[FIXED] Springboot Required request part 'file' is not present

Issue

I am working on a file upload controller and I am currently getting the following error when testing in Postman.

{
    "timestamp": "2019-04-18T14:53:07.988+0000",
    "status": 400,
    "error": "Bad Request",
    "message": "Required request part 'file' is not present",
    "path": "/upload"
}

At the moment my controller is very simple but first I need to overcome this problem.

I have looked at the answers given [here](upload file springboot Required request part 'file' is not present"upload file springboot Required request part file is not present")!

But unfortunately, anything suggested here did not resolve my problem

Any help with this error would be appreciated

This is my controller:

@Controller
public class UploadController {

@ResponseBody
@RequestMapping(value = "/upload", method = RequestMethod.POST)
public boolean upload(@RequestParam("file") MultipartFile file) throws IOException {

        try {
            if (!file.isEmpty()) {
                return true;
            } else {
                return false;
            }
        }
        catch(Exception e){
            e.printStackTrace();
            return false;
        }

    }
}

Solution

In postman under "key" I wasn't setting anything. I needed to set this as 'file'. I previously made the assumption all I had to do was click the drop-down and select file.

I will include below all the updated code & a link to the image which explains this better(I couldn't display image here as reputation < 10)

@RestController
public class UploadController {

    @PostMapping("/upload")
    @ResponseBody
    public boolean upload(@RequestParam("file") MultipartFile file) {
        try{
            if(file.isEmpty() ==false){
                System.out.println("Successfully Uploaded: "+ file.getOriginalFilename());

                return true;
            }
            else{
                System.out.println("ERROR");
                return false;
            }
        }
        catch(Exception e){
            System.out.println(e);
            return false;
        }
    }
}
