Spring-WS webservice with MTOM attachment - Hello world test
提问by ziggy
I am trying to create a simple Spring webservice which when called returns a file attachment as part of the SOAP response. The Enpoint class is shown below:
我正在尝试创建一个简单的 Spring webservice，它在被调用时返回一个文件附件作为 SOAP 响应的一部分。Enpoint 类如下所示：
And finally the endpoint
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);
}
I would like the response to include the file as an attachement similar to the following response:
我希望响应包含文件作为类似于以下响应的附件：
Content-Type: multipart/related; boundary=MIMEBoundary4A7AE55984E7438034;
type="application/xop+xml"; start="<[email protected]>";
start-info="text/xml; charset=utf-8"
--MIMEBoundary4A7AE55984E7438034
content-type: application/xop+xml; charset=utf-8; type="application/soap+xml;"
content-transfer-encoding: binary

<soapenv:Envelope xmlns:soapenv="...."....>

content-type: application/octet-stream

Binary Data.....
--MIMEBoundary4A7AE55984E7438034--
I have tried to follow the documentation and the sample code in the spring-ws samples and for some reason the output i am getting is always this (i.e. the base64 data is not an attachement.
我试图遵循 spring-ws 示例中的文档和示例代码，出于某种原因，我得到的输出始终是这个（即 base64 数据不是附件。

As you can see, the payload is not an attachment. Here is how i have configured my application:

The file does get converted to base64binary. The JAXB clases are generated correctly. The Endpoint works but it is not including the file as an attachement. It is including it as part of the XML tag even though i have set mtomEnabled=true.
该文件确实被转换为 base64binary。JAXB 类正确生成。端点工作，但它不包括文件作为附件。即使我已经设置了 mtomEnabled=true，它也将它作为 XML 标记的一部分包含在内。
What am i missing?
我错过了什么？

Finally managed to get it to work. The configuration is more or less the same as what i had in my original post. I had to update the configuration file. Here is how my configuration file looks like now.
终于设法让它工作。配置或多或少与我在原始帖子中的配置相同。我不得不更新配置文件。这是我的配置文件现在的样子。

The changes i added were based on what i read on this article - blog.hpxn.net/2012/06/

Here is an example (based on the spring samples) that returns the attachment in MTOM format. I just tried it and the response is shown below:

To get the response returned as a SAAJ attachment rather than an MTOM attachment, i have to manually configure the SAAj factories as described in this thread How do I add an attachment to a response payload in Spring-WS?
要获得作为 SAAJ 附件而不是 MTOM 附件返回的响应，我必须手动配置 SAAj 工厂，如本线程如何将附件添加到 Spring-WS 中的响应有效负载中所述？
