1. Phenomenon

Integrating the web service of Spring + CXF, the WSDL is successfully published, but an error is reported when calling
org.apache.cxf.common.i18n.uncheckedexception: no operation was found with

2. Solution 1

: add targetNamespace in the service interface

package com.gblfy.service;

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

@WebService(targetNamespace = "http://impl.service.gblfy.com/")
public interface IUserService {

    @WebMethod
    public String getCxf(@WebParam(name = "reqXml") String reqXml);
}

Implementation class

package com.gblfy.service.impl;

import com.gblfy.service.IUserService;

import javax.jws.WebService;

@WebService
public class UserServiceImpl implements IUserService {

    @Override
    public String getCxf(String reqXml) {

        System.out.println("Message received:" + reqXml);
        return "OK";
    }
}

client

     *
     * @param cxfUrl url address
     * @param method call method name
     * @param reqXml send message body
     * @return res return result
     * @throws Exception If there is an exception, output the exception on the console and throw the exception
     */
    public static String cxfClientParam(String cxfUrl, String method, Object... reqXml) throws Exception {
        String res = null;
        // Create a dynamic client
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient(cxfUrl);

        // If you need a password, you need to add a user name and password
        // client.getOutInterceptors().add(new ClientLoginInterceptor(USER_NAME, PASS_WORD));
        Object[] objects = new Object[0];
        try {
            // Basic format: invoke("method name", parameter 1, parameter 2, parameter 3....);
            objects = client.invoke(method, reqXml);
            res = objects[0].toString();
            System.out.println("Return data:" + res);
        } catch (java.lang.Exception e) {
            e.printStackTrace();
            throw e;
        }
        return res;
    }

3. Solution 2

Use QName and add the address of the service interface

package com.gblfy.service.client;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.springframework.stereotype.Component;

import javax.xml.namespace.QName;

/**
 * cxf client call (packaged inside the enterprise)
  *
  * @author gblfy
  * @date 2021-09-17
  */
@Component
public class CxfClient {
     public static void main(String[] args) throws Exception {
         String cxfUrl = "http://127.0.0.1:8080/spring_cxf_war/webservice/userWS?wsdl";
         String method = "getCxf";
         String reqXml = "cxf request message";

         //Call the service
         CxfClient.cxfClientParam(cxfUrl, method, reqXml);
     }

     /**
      * Single/multi-parameter calling tool class (Object type)
      *
      * @param cxfUrl url address
      * @param method call method name
      * @param reqXml send message body
      * @return res return result
      * @throws Exception If there is an exception, output the exception on the console and throw the exception
     */
    public static String cxfClientParam(String cxfUrl, String method, String reqXml) throws Exception {
        String res = null;
        // Create a dynamic client
         JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
         Client client = dcf.createClient(cxfUrl);

         // If you need a password, you need to add a user name and password
         // client.getOutInterceptors().add(new ClientLoginInterceptor(USER_NAME, PASS_WORD));
         Object[] objects = new Object[0];
         try {
             // Basic format: invoke("method name", parameter 1, parameter 2, parameter 3....);
             QName qName = new QName("http://impl.service.gblfy.com/",method);
             objects = client.invoke(qName, reqXml);
             res = objects[0].toString();
             System.out.println("Return data:" + res);
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
        return res;
    }
}
