CXF 调用方式——动态创建客户端（调用稳定版本号为2.7.18）

今天用动态创建客户端的方式调用webservice，报了这样一个错：

服务端是没有问题的，用url调用可以正常执行。

最后通过更改我们的CXF版本解决了这个问题：

之前的版本：2.6.2

修改后的版本：2.7.18，试了用3.X.X表示不行

因为是用的maven所以该版本比较方便，如下：

常量

<properties>
    <cxf.version>2.7.18</cxf.version>
  </properties>

dependency

        
        <!-- CXF WEBSERVICE -->
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>${cxf.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>${cxf.version}</version>
        </dependency>
        <!-- CXF WEBSERVICE END  -->

服务端和客户端最好统一，如果只改客户端（cxf-rt-frontend-jaxws）为2.7.18也是可以的

最后附一个动态调用示例写法：

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

import com.alibaba.fastjson.JSON;

import javax.xml.bind.*;

/**
 * @ClassName: WebServiceTest
 * @Description: TODO
 * @author: liuyx 
 * @date: 2015年9月27日下午5:22:15
 */
public class WebServiceTest {
    private static final String testUrl = "http://172.16.10.87/platform3.0/webService/TestWebservice?wsdl";
    public static void main(String[] args) throws Exception {
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient(testUrl);
        
        Object[] objects=client.invoke("testOut", "test"); 
        //输出调用结果
        System.out.println(JSON.toJSONString(objects));
    }
}
