如何在Dropwizard项目中使用Postman上传图像？

@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
public class ImageUploadResource {

    @POST
    public Response uploadImage(@FormDataParam("image") InputStream fileInputStream,
                                @FormDataParam("image") FormDataContentDisposition fileMetaData) {
        try {
            // 保存图像文件到指定位置
            String fileName = fileMetaData.getFileName();
            String filePath = "/path/to/save/" + fileName;
            saveFile(fileInputStream, filePath);

            // 进一步处理图像文件，如生成缩略图等

            return Response.ok("Image uploaded successfully").build();
        } catch (IOException e) {
            return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity("Failed to upload image").build();
        }
    }

    private void saveFile(InputStream inputStream, String filePath) throws IOException {
        OutputStream outputStream = new FileOutputStream(new File(filePath));
        int read;
        byte[] bytes = new byte[1024];
        while ((read = inputStream.read(bytes)) != -1) {
            outputStream.write(bytes, 0, read);
        }
        outputStream.flush();
        outputStream.close();
    }
}
