SOA 下实现分布式 调用 cxf+ webService +动态调用

   近期项目间隙 自学了  webservice   一下 是我写的  一个demo   

    首先我们在web.xml 里配置如下

     

<servlet>
    <servlet-name>CXFServlet</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>  //拦截qinqiu
  </servlet-mapping>

我用的  是maven项目 一下 pom.xml 引入一下依赖 

<dependency>

            <groupId>org.apache.cxf</groupId>

            <artifactId>cxf-rt-frontend-jaxws</artifactId>

            <version>2.7.14</version>

            <exclusions>

                <exclusion>

                    <groupId>asm</groupId>

                    <artifactId>asm</artifactId>

                </exclusion>

                <exclusion>

                    <groupId>com.sun.xml.bind</groupId>

                    <artifactId>jaxb-impl</artifactId>

                </exclusion>

 

            </exclusions>

        </dependency>

 

        <dependency>

            <groupId>org.apache.cxf</groupId>

            <artifactId>cxf-rt-transports-http</artifactId>

            <version>2.7.14</version>

        </dependency>

 

spring—cxf.xml 配置如下

动态调用  工具类

     */

    public static synchronized Object[] invoke(String wsdlUrl,String method,Object... params){

        

        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); 

        org.apache.cxf.endpoint.Client client = dcf.createClient(wsdlUrl); 

        

        Object[] objects = null;

        

        if(StringUtils.isEmpty(wsdlUrl)){

    

            logger.error("cxf 调用webservice 参数缺失：wsdl url 未传入");

            return objects;

        }

        

        if(StringUtils.isEmpty(method)){

            

            logger.error("cxf 调用webservice 执行方法名缺失：method 未传入");

            return objects;

        }

        

        try {

            } catch (Exception e) {

                e.printStackTrace();

                logger.error("cxf 调用webservice 执行错误：",e);
