XML：No operation was found with the name报错解决办法

当我们使用CXF动态客户端调用WebService接口容易出现如下问题：命名空间问题

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。

解决办法：

SIB的targetNamespace的命名空间为SEI对应的命名空间targetNamespace相同即可。

SEI (interface接口类)：

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/

 */
@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);

}

SBI (implements接口实现类)：

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;
    }
}

 

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；

 */
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]);
    }
}
