(七)CXF添加拦截器

今天开始讲下拦截器,前面大家学过servlet,struts2 都有拦截器概念,主要作用是做一些权限过滤,编码处理等;

 

webservice也可以加上拦截器,我们可以给webservice请求加权限判断功能;

 

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;

 

我们先来改下服务端的Server类:

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 LoggingOutInterceptor()); // 添加out拦截器
        factoryBean.create();
        System.out.println("web service started");  
    }
}

 

这里的话,我们通过factoryBean对象可以获取拦截器组,添加进或者出拦截器,这里有个经典的拦截器,我们开发的时候经常用,就是日志拦截器,

我们可以把客户端的请求,以及服务端返回的信息打印出来,可以打印控制台,也可以打印到执行文件;这里为了演示方便,直接搞无参的拦截器,

打印到控制台; 

 

无论是自定义的拦截器,还是CXF自带的拦截器,都必须实现Interceptor接口。

 

我们执行下Server类:

 

然后我们再来执行下客户端的Client类,结果:

然后我们仔细观察Server端的控制台:

--------------------------------------

 

这里的打印出来的就是日志信息:Inbound 进信息  Outbound 是出信息,进的时候,大家会看到有个Headers SOAP消息。后面我们可以在里面加我们的数据;

在Outbound Message里,Payload消息里我们可以找到webservice返回的数据 SOAP消息;

 

 

同理,我们在客户端也可以加进出拦截器,修改Client代码:

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拦截器 日志拦截器
        client.getOutInterceptors().add(new LoggingOutInterceptor()); // 添加out拦截器
        
        //System.out.println(helloWorld.say("wishwzp测试"));
//        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();
        }
    }

}

这里的话,我们用到了ClientProxy,客户端代理。所以也是需要导入对应cxfjar包的,这里我直接将pox.xml的复制到client项目中

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

      <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>3.1.5</version>
    </dependency>
    
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-transports-http-jetty</artifactId>
        <version>3.1.5</version>
    </dependency>
    
  </dependencies>

 

我们请求的时候,可以看到控制台的日志信息:

十一月 06, 2018 5:28:44 下午 org.apache.cxf.wsdl.service.factory.ReflectionServiceFactoryBean buildServiceFromWSDL

--------------------------------------
wishwzp:1,技术总监 2,架构师 
jack:1,程序员 

 

这里也是出进的日志信息,和上面那个类似;

 

OK到这里的话,添加拦截器已经讲完了;
