Test interface

    @ApiOperation (value = "Single file upload test interface" ) 
    @PostMapping (value = "/ file" )
     public String fileUpload (MultipartFile file) {
         if (file.getSize ()> 0 ) { 
            System.out.println ( "Upload Success " ); 
        } 
        return " " ; 
    }

The swagger or postman test found that the file parameter cannot receive the file and is always null.
