Question

我在Java中有一个SOAP Message对象attachments。现在我使用TransformerFactory将消息的SOAPPart转换为String并使用{{1}发送它post方法。到这里它工作正常。但是当我尝试通过转换为String并附加到String writer来发送SOAPMessage中的附件时，我得到了一个异常。

附件是我要作为附件发送的文件。

以下是我的代码片段

HttpAsyncClient

我得到的例外

        final SOAPMessage message;
        final StringWriter sw = new StringWriter();

        try {
            TransformerFactory.newInstance().newTransformer().transform(new DOMSource(message.getSOAPPart()),
                    new StreamResult(sw));
            sw.append("\n");
            TransformerFactory.newInstance().newTransformer().transform(new StreamSource(attachment), new StreamResult(sw));
        } catch (TransformerException e) {
            throw new RuntimeException(e);
        }

        HttpPost post = new HttpPost(url.toString());
        HttpEntity entity = new StringEntity(sw.toString(), HTTP.UTF_8);

        post.addHeader("Content-Type", "text/xml; charset=utf-8");
        post.setConfig(params);
        post.setEntity(entity);
        client.execute(post, new AsyncResponseHandler<>(subscribedUsers, campaignId, path, isOnline,
                CommunicationConstants.EMAIL));

我的请求字符串是我在第67行中遇到异常，其中另一个xml块正在启动，因为它们将它们作为单独的xml进行处理。
