Answer 1

I solve this issue in this way.

My API Method

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/singleFileUploadWithObject/{folder}",
        method = RequestMethod.POST)
@ResponseBody
public String singleFileUploadWithObject(
        @PathVariable(name="bucket-uuid", required = true) String bucketUUId,
        @PathVariable(name="folder", required = false) String folder,
        FileWithObject rawData) {
    return pingResponse;
}

My FileWithObject DTO

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({ "file", "files", "data" })
public class FileWithObject<T> {

    @JsonProperty("file")
    private MultipartFile file;
    @JsonProperty("files")
    private MultipartFile[] files;
    @JsonRawValue
    @JsonProperty("data")
    private T data;
    // getter/setter and other...
}

Note:- For data parameter you can use the mapping process in the singleFileUploadWithObject method hope it's help you and other
