CXF拦截器和自定义拦截器

1. CXF添加拦截器

webservice分服务端和客户端，服务端和客户端都是可以加拦截器的，无论是服务端还是客户端，都分进，出(In，Out)拦截器；

Server.java

package com.andrew.server;

import javax.xml.ws.Endpoint;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

import com.andrew.webservice.HelloWorld;
import com.andrew.webservice.impl.HelloWorldImpl;

public class Server {
    public static void main(String[] args) {
        System.out.println("web service start");
        HelloWorld implementor = new HelloWorldImpl();
        String address = "http://192.168.18.2/helloWorld";
        // 1. 使用JDK实现
        // Endpoint.publish(address, implementor);
        // 2. 使用CXF实现
        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 LoggingOutInterceptor()); // 添加out拦截器
        factoryBean.create();
        System.out.println("web service started");
    }
}

        client.getInInterceptors().add(new LoggingInInterceptor()); // 添加in拦截器 日志拦截器

        System.out.println(helloWorld.say("andrew"));
        User user = new User();
        user.setUserName("tony");
        user.setPassword("123456");
        List roleList = helloWorld.getRoleByUser(user);
        for (Role role : roleList) {

        }
        MyRoleArray array = helloWorld.getRoles();
        List roleList2 = array.getItem();
        for(int i = 0; i < roleList2.size(); i++){
            MyRole my = roleList2.get(i);
            System.out.print(my.getKey() + ":");
            for(Role r : my.getValue()){
                System.out.print(r.getId() + "," + r.getRoleName() + " ");
            }
            System.out.println();
        }
    }
}

2. CXF添加自定义拦截器

MyInterceptor.java

package com.andrew.interceptor;

import org.w3c.dom.NodeList;

public class MyInterceptor extends AbstractPhaseInterceptor{

    public MyInterceptor() {
        super(Phase.PRE_INVOKE);
    }
 
    public void handleMessage(SoapMessage message) throws Fault {
        List
 headers = message.getHeaders();
        if (headers == null || headers.size() == 0) {
            throw new Fault(new IllegalArgumentException("没有Header,拦截器实施拦截"));
        }
        Header firstHeader = headers.get(0);
        Element ele = (Element) firstHeader.getObject();
        NodeList userIds = ele.getElementsByTagName("userName");
        NodeList userPasses = ele.getElementsByTagName("password");
        if (userIds.getLength() != 1) {
            throw new Fault(new IllegalArgumentException("用户名格式不对"));
        }
        if (userPasses.getLength() != 1) {
            throw new Fault(new IllegalArgumentException("密码格式不对"));
        }
        String userId = userIds.item(0).getTextContent();
        String userPass = userPasses.item(0).getTextContent();
        if (!userId.equals("tony") || ! userPass.equals("123456")) {
            throw new Fault(new IllegalArgumentException("用户名或者密码不正确"));
        }
    }
}

        HelloWorld helloWorld = service.getHelloWorldPort();
        org.apache.cxf.endpoint.Client client = ClientProxy.getClient(helloWorld);
        // client.getInInterceptors().add(new LoggingInInterceptor()); // 添加in拦截器 日志拦截器
        client.getOutInterceptors().add(new AddHeaderInterceptor("tony","123456")); // 添加自定义拦截器
        client.getOutInterceptors().add(new LoggingOutInterceptor()); // 添加out拦截器
        System.out.println(helloWorld.say("andrew"));
        User user = new User();
        user.setUserName("tony");
        user.setPassword("123456");
        List roleList = helloWorld.getRoleByUser(user);
        for (Role role : roleList) {
            System.out.println(role.getId() + "," + role.getRoleName());
        }
        MyRoleArray array = helloWorld.getRoles();
        List roleList2 = array.getItem();
        for(int i = 0; i < roleList2.size(); i++){
            MyRole my = roleList2.get(i);
            System.out.print(my.getKey() + ":");
            for(Role r : my.getValue()){
                System.out.print(r.getId() + "," + r.getRoleName() + " ");
            }
            System.out.println();
        }
    }
}

如果密码改成123则报错
