今天開始講下攔截器，前面你們學過servlet，struts2 都有攔截器概念，主要做用是作一些權限過濾，編碼處理等；html

webservice也能夠加上攔截器，咱們能夠給webservice請求加權限判斷功能；java

webservice分服務端和客戶端，服務端和客戶端都是能夠加攔截器的，不管是服務端仍是客戶端，都分進，出（In，Out）攔截器；程序員

咱們先來改下服務端的Server類：web

package com.wishwzp.webservice;

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.wishwzp.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://192.168.0.110/helloWorld";  
        //Endpoint.publish(address, implementor);  // JDK實現   暴露webservice接口
        JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
        factoryBean.setAddress(address); // 設置暴露地址
        factoryBean.setServiceClass(HelloWorld.class); // 接口類
        factoryBean.setServiceBean(implementor); // 設置實現類
        factoryBean.getInInterceptors().add(new LoggingInInterceptor()); // 添加in攔截器 日誌攔截器
        factoryBean.getOutInterceptors().add(new LoggingOutInterceptor()); // 添加out攔截器
        factoryBean.create();
        System.out.println("web service started");  
    }
}

這裏的話，咱們經過factoryBean對象能夠獲取攔截器組，添加進或者出攔截器，這裏有個經典的攔截器，咱們開發的時候常常用，就是日誌攔截器，apache

咱們能夠把客戶端的請求，以及服務端返回的信息打印出來，能夠打印控制檯，也能夠打印到執行文件；這裏爲了演示方便，直接搞無參的攔截器，架構

打印到控制檯； frontend

不管是自定義的攔截器，仍是CXF自帶的攔截器，都必須實現Interceptor接口。svn

咱們執行下Server類：測試

而後咱們再來執行下客戶端的Client類，結果：ui

而後咱們仔細觀察Server端的控制檯:

這裏的打印出來的就是日誌信息：Inbound 進信息 Outbound 是出信息，進的時候，你們會看到有個Headers SOAP消息。後面咱們能夠在裏面加咱們的數據；

在Outbound Message裏，Payload消息裏咱們能夠找到webservice返回的數據 SOAP消息；

同理，咱們在客戶端也能夠加進出攔截器，修改Client代碼：

package com.wishwzp.webservice;

import java.util.List;

import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;

public class Client {
    
    public static void main(String[] args) {
        HelloWorldService service=new HelloWorldService();
        HelloWorld helloWorld=service.getHelloWorldPort();
        
        org.apache.cxf.endpoint.Client client=ClientProxy.getClient(helloWorld);
        client.getInInterceptors().add(new LoggingInInterceptor()); // 添加in攔截器 日誌攔截器
        client.getOutInterceptors().add(new LoggingOutInterceptor()); // 添加out攔截器
        
        //System.out.println(helloWorld.say("wishwzp測試"));
//        User user=new User();
//        user.setUserName("jack");
//        user.setPassword("123456");
//        List<Role> roleList=helloWorld.getRoleByUser(user);
//        for(Role role:roleList){
//            System.out.println(role.getId()+","+role.getRoleName());
//        }
        MyRoleArray array=helloWorld.getRoles();
        List<MyRole> roleList=array.item;
        for(int i=0;i<roleList.size();i++){
            MyRole my=roleList.get(i);
            System.out.print(my.key+":");
            for(Role r:my.value){
                System.out.print(r.getId()+","+r.getRoleName()+" ");
            }
            System.out.println();
        }
    }

}

這裏的話，咱們用到了ClientProxy，客戶端代理。因此也是須要導入對應cxfjar包的，這裏我直接將pox.xml的複製到client項目中

  <dependencies>
  
      <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-core</artifactId>
        <version>3.1.5</version>
    </dependency>

        <artifactId>cxf-rt-transports-http-jetty</artifactId>
        <version>3.1.5</version>
    </dependency>
    
  </dependencies>

咱們請求的時候，能夠看到控制檯的日誌信息：

這裏也是出進的日誌信息，和上面那個相似；

OK到這裏的話，添加攔截器已經講完了；
