问题描述可能很长。由于我是 Web 服务的新手，请耐心等待并提供任何帮助。

我所做的： 我使用 Apache CXF RI 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。

问题是什么： 现在，如果我请求“ ”，它会在调用参数未知的未知方法时http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort/whatIsTheAnswer产生输出为无绑定操作信息。 响应如下：

<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WSDL的是：

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

      <wsdl:output message="tns:whatIsTheAnswerResponse"
      name="whatIsTheAnswerResponse"></wsdl:output>
    </wsdl:operation>
  </wsdl:portType>

    <wsdl:operation name="whatIsTheAnswer">
      <soap:operation soapAction="" style="document" />
      <wsdl:input name="whatIsTheAnswer">
        <soap:body use="literal" />
      </wsdl:input>
      <wsdl:output name="whatIsTheAnswerResponse">

    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="DeepThoughtService">
    <wsdl:port binding="tns:DeepThoughtServiceSoapBinding"
    name="DeepThoughtPort">
      <soap:address location="http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort" />
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

该DeepThought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：

通常，如果传入的 soap 方法与 WSDL 不正确匹配，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 只是不知道该怎么做。仔细检查传入的肥皂消息。

以上解释的来源。

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);
    }
}

我要做的是将 WSDL 位置和 endpointInterface 添加到您的@WebService. 此外，您正在使用 Java-First 方法，因此您的方法应使用@WebMethod(action = "whatIsTheAnswer"). 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说：No binding operation info while invoking unknown method with params unknown.

我有同样的问题。使用 cxf 2.6 2.7 像 chrome 或 firefox 这样的网络浏览器发出的这个请求没有奏效。我尝试使用 cxf 中的客户端，它可以工作！您的 Web 服务正在运行，但您无法通过 Web 浏览器发出请求，您需要一个客户端，因为客户端知道 XML 的要求。

您应该在 url 末尾使用 wsdl（例如添加 ?wsdl）进行查询，以检查您的 Web 服务实现是否有效。浏览器不能作为soap 客户端发送任何soap 请求。

有人打电话给您SOAP WebService请求GET，但SOAP WebServices无法收到GET请求。你应该对他/她说不要打电话给我SOAP WebService的请求，或者用这里描述的请求GET打电话给我的网络服务。GET

是的，已经回答您不能直接在浏览器 url 中访问该服务。您需要这样的客户端代码

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.junit.Test;


@Test
public void testWhatIsTheAnswer() {

    JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();

    factoryBean.getInInterceptors().add(new LoggingInInterceptor());
    factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
    factoryBean.setServiceClass(DeepThought.class);
    factoryBean.setAddress("http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort");

    DeepThought service = (DeepThought) factoryBean.create();

    service.whatIsTheAnswer("some answer");

}
