You need to specify media type for BMP images.
According to RFC standart, the media type for bmp images is "image/bmp"
RFC standart:
https://www.rfc-editor.org/rfc/rfc7903.html
https://www.iana.org/assignments/media-types/media-types.xhtml#image
MediaType class contain just a few string constants. You can extend it according to RFC. Also you can define any custom media type string in produces tag.
@GetMapping(
value = "/{id}",
produces = "image/bmp"
)
public @ResponseBody
byte[] getImage(@PathVariable("id") String id) throws IOException {
}
