我有一个java控制器，它必须向我发送一些文本数据和不同的字节数组。因此，我正在构建一个多部分请求，并将其从HttpServletResponse写入流。

现在我的问题是如何在客户端解析响应并提取多个部分。

服务器代码片段：-

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        // Prepare payload
        builder.addBinaryBody("document1", file);
        builder.addBinaryBody("document2", file2);
        builder.addPart("stringData", new StringBody(jsonData, ContentType.TEXT_PLAIN));

        // Set to request body

        HttpEntity entity = builder.build();
        postRequest.setEntity(entity);

客户端代码段：-

        HttpPost httpPost = new HttpPost(finalUrl);

        StringEntity entity = new StringEntity(json);
        httpPost.setEntity(entity);
        httpPost.setHeader("Content-type", APPLICATION_JSON_TYPE);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        CloseableHttpResponse response = httpClient.execute(httpPost);
        InputStream in = new BufferedInputStream(response.getEntity().getContent());

我检查了CloseableHttpResponse和HttpEntity，但它们都没有提供解析多部分请求的方法。

编辑1：这是我在客户端流中收到的示例响应：-
