WebService - [Debug] javax.xml.ws.WebServiceException: Undefined port type

背景：

使用JDK来开发java web service (Create a SOAP-based RPC style web service endpoint by using JAX-WS)。

具体请看 -> WebService - 使用JDK开发WebService

代码：

import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import java.net.MalformedURLException;
import java.net.URL;

public class WebServiceClient {
    public static void main(String[] args) throws MalformedURLException {

        URL url = new URL("http://127.0.0.1:8080/WS_Server/Webservice?wsdl");
        QName qname = new QName("http://webservice/", "WebServiceImplService");

        Service service = Service.create(url, qname);

        WebServiceI serviceI = service.getPort(WebServiceI.class);

        System.out.println(serviceI.sayHello("cuixunxu "));

    }

错误：

Exception in thread "main" javax.xml.ws.WebServiceException: Undefined port type: {http://webservice/}WebServiceI
    at com.sun.xml.internal.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:456)
    at com.sun.xml.internal.ws.client.WSServiceDelegate.getPort(WSServiceDelegate.java:463)
    at javax.xml.ws.Service.getPort(Service.java:188)
    at webservice.client.WebServiceClient.main(WebServiceClient.java:19)

解决方法：

@WebService的接口类WebServiceI代码：

package webservice;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface WebServiceI {

    @WebMethod
    String sayHello(String name);

    @WebMethod
    String save(String name,String pwd);

}

WebServiceI接口的实现类WebServiceImpl类的代码：...注意，需要在@WebService注解后面加上接口的全路径

package webservice;

import webservice.WebServiceI;

import javax.jws.WebService;

@WebService(endpointInterface="webservice.WebServiceI")
public class WebServiceImpl implements WebServiceI {
    @Override
    public String sayHello(String name) {
        return name + "is calling!!!";
    }

    @Override
    public String save(String name, String pwd) {
        return "Receive name: " + name + " and pwd: " + pwd;
    }
}
