学习webservice之cxf（7）：cxf自定义拦截器

server方法中

package com.rg2.webservice.impl;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

import com.rg2.intercepter.MyIntercepter;
import com.rg2.webservice.HelloWorld;

public class Server {

    public static void main(String[] args) {
        System.out.println("web service start");
        HelloWorld implementor = new HelloWorldImpl();
        String address = "http://localhost/helloWorld";
//        Endpoint.publish(address, implementor);//jdk实现暴露webservice接口
        JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
        factoryBean.setAddress(address);//设置暴露地址
        factoryBean.setServiceClass(HelloWorld.class);//接口类
        factoryBean.setServiceBean(implementor);//设置实现类
        factoryBean.getInInterceptors().add(new LoggingInInterceptor());//添加in拦截器 日志拦截器
        factoryBean.getOutInterceptors().add(new LoggingInInterceptor());//添加out拦截器 日志拦截器
        
        factoryBean.getInInterceptors().add(new MyIntercepter());
        factoryBean.create();//创建webservice接口
        System.out.println("web service started");
    }

}

Client

        client.getOutInterceptors().add(new AddHeaderIntercepter("rg2","123456"));//添加自定义拦截器
        client.getInInterceptors().add(new LoggingInInterceptor());//添加in拦截器 日志拦截器
        client.getOutInterceptors().add(new LoggingInInterceptor());//添加out拦截器 日志拦截器
        
        MyRoleArray getroles = helloWorldPort.getroles();

        for (int i = 0; i < roleList.size(); i++) {
