My POJO class

@JsonPropertyOrder({ "file", "data" })
public class FileWithObject<T> {

    @JsonProperty("file")
    private MultipartFile file;
    @JsonRawValue
    @JsonProperty("data")
    private T data;
}

MY REST CONTOLLER

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

Answer 1

I have done this by use of Meta-Data concept there are few changes I did in controller and bean

Controller

@RequestMapping(value="/filestore/{bucket-uuid}/appsport.com/listOfObjectsWithSingleFile/{folder}",
        method = RequestMethod.POST)
@ResponseBody
public String listOfObjectsWithSingleFile(
        @PathVariable(name="bucket-uuid") String bucketUUId, @PathVariable(name="folder") String folder,
        FileWithObject objects) { // change this Set<FileWithObject> rawData to FileWithObject objects
    return pingResponse;
}

Bean

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

    @JsonProperty("file")
    private MultipartFile file;
    @JsonProperty("files")
    private List<MultipartFile> files;
    @JsonRawValue
    @JsonProperty("data")
    private T data;

    // work like (meta-data)
    List<FileWithObject> rawData;
    // getter setter
}

Image's For Request

@ResponseBody

    @PathVariable(name="folder", required = false) String folder,Set<FileWithObject> rawData) {
