我正在尝试创建一个简单的Spring Web服务,在调用时返回文件附件作为SOAP响应的一部分.Enpoint类如下所示:

最后是终点

@PayloadRoot(namespace="http://ws.mypackage.com", localPart="downloadMessageRequest")
    @ResponsePayload
    public JAXBElement<DownloadResponseType> invoke(@RequestPayload DownloadMessageRequest req) throws Exception  {

        DownloadResponseType response = new DownloadResponseType();
        DownloadResponseType.PayLoad payload = new DownloadResponseType.PayLoad();          

        javax.activation.DataHandler dataHandler = new javax.activation.DataHandler(new FileDataSource("c:\\temp\\maven-feather.png"));
        payload.setMessagePayLoad(dataHandler);
        response.setPayLoad(payload);

        return objectFactory.createDownloadMessageResponse(response);

    }

我希望响应将文件包含为类似于以下响应的附件:

Content-Type: multipart/related; boundary=MIMEBoundary4A7AE55984E7438034;
                         type="application/xop+xml"; start="<0.09BC7F4BE2E4D3EF1B@apache.org>";
                         start-info="text/xml; charset=utf-8"

我试图遵循spring-ws示例中的文档和示例代码,由于某种原因,我得到的输出总是这样(即base64数据不是附件.
