具有整数数据类型的MultipartEntityBuilder addPart值

Question

我正在使用MultipartEntityBuilder类在服务器上上传多个图像。 与多个图像，我想发送job_id这是整数类型，但它不支持，它仅支持String和It给我编译时错误。

MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

    for (int i = 0; i < returnImageValue.size(); i++) {
        FileBody fileBodyImage = new FileBody(new File(returnImageValue.get(i)));
        multipartEntityBuilder.addPart("upload_image[]", fileBodyImage);
    }

  multipartEntityBuilder.addPart("job_id", 1);// In this line I want to use job_id as integer, but it did not work. It is getting me compile time error.

请建议我如何解决。
