我用的是spring soap ws.

我有以下 JAXB 域类对应于复杂类型

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "reference",
    "reason"
})
@XmlRootElement(name = "request-message")
public class RequestMessageType {

    @XmlElement(name = "reference", required = true)
    protected String reference;
    @XmlElement(name = "reason")
    protected String reason;

   // I have getters and setters but removed here.
}

我有以下带有@XmlRegistry 注释的类

@XmlRegistry
public class ObjectFactory {

    private final static QName _RequestMessage_QNAME = new QName("http://namespace/url", "request-message");

    public ObjectFactory() {
    }

    @XmlElementDecl(namespace = "http://namespace/url", name = "request-message")
    public JAXBElement<RequestMessageType> createDisconnectRequestMessage(RequestMessageType  value) {
        return new JAXBElement<RequestMessageType>(_RequestMessage_QNAME, RequestMessageType.class, null, value);
    }    
}

以下是端点

   @Endpoint
    public class FirstEndPoint {

        private static final String NAMESPACE_URI = "http://first/url/version";

        private static final Logger LOG = Logger.getLogger(FirstEndPoint.class);

        @PayloadRoot(namespace = NAMESPACE_URI, localPart = "request-message")
        @ResponsePayload
        public JAXBElement<ResponseMessageType> requestMessage(@RequestPayload JAXBElement<RequestMessageType> requestMessage) {
            LOG.info("request-message : first version ID : " + requestMessage.getValue().getReference());
        //Preparing response and return response 
        }
    }

    @Endpoint
    public class SecondEndPoint {

        private static final String NAMESPACE_URI = "http://second/url/version";
        private static final Logger LOG = Logger.getLogger(SecondEndPoint.class);


        @PayloadRoot(namespace = NAMESPACE_URI, localPart = "request-message")
        @ResponsePayload
        public JAXBElement<ResponseMessageType> requestMessage(@RequestPayload JAXBElement<RequestMessageType> requestMessage) {
            LOG.info("request-message : second version ID : " + requestMessage.getValue().getReference());
         //Preparing response and return response 

        }
    }

当我发出 Soap 请求时，我使用的是在 soap 请求的端点中给出的 NAMESPACE_URI。

在这里，在这种情况下，我得到以下响应

<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">unexpected element (uri:"http://first/url/version", local:"request-message"). Expected elements are &lt;{http://namespace/url}request-message&gt;</faultstring>
        </SOAP-ENV:Fault>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

如果我在端点和 soap 请求中使用“http://namespace/url”作为 NAMESPACE_URI，我得到了正确的响应，但我尝试使它对于具有两个不同命名空间的两个端点有所不同，那么它不起作用并给出上述响应。

如何为具有相同 JAXB 类的两个不同端点使用两个不同的命名空间？我对 spring 和网络服务完全陌生。

附加信息:RequestMessageType 类和 ObjectFactory 类在一个包中，在 package-info.java 命名空间中是

@javax.xml.bind.annotation.XmlSchema(namespace="http://namespace/url",elementFormDefault=javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.example

我需要更改 package-info.java 文件中的任何内容吗？

我创建了一个示例项目。我希望它能对你有用。您可以在这里查看:https://github.com/angeloimm/spring-ws-sample 基本上这是我的 WSDL 文件(在 SOAP Web 服务中，所有文件都由 WSDL 控制):

如您所见，我定义了 2 个复杂类型:abstractRequest 和 abstractResponse。然后我实现它们通过使用元素 requestImplementation,requestImplementation2,responseImplementation,responseImplementation2根据 WS-I 规范，您需要使用单独的操作和元素

然后我写了这个端点:

@Endpoint
public class SampleEndpoint
{
    private static final Logger logger = LoggerFactory.getLogger(SampleEndpoint.class.getName());
    private static final String NAME_SPACE_URI = "http://www.example.org/SpringSample/";

    @PayloadRoot(namespace = NAME_SPACE_URI, localPart="requestImplementation")
    @ResponsePayload
    public JAXBElement<AbstractResponse> operationOneResp(@RequestPayload JAXBElement<AbstractRequest> ar)
    {
        if( logger.isDebugEnabled() )
        {
            logger.debug("Operation 1 request "+ar.getValue().getReqName());
        }
        ObjectFactory of = new ObjectFactory();
        AbstractResponse aResp = of.createAbstractResponse();
        aResp.setResponseName("operation 1 response");
        JAXBElement<AbstractResponse> result = of.createResponseImplementation(aResp);
        return result;
    }
    @PayloadRoot(namespace = NAME_SPACE_URI, localPart="requestImplementation2")
    @ResponsePayload
    public JAXBElement<AbstractResponse> operationTwoResp(@RequestPayload JAXBElement<AbstractRequest> ar)
    {
        if( logger.isDebugEnabled() )
        {
            logger.debug("Operation 2 request "+ar.getValue().getReqName());
        }
        ObjectFactory of = new ObjectFactory();
        AbstractResponse aResp = of.createAbstractResponse();
        aResp.setResponseName("operation 2 response");
        JAXBElement<AbstractResponse> result = of.createResponseImplementation(aResp);
        return result;
    }
}

正如您现在看到的，我总是在这两种方法中使用 AbstractRequest 和 AbstractResponse JAXBElement。这 2 个方法也可以在 2 个不同的端点

希望这就是你所需要的并且对你有用
