（五） CXF 拦截器--系统拦截器

【1. 简介】

WS 服务一般需要进行权限限制， 否则的话任何都可以随意调用。 如果使用原生的JDK 发布WS服务，程序员需要对SOAP 消息进行解析，然后进行判断。使用CXF 后，CXF框架可以帮助我们进行SOAP 消息的解析和生成，这样开发起来就更简单了。

WS拦截器分为入拦截器和出拦截器，无论是服务端和客户端都有这两种拦截器。 CXF 提供了一些默认的系统拦截器，如日志拦截器。 此篇文章主要介绍 CXF 提供的日志拦截器。CXF拦截器图：



【2. 示例】

【1. 服务器端】 服务器端启动日志入拦截器和日志出拦截器

package org.zgf.cxf.test.o2;

import java.util.List;

import javax.xml.ws.Endpoint;

import org.apache.cxf.interceptor.Interceptor;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws22.EndpointImpl;
import org.apache.cxf.message.Message;
import org.zgf.cxf.server.HelloWordWS;

/**
* 测试 ws 服务器发布
*/
public class TestPublishServer {

public static void main(String[] args) {
//1. 设置发布地址：ip 需要为本机ip， 端口号为本机未被占用的端口号
String address = "http://172.22.12.85:8180/ws/hellowordws";
Endpoint endpoint = Endpoint.publish(address, new HelloWordWS());
EndpointImpl endpointImpl = (EndpointImpl)endpoint;

//2. 获取入拦截器列表，默认为null，并添加cxf提供的日志人拦截器
List<Interceptor<? extends Message>> inInterCeptors = endpointImpl.getInInterceptors();
inInterCeptors.add(new LoggingInInterceptor());

//3. 获取出拦截器列表，默认为null，并添加cxf提供的日志出拦截器
List<Interceptor<? extends Message>> outInterCeptors = endpointImpl.getOutInterceptors();
outInterCeptors.add(new LoggingOutInterceptor());

System.out.println("web service 接口发布成功... ");
}
}

【2. 客户端】 客户端启动日志入拦截器和日志出拦截器

package org.zgf.cxf.test.o2;

import java.util.List;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.Interceptor;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.message.Message;
import org.zgf.cxf.client.HelloWordWSService;
import org.zgf.cxf.client.IHelloWorldWS;

public class Test_client {
public static void main(String[] args) {
//1. 创建服务代理工厂（继承 javax.xml.ws.Service 的类）
HelloWordWSService hwws = new HelloWordWSService();
//2. 创建服务代理
IHelloWorldWS hws = hwws.getHelloWordWSPort();

//3. 获取Client 对象
Client client = ClientProxy.getClient(hws);

//4. 获取入参拦截器列表，默认为null，添加cxf 自带的日志入拦截器
List<Interceptor<? extends Message>> inInterCeptors = client.getInInterceptors();
inInterCeptors.add(new LoggingInInterceptor());

//5. 获取出拦截器列表，默认为null，添加cxf自带的日志出拦截器
List<Interceptor<? extends Message>> outInterCeptors = client.getOutInterceptors();
outInterCeptors.add(new LoggingOutInterceptor());

String result = hws.sayByeBye("zong");
System.out.println("result:" + result);

}

}

【5. 总结】

添加CXF系统提供的日志拦截器后，可以清楚地看出调用WS服务的时候发送的参数，包括http请求的相关参数：请求行，请求头，请求体； 当然了还能清楚地看出调用WS接口方法时，发送的SOAP消息体和SOAP 响应的消息体。
