上传文件，最好使用Multipartfile ，也请将输入参数从@RequesBody为@RequestParam("your parameter name") ，这样邮递员就可以向请求中添加正确的标头并且应该可以使用。
