  • 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;
     * @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]);
        }
    }
