来自使用Apache CXF的Web服务的响应显示“无绑定操作信息…”

Question

问题描述可能很长。请耐心等待，并提供任何形式的帮助，因为我是新的网络服务。

我所做的：我使用ApacheCXFRI在java中创建了一个web服务。我只是创建了一个类，并使用自下而上的开发方法来生成SEI、WSDL和XML文件。

问题是：现在，如果我请求http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort/whatIsTheAnswer，它会产生输出为No绑定操作信息，同时调用参数未知的未知方法。答复如下：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <soap:Fault>
      <faultcode>soap:Server</faultcode>
      <faultstring>No binding operation info while invoking unknown
      method with params unknown.</faultstring>
    </soap:Fault>
  </soap:Body>
</soap:Envelope>

生成的WSDL为：

<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:tns="http://ws.service.com/"

      <wsdl:input name="whatIsTheAnswer">

      <soap:address location="http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort" />
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

deepthink课程包括：

@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了一些错误：

Answer 1

有人用GET请求调用您的SOAP-WebService，但SOAP-WebServices无法接收GET请求。你应该告诉他/她不要像这里描述的那样用GET请求调用我的SOAP web服务，或者用GET请求调用我的web服务。

Answer 2

我也有同样的问题。使用cxf 2.6 2.7，chrome或firefox等网络浏览器的这一请求根本不起作用。我试着在cxf中使用一个客户机，效果很好！您的web服务正在工作，但您无法通过web浏览器执行请求，您需要一个客户机，因为客户机知道XML的要求。

Answer 3

通常，如果传入的soap方法与WSDL不正确匹配，就会发生这种异常。在这种情况下，soap消息无法映射到服务上的适当方法。CXF就是不知道该怎么办。仔细检查传入的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);
    }
}

我要做的是在@WebService中添加WSDL位置和endpoint接口。此外，您使用的是Java优先的方法，因此您的方法应该使用@WebMethod（action=“whatIsTheAnswer”）进行注释。因此，如果该方法没有注释CXF“理解”您的web服务根本不包含任何方法，并在调用参数未知的未知方法时说：无绑定操作信息
