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; /** * @author xdwang * * @create Apr 25, 2013 10:35:50 PM * * @email:xdwangiflytek@gmail.com * * @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:
