  • (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:

    web service start

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

    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
    信息: Creating Service {http://webservice.wishwzp.com/}HelloWorldService from WSDL: http://192.168.0.110/helloWorld?wsdl

    Headers: {Accept=[*/*], SOAPAction=[""]}
    Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:getRoles xmlns:ns2="http://webservice.wishwzp.com/"/></soap:Body></soap:Envelope>

    --------------------------------------
    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;
