XML：No operation was found with the name報錯解決辦法

當我們使用CXF動態客戶端調用WebService接口容易出現如下問題：命名空間問題

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)

這個問題是由這個問題因為SIB和SEI類的targetNamespace統一導致的。

解決辦法：

SIB的targetNamespace的命名空間為SEI對應的命名空間targetNamespace相同即可。

SEI (interface接口類)：

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
 * 如果返回結果時實例類，則targetNamespace必須用http://service.jws/，即http://+SEI倒序報名+/
 * 沒有的話可以，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注解可寫可不寫
//    @WebMethod 
    @WebResult(name="sumResult")
    public int sum(@WebParam(name="firstNum")int firstNum,
            @WebParam(name="secondNum")int secondNum);

}

SBI (implements接口實現類)：

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接口實現
 * 注意這里的targetNamespace的命名空間為SEI對應的命名空間，注意最后要加/
 * 否則利用CXF動態客戶端調用時，會找不到
 * 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;
    }
}

 

動態客戶端：

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 動態代理模式，不用生成本地WS代理類，
 * 通過反射調用 WS 的對應的方法，傳入相應的參數
 * 訪問cxf-server-web項目下的webservice;
 * 測試jaxws-rt發布WebService web方式。
 * 此測試實例，用於測試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]);
    }
}
