如何将Android中的多张图片上传到Spring Server？

@RestController
@RequestMapping("/upload")
public class ImageUploadController {

    @PostMapping("/images")
    public ResponseEntity<String> uploadImages(@RequestParam("images") MultipartFile[] images) {
        // 处理接收到的图片数据
        for (MultipartFile image : images) {
            // 将图片保存到服务器的指定位置
            saveImage(image);
        }
        
        // 返回上传成功的响应
        return ResponseEntity.ok("Images uploaded successfully");
    }

    private void saveImage(MultipartFile image) {
        // 实现将图片保存到服务器的逻辑
        // 可以使用Java的文件操作API来保存图片
    }
}

private void uploadImages(List<File> imageFiles) {
    OkHttpClient client = new OkHttpClient();
    MediaType mediaType = MediaType.parse("image/jpeg");

    MultipartBody.Builder builder = new MultipartBody.Builder()
            .setType(MultipartBody.FORM);

    for (File imageFile : imageFiles) {
        RequestBody requestBody = RequestBody.create(mediaType, imageFile);
        builder.addFormDataPart("images", imageFile.getName(), requestBody);
    }

    Request request = new Request.Builder()
            .url("http://your-spring-server/upload/images")
            .post(builder.build())
            .build();

    try {
        Response response = client.newCall(request).execute();
        if (response.isSuccessful()) {
            // 处理上传成功的响应
        } else {
            // 处理上传失败的情况
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}
