没有端点的适配器;您的终端节点是否使用@Endpoint进行批注，或者它是否实现了受支持的接口，如 MessageHandler 或 PayloadEndpoint？

我正在为带有JMS示例的Spring-WS而苦苦挣扎。我根据Spring建议设置Spring-WS和JMS布线。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] -

我的终点代码是

    Image request = requestElement.getValue();
    return imageRepository.storeImage(request.getName());
}

我的客户请求是

有人可以帮忙吗？

答案 1

我收到了类似的错误消息。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。这导致操作描述（在 WSDL 中）和已实现方法的描述（在端点中）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文件并按以下步骤操作，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);
  }
