使用Apache CXF的Web服务的响应显示“无绑定操作信息..” [英] Response from Web service using Apache CXF shows "No binding operation info.."
问题描述
问题描述可能很长。请耐心等待,因为我是新的网络服务。
The problem description might be long. Please be patient and provide any kind of help since I am new to the web services.
我做了什么:
I已经使用Apache CXF RI在java中创建了一个Web服务。我简单地创建了一个类,并使用自下而上的开发方法来生成SEI,WSDL和XML文件。
What I have done: I have created a web service in java using Apache CXF RI. I simply created a class and used bottom up development approach to generate SEI, WSDL and XML files.
问题是:
现在,如果我请求 http:// localhost:8084 / DeepThoughtWS / services / DeepThoughtPort / whatIsTheAnswer
,它将生成输出为 不绑定操作调用未知方法的信息,参数未知。
响应如下:
What the problem is:
Now, If I request "http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort/whatIsTheAnswer
", it produces output as No binding operation info while invoking unknown method with params unknown.
The response is as follows:
<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
是:

DeepThought
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显示一些错误也是:
The console output at the time of request shows some errors too:

推荐答案
如果传入的soap方法
与WSDL不正确匹配,则通常会发生异常。在这种情况下,肥皂消息
无法映射到服务上的适当方法。 CXF只是
不知道该怎么办双重检查传入的肥皂消息。
In general, this exception usually occurs if the incoming soap method doesn't correctly match the WSDL. In such a case, the soap message could not be mapped to an appropriate method on the service. CXF just doesn't know what to do. Double check the incoming soap message.
可能的解决方案: / p>
Possible solution:
@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);
}
}
我要做的是添加WSDL位置和您的 @WebService
中的endpointInterface。另外你使用Java-First方法,所以你的方法应该用 @WebMethod(action =whatIsTheAnswer)
注释。所以如果方法没有注释 CXF
了解你的Web服务根本不包含任何方法,并说:调用时没有绑定操作信息未知的方法与params未知。
What I would do is to add the WSDL location and endpointInterface in your @WebService
. Also you are using Java-First approach so your method should be annotated with @WebMethod(action = "whatIsTheAnswer")
. So if the method is not annotated CXF
"understands" that your web service does not contain any methods at all and says: No binding operation info while invoking unknown method with params unknown.
