来自使用Apache CXF的Web服务的响应显示“无绑定操作信息...”

Question

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <soap:Fault>

生成的WSDL是：

DeepThink类包括：

@WebService(targetNamespace = "http://ws.service.com/", portName = "DeepThoughtPort", serviceName = "DeepThoughtService")
public class DeepThought {
    public String whatIsTheAnswer(@WebParam(name = "arg0") String interviewer) {
        return ("The answer " + interviewer);
    }
}

请求时的控制台输出也显示一些错误：

Answer 1

通常，如果传入的soap方法与WSDL不正确匹配，则通常会发生此异常。在这种情况下，soap消息无法映射到服务上的适当方法。CXF只是不知道该怎么办。再次检查传入的soap消息。

上述解释的来源。

可能的解决方案：

@WebService(targetNamespace = "http://ws.service.com/",
        portName = "DeepThoughtPort",
        serviceName = "DeepThoughtService",
        endpointInterface = "your.pck.DeepThoughtService",
        wsdlLocation = "WEB-INF/wsdl/DeepThoughtService.wsdl")
public class DeepThought {

    @WebMethod(action = "whatIsTheAnswer")
    public String whatIsTheAnswer(@WebParam(name = "arg0") String interviewer) {
        return ("The answer " + interviewer);
    }
}
