XFire中的Handler处理

同样，我们还是把Web服务端和客户端分成两个项目，来写

下面展示的是Web服务端的代码

首先是web.xml和services.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping></web-app><?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://xfire.codehaus.org/config/1.0"><service><name>XFireHandlerDemo</name><namespace>http://www.jadyer.com/XFireHandlerDemo</namespace><serviceClass>com.jadyer.server.HelloService</serviceClass><implementationClass>com.jadyer.server.HelloServiceImpl</implementationClass><!-- 请留意下面的设置 --><inHandlers><handler handlerClass="com.jadyer.server.handler.ServerInHandler"/></inHandlers><outHandlers><handler handlerClass="com.jadyer.server.handler.ServerOutHandler"/></outHandlers></service></beans>

接着是Web服务暴露的接口及其实现类

package com.jadyer.server;public interface HelloService {public String sayHello(String message);}package com.jadyer.server;public class HelloServiceImpl implements HelloService {public String sayHello(String message) {return message;}}

然后是Web服务端前置的Handler类

package com.jadyer.server.handler;import org.codehaus.xfire.MessageContext;import org.codehaus.xfire.handler.AbstractHandler;/** * Web服务端前置的Handler类 */public class ServerInHandler extends AbstractHandler {public void invoke(MessageContext ctx) throws Exception {System.out.println("ServerInHandler is Invoked...");ctx.setProperty("myServerParam", "ServerInHandler传递的参数");System.out.println("ServerInHandler is Exit...");}}

最后是Web服务端后置的Handler类

package com.jadyer.server.handler;import org.codehaus.xfire.MessageContext;import org.codehaus.xfire.handler.AbstractHandler;/** * Web服务端后置的Handler类 */public class ServerOutHandler extends AbstractHandler {public void invoke(MessageContext ctx) throws Exception {System.out.println("ServerOutHandler is Invoked...");System.out.println(ctx.getProperty("myServerParam"));System.out.println("ServerOutHandler is Exit...");}}

Web服务端，至此完毕

下面是客户端代码，我这里另建一个Java Project

首先是客户端前置的Handler类

package com.jadyer.client.handler;import org.codehaus.xfire.MessageContext;import org.codehaus.xfire.handler.AbstractHandler;/** * 客户端前置的Handler类 */public class ClientOutHandler extends AbstractHandler {public void invoke(MessageContext ctx) throws Exception {System.out.println("ClientOutHandler is Invoked...");ctx.setProperty("myClientParam", "ClientOutHandler传递的参数");System.out.println("ClientOutHandler is Exit...");}}

然后是客户端后置的Handler类

package com.jadyer.client.handler;import org.codehaus.xfire.MessageContext;import org.codehaus.xfire.handler.AbstractHandler;/** * 客户端后置的Handler类 */public class ClientInHandler extends AbstractHandler {public void invoke(MessageContext ctx) throws Exception {System.out.println("ClientInHandler is Invoked...");System.out.println(ctx.getProperty("myClientParam"));System.out.println("ClientInHandler is Exit...");}}

最后是客户端的测试代码

package com.jadyer.client;import java.net.MalformedURLException;import org.codehaus.xfire.client.Client;import org.codehaus.xfire.client.XFireProxyFactory;import org.codehaus.xfire.service.Service;import org.codehaus.xfire.service.binding.ObjectServiceFactory;import com.jadyer.client.handler.ClientInHandler;import com.jadyer.client.handler.ClientOutHandler;import com.jadyer.server.HelloService;/** * 客户端测试代码 * @see 假设此时Web服务端为我们提供接口了 * @see 此时客户端需要引入MyEclipse提供的XFire 1.2 Core、HTTP Client Libraries两个类库 * @see 其中关于客户端的ClientOutHandler.java和ClientInHandler.java是由我们在客户端上手工创建的 */public class HandlerTest {private static final String url = "http://127.0.0.1:8080/XFire_Handler/services/XFireHandlerDemo";private static final String namespace = "http://www.jadyer.com/XFireHandlerDemo";public static void main(String[] args) {Service serviceModel = new ObjectServiceFactory().create(HelloService.class, null, namespace, null);try{HelloService clientService = (HelloService)new XFireProxyFactory().create(serviceModel, url);Client client = Client.getInstance(clientService);client.addInHandler(new ClientInHandler());client.addOutHandler(new ClientOutHandler());System.out.println(clientService.sayHello("测试成功"));}catch(MalformedURLException e){e.printStackTrace();}}}/******【当运行该类进行测试时，客户端的控制台上会输出以下内容】******///ClientOutHandler is Invoked...//ClientOutHandler is Exit...//ClientInHandler is Invoked...//ClientOutHandler传递的参数//ClientInHandler is Exit...//测试成功/******【当运行该类进行测试时，服务端的控制台上会输出以下内容】******///ServerInHandler is Invoked...//ServerInHandler is Exit...//ServerOutHandler is Invoked...//ServerInHandler传递的参数//ServerOutHandler is Exit.../******★★此时我们视其为Handler测试成功★★*********************/
