没有端点适配器; 您的端点是使用@Endpoint注释的,还是实现了MessageHandler或PayloadEndpoint等受支持的接口？

Question

我正在努力使用带有JMS示例的Spring-WS.我按照Spring的建议设置了Spring-WS和JMS接线.但我一直得到以下错误.我不知道如何绕过这个问题,任何帮助将不胜感激:

[org.springframework.ws.soap.server.endpoint.SoapFaultAnnotationExceptionResolver] -

[org.springframework.ws.samples.mtom.ws.ImageRepositoryEndpoint@1c8b0b1]: 
Is your endpoint annotated with @Endpoint, or does it implement a supported interface like MessageHandler or PayloadEndpoint?

我的Web服务接线是

<bean id="imageRepository"
    class="org.springframework.ws.samples.mtom.service.StubImageRepository" />

<!-- JMS WIRING TO WS START -->
<bean id="messageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory" />

<bean id="messageDispatcher"
    class="org.springframework.ws.soap.server.SoapMessageDispatcher">

            <property name="messageReceiver" ref="messageDispatcher" />
        </bean>
    </property>
</bean>

我的终点代码是

@PayloadRoot(localPart = "StoreImageRequest", namespace = "http://www.springframework.org/spring-ws/samples/mtom")
@ResponsePayload
public String  store(@RequestPayload JAXBElement<Image> requestElement) throws IOException {
    Image request = requestElement.getValue();
    return imageRepository.storeImage(request.getName());
}

我的架构是

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.springframework.org/spring-ws/samples/mtom"
    xmlns:tns="http://www.springframework.org/spring-ws/samples/mtom"
    xmlns:xmime="http://www.w3.org/2005/05/xmlmime" elementFormDefault="qualified">
    <element name="StoreImageRequest" type="tns:Image"/>
    <element name="LoadImageRequest" type="string"/>
    <element name="LoadImageResponse" type="tns:Image"/>
    <complexType name="Image">
        <sequence>
            <element name="name" type="string"/>
        </sequence>
    </complexType>
</schema>

我的客户请求是

<ns2:StoreImageRequest xmlns:ns2="http://www.springframework.org/spring-ws/samples/mtom"><ns2:name>spring-ws-logo.png</ns2:name></ns2:StoreImageRequest>

有人可以帮忙吗？

我有一个类似的错误消息.我的问题出在我从XSD生成的请求和响应类中.它错过了@XMLRootElement注释.这导致操作的描述(在WSDL中)和实现的方法的描述(在Endpoint中)不匹配.将JAXBElement添加到我的端点方法解决了我的问题.

import javax.xml.bind.JAXBElement;

@PayloadRoot(namespace = "http://foo.bar/books", localPart = "GetBook")
@ResponsePayload
public JAXBElement<MyReponse> getBook(@RequestPayload JAXBElement<MyRequest> myRequest) {
    ...

我正在使用 WSDL 文件并按如下方式操作，然后它起作用了。

  @PayloadRoot(namespace = "http://www.myservice/v1.0/query", localPart = "queryRequest")
  @ResponsePayload
  public JAXBElement<QueryResponse> queryAddrLocation(@RequestPayload JAXBElement<QueryRequest> queryRequest) {
    System.out.println("Welcome to " + queryRequest);
    return createJaxbElement(new QueryResponse(), QueryResponse.class);
  }

  private <T> JAXBElement<T> createJaxbElement(T object, Class<T> clazz) {
    return new JAXBElement<>(new QName(clazz.getSimpleName()), clazz, object);
  }

我不确定你的完整端点看起来如何，但该类应该用注释@Endpoint或者它应该实现MessageHandler或PayloadEndpoint。

您可以使用的另一件事是方法签名。Spring-WS 的端点映射非常智能：它尝试将方法签名中的输入和输出类映射到 WSDL 文件。您确定 @ResponsePayLoad 是 String，而不是 吗StoreImageResponse？

例如，这是我的端点之一的方法签名

@PayloadRoot(
    localPart = "GetHiredCandidatesRequest", 
    namespace = DEFAULT_NAMESPACE
)
@ResponsePayload
public GetHiredCandidatesResponse getCandidates (
    @RequestPayload GetHiredCandidatesRequest getCandidate,
    MessageContext messageContext) {
    ...
}

在我的 WSDL 中定义如下：

<wsdl:operation name="GetHiredCandidates">
    <wsdl:input message="tns:GetHiredCandidatesRequest" name="GetHiredCandidatesRequest"></wsdl:input>
    <wsdl:output message="tns:GetHiredCandidatesResponse" name="GetHiredCandidatesResponse"></wsdl:output>
</wsdl:operation>

你看到它是如何映射的吗？也许您的签名中缺少类似的内容。
