Java WebService CXF Interceptor

今天我们来说一下CXF的Interceptor，其主要功能就是在每个请求响应之前或响应之后，做一些事情。这里的Interceptor就和Filter、Struts的Interceptor很类似，提供它的主要作用就是为了很好的降低代码的耦合性，提供代码的内聚性。下面我们就看看CXF的Interceptor是怎么样工作的。

1、我们就用上篇博客中的HelloWorldService，客户端的调用代码重新写一份，代码如下：

package com.iflytek.client;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.iflytek.service.IHelloWorldService;

/**

 * 
 * @description CXF WebService客户端调用代码
 * 
 */
public class ServiceMessageInterceperClient {
	public static void main(String[] args) { // 调用WebService
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.setServiceClass(IHelloWorldService.class);
		factory.setAddress("http://localhost:8000/helloWorld");
		
		factory.getInInterceptors().add(new LoggingInInterceptor());
		factory.getOutInterceptors().add(new LoggingOutInterceptor());
		
		IHelloWorldService service = (IHelloWorldService) factory.create();
		System.out.println("[result]" + service.sayHello("xdwang"));
	}
}

上面的CXF的拦截器是添加在客户端，同样在服务器端也是可以添加拦截器Interceptor的。运行后结果如下：

2013-7-25 19:22:42 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://service.iflytek.com/}IHelloWorldServiceService from class com.iflytek.service.IHelloWorldService
2013-7-25 19:22:43 org.apache.cxf.services.IHelloWorldServiceService.IHelloWorldServicePort.IHelloWorldService
信息: Outbound Message
---------------------------
ID: 1
Address: http://localhost:8000/helloWorld
Encoding: UTF-8
Http-Method: POST
Content-Type: text/xml
Headers: {Accept=[*/*], SOAPAction=[""]}
Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:sayHello xmlns:ns2="http://service.iflytek.com/"><name>xdwang</name></ns2:sayHello></soap:Body></soap:Envelope>
--------------------------------------
2013-7-25 19:22:43 org.apache.cxf.services.IHelloWorldServiceService.IHelloWorldServicePort.IHelloWorldService
信息: Inbound Message
----------------------------
ID: 1
Response-Code: 200
Encoding: UTF-8
Content-Type: text/xml;charset=UTF-8
Headers: {Content-Length=[235], content-type=[text/xml;charset=UTF-8], Server=[Jetty(8.1.7.v20120910)]}
Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns1:sayHelloResponse xmlns:ns1="http://service.iflytek.com/"><return>xdwang say: Hello World </return></ns1:sayHelloResponse></soap:Body></soap:Envelope>
--------------------------------------
[result]xdwang say: Hello World

上面的部分信息是LoggingInterceptor输出的日志信息，分别在请求和响应的时候输出日志信息，还有输出请求的时候参数的信息以及响应的时候返回值的信息。

2、刚才是客户端添加Interceptor，现在我们自己编写一个Interceptor，这个Interceptor需要继承AbstractPhaseInterceptor，实现handleMessage和一个带参数的构造函数。然后在服务器端添加这个Interceptor。

Interceptor代码如下：

package com.iflytek.interceptor;

import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.message.Message;
import org.apache.cxf.phase.AbstractPhaseInterceptor;

/**
 * @author xdwang
 * 
 * @create 2013-7-25 下午7:24:12
 * 
 * @email:xdwangiflytek@gmail.com
 * 
 * @description 自定义消息拦截器
 * 
 */
public class MessageInterceptor extends AbstractPhaseInterceptor<Message> {
	// 至少要一个带参的构造函数
	public MessageInterceptor(String phase) {
		super(phase);
	}

	public void handleMessage(Message message) throws Fault {
		System.out.println("============handleMessage==========");
		System.out.println(message);
		if (message.getDestination() != null) {
			System.out.println(message.getId() + "=" + message.getDestination().getMessageObserver());
		}
		if (message.getExchange() != null) {
			System.out.println(message.getExchange().getInMessage() + "=" + message.getExchange().getInFaultMessage());
			System.out
					.println(message.getExchange().getOutMessage() + "=" + message.getExchange().getOutFaultMessage());
		}
	}
}

下面看看发布服务和添加自定义拦截器的代码：

package com.iflytek.service.deploy;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
import org.apache.cxf.phase.Phase;

import com.iflytek.interceptor.MessageInterceptor;
import com.iflytek.service.HelloWorldService;

/**
 * @author xdwang
 * 
 * @create 2013-7-25 下午7:25:55
 * 
 * @email:xdwangiflytek@gmail.com
 * 
 * @description 在服务器发布自定义的Interceptor
 * 
 */
public class DeployInterceptorService {
	public static void main(String[] args) throws InterruptedException {
		// 发布WebService
		JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
		// 设置Service Class
		factory.setServiceClass(HelloWorldService.class);
		factory.setAddress("http://localhost:9000/helloWorld");
		// 设置ServiceBean对象
		factory.setServiceBean(new HelloWorldService());
		// 添加请求和响应的拦截器，Phase.RECEIVE只对In有效，Phase.SEND只对Out有效
		factory.getInInterceptors().add(new MessageInterceptor(Phase.RECEIVE));
		factory.getOutInterceptors().add(new MessageInterceptor(Phase.SEND));
		factory.create();
		System.out.println("Server start ......");
		Thread.sleep(1000 * 60);
		System.exit(0);
		System.out.println("Server exit ");
	}
}

值得说的是，以前发布WebService是用Endpoint的push方法。这里用的是JaxWsServerFactoryBean和客户端调用的代码JaxWsProxyFactoryBean有点不同。

package com.iflytek.client;

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.iflytek.service.IHelloWorldService;

/**
 * @author xdwang
 * 
 * @create 2013-7-25 下午7:28:18
 * 
 * @email:xdwangiflytek@gmail.com
 * 
 * @description CXF WebService客户端调用代码
 * 
 */
public class HelloWorldServiceClient {
	public static void main(String[] args) {
		// 调用WebService
		JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
		factory.setServiceClass(IHelloWorldService.class);
		factory.setAddress("http://localhost:9000/helloWorld");
		IHelloWorldService service = (IHelloWorldService) factory.create();
		System.out.println("[result]" + service.sayHello("hoojo"));
	}
}

运行结果：
