CXF动态客户端总是提示No operation was found with the name {...},命名空间问题:
http://pangsir.iteye.com/blog/1492508
当我们使用CXF动态客户端调用WebService接口容易出现如下问题:
Exception in thread "main" org.apache.cxf.common.i18n.UncheckedException: No operation was found with the name {http://impl.service.jws/}sum.
	at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:289)
	at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:283)
	at cxf.bootstrap.CxfDynamicClientOnJwsRtWeb.main(CxfDynamicClientOnJwsRtWeb.java:36)

这个问题是由这个问题因为SIB和SEI类的targetNamespace统一导致的,解决方法
SIB的targetNamespace的命名空间为SEI对应的命名空间targetNamespace相同即可。
1.第一种方式为配置SIB和SEI的targetNamespace相同:
SIB:
package jws.service.impl;

import javax.jws.WebService;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import entity.User;
import jws.service.JwsIService;
/**
 * Service implementation Bean(SIB)
 * RPC接口实现
 * 注意这里的targetNamespace的命名空间为SEI对应的命名空间,注意最后要加/
 * 否则利用CXF动态客户端调用时,会找不到
 * Exception in thread "main" org.apache.cxf.common.i18n.UncheckedException: 
 * No operation was found with the name {http://impl.service.jws/}sum.

@WebService(endpointInterface="jws.service.JwsIService",
        serviceName = "jwsService", 
        portName = "jwsPort",
        targetNamespace = "http://service.jws/"
//        targetNamespace = "http://www.donald.service/jws_service/"
    )
public class JwsServiceImpl implements JwsIService {
private static final Logger log = LoggerFactory.getLogger(JwsServiceImpl.class);
	@Override
	public int sum(int firstNum, int secondNum) {
		int result = firstNum+secondNum;
		log.info("======"+firstNum+"+"+secondNum+"="+result);
		return result;
	}
}

SEI:
package jws.service;

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

import entity.User;
/**
 * service endpoint interface(SEI)
 * RPC接口
 * 如果返回结果时实例类,则targetNamespace必须用http://service.jws/,即http://+SEI倒序报名+/
 * 没有的话可以,targetNamespace可任意指定http://www.donald.service/jws_service/
 * @author donald

 */
@WebService(
		targetNamespace = "http://service.jws/"
//		targetNamespace = "http://www.donald.service/jws_service/"
		)
public interface JwsIService {
	//@WebMethod注解可写可不写
//	@WebMethod 
	@WebResult(name="sumResult")
	public int sum(@WebParam(name="firstNum")int firstNum,
			@WebParam(name="secondNum")int secondNum);
	
}

SIB和SEI的@WebService注解中的targetNamespace要相同,
SIB的@WebService的targetNamespace对应为SEI的targetNamespace。

动态客户端:
package cxf.bootstrap;


import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.apache.cxf.transport.http.HTTPConduit;
import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import jws.service.User;
import util.JsonUtil;

/**
 * CXF 动态代理模式,不用生成本地WS代理类,
 * 通过反射调用 WS 的对应的方法,传入相应的参数
 * 访问cxf-server-web项目下的webservice;
 * 测试jaxws-rt发布WebService web方式。
 * 此测试实例,用于测试SEI和SIB的targetNamespace指定的webService接口:
 * http://localhost:8080/cxf_server_web/jws_services?wsdl;
 * @author donald
 * 2017年7月8日
 * 下午7:24:12
 */
public class CxfDynamicClientOnJwsRtWeb {
	private static final Logger log = LoggerFactory.getLogger(CxfClient.class);
	private static final String JWS_RT_WSDL_URI = "http://localhost:8080/cxf_server_web/jws_services?wsdl";
	public static void main(String[] args) throws Exception {
		log.info("======CXF-WS Dynamic Client start!======");
		JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
		Client client =  dcf.createClient(JWS_RT_WSDL_URI);
		HTTPConduit conduit = (HTTPConduit)client.getConduit(); 
		HTTPClientPolicy policy = new HTTPClientPolicy(); 
		policy.setConnectionTimeout(10000); 
		policy.setAllowChunking(false); 
		policy.setReceiveTimeout(10000); 
		conduit.setClient(policy);	
		Object[] invokeResult = client.invoke("sum", 17,8);
		log.info("=======sumResult:" + invokeResult[0]);
	}
}

2.第二种方式动态客户端直接通过QName调用WebService对应的操作,
这种方式针对SIB和SEI的targetNamespace不相同,同时不再同一个包:

动态客户端:
package cxf.bootstrap;

import javax.xml.namespace.QName;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.endpoint.Endpoint;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import org.apache.cxf.service.model.BindingInfo;
import org.apache.cxf.service.model.BindingOperationInfo;
import org.apache.cxf.transport.http.HTTPConduit;
import org.apache.cxf.transports.http.configuration.HTTPClientPolicy;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import jws.service.User;
import util.JsonUtil;

/**
 * CXF 动态代理模式,不用生成本地WS代理类,
 * 通过反射调用 WS 的对应的方法,传入相应的参数
 * 访问cxf-server-web项目下的webservice;
 * 测试jaxws-rt发布WebService web方式。
 * 此测试实例,用于测试SEI和SIB的targetNamespace未指定的webService接口:
 * http://localhost:8080/cxf_server_web/jws_services?wsdl
 * @author donald
 * 2017年7月8日
 * 下午7:24:12
 */
public class CxfDynamicClientOnJwsRtWebWithQname {
	private static final Logger log = LoggerFactory.getLogger(CxfClient.class);
	private static final String JWS_RT_WSDL_URI = "http://localhost:8080/cxf_server_web/jws_services?wsdl";
	public static void main(String[] args) throws Exception {
		log.info("======CXF-WS Dynamic Client start!======");
		JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
		Client client =  dcf.createClient(JWS_RT_WSDL_URI);
		HTTPConduit conduit = (HTTPConduit)client.getConduit(); 
		HTTPClientPolicy policy = new HTTPClientPolicy(); 
		policy.setConnectionTimeout(10000); 
		policy.setAllowChunking(false); 
		policy.setReceiveTimeout(10000); 
		conduit.setClient(policy);	
		//获取操作对应的Qname
		QName operateQName = getOperateQName(client,"sum");
		//如果Qname已知,可以通过如下方式,直接创建QName
//		operateQName = new QName("http://service.jws/","login");
		Object[] invokeResult = client.invoke(operateQName, 17,8);	
		log.info("=======sumResult:" + invokeResult[0]);
		
		
	}
	/**
	 * 针对SEI和SIB不在统一个包内的情况,先查找操作对应的Qname,
	 * client通过Qname调用对应操作
	 * @param client
	 * @param operation
	 * @return
	 */
	private static QName getOperateQName(Client client,String operation){
		Endpoint endpoint = client.getEndpoint();  
		QName opName = new QName(endpoint.getService().getName().getNamespaceURI(), operation);  
		BindingInfo bindingInfo = endpoint.getEndpointInfo().getBinding();  
		if (bindingInfo.getOperation(opName) == null) {  
		    for (BindingOperationInfo operationInfo : bindingInfo.getOperations()) {  
		        if (operation.equals(operationInfo.getName().getLocalPart())) {  
		            opName = operationInfo.getName();  
		            break;  
		        }  
		    }  
		}
		log.info("Operation:"+operation+",namespaceURI:" + opName.getNamespaceURI());
		return opName;
	}
}

强烈建议使用第一种方式,符合规范。
