Spring WS web服务。使用SAAJ向响应添加附件-endpoint无适配器

Question

为此，我实现了一个endpoint，它只是将来自本地文件系统的映像附加到响应。

@Endpoint
public class TestEndPoint {

private SaajSoapMessageFactory saajMessageFactory;

@PayloadRoot(namespace="http://ws.mypackage.com", localPart="downloadMessageRequestSaaj")
    @ResponsePayload
    public JAXBElement<DownloadResponseSaajType> invoke(@RequestPayload DownloadMessageRequestSaaj req, MessageContext context ) throws Exception  {

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

        DataHandler handler = new javax.activation.DataHandler(new FileDataSource("c:\\temp\\maven-feather.png"));

            SaajSoapMessage message = saajMessageFactory.createWebServiceMessage();
            message.addAttachment("picture", handler);

            context.setResponse(message);

            payload.setMessagePayLoad(handler);

            return objectFactory.createDownloadMessageResponseSaaj(response);  

    }

    public void setSaajMessageFactory(SaajSoapMessageFactory saajMessageFactory){
        this.saajMessageFactory = saajMessageFactory;
    }

    public SaajSoapMessageFactory getSaajMessageFactory(){
        return saajMessageFactory;
    }
}

Saaj属性的深度注入如下所示：

<sws:annotation-driven/>

<bean id="soapMessageFactory" class="javax.xml.soap.MessageFactory" factory-method="newInstance" />
<bean id="saajMessageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
        <constructor-arg ref="soapMessageFactory" />
</bean>

<bean id="myService" class="com.mypackage.TestEndPoint">
    <property name="saajMessageFactory" ref="saajMessageFactory" />
</bean>

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Server</faultcode>
         <faultstring xml:lang="en">No adapter for endpoint [public javax.xml.bind.JAXBElement&lt;com.mypackage.ws.DownloadResponseSaajType> com.mypackage.TestEndPoint.invoke(com.mypackage.ws.DownloadMessageRequestSaaj,org.springframework.ws.context.MessageContext) throws java.lang.Exception]: Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?</faultstring>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

public JAXBElement<DownloadResponseSaajType> invoke(@RequestPayload DownloadMessageRequestSaaj req)

但是，问题是我需要访问MessageContext才能添加附件。可能是我的配置哪里错了？

我相信在任何一种情况下，您的客户将需要知道附件，所以我建议坚持使用mtom（因为它正在成为标准）

检查您使用的是哪个版本的spring-ws，以及您使用的是哪个maven group-id。我得到了同样的错误，因为这个特性是最近添加的（我想？）。
