七、axis调用RMI模式WebService

和先前写的web service几乎一样，不同的是这里写的WebService要实现接口，而我们实现的接口要继承rmi的Remote接口才行。

1、RMI接口，很简单的2个方法，继承Remote接口

 package com.hoo.rmi;import java.rmi.Remote;/** * <b>function:</b>用axis实现RMI调用 * @author hoojo * @createDate Dec 16, 2010 16:22:25 PM * @file HelloRMI.java * @package com.hoo.rmi * @project AxisWebService * @blog http://blog.csdn.net/IBM_hoojo * @email [e-mail] * @version 1.0 */public interface HelloRMI extends Remote { public String sayHello(String name); public int getAge(int age);} 

2、实现上面的接口

 package com.hoo.rmi.impl;import com.hoo.rmi.HelloRMI;/** * <b>function:</b>实现RMI服务器接口 * @author hoojo * @createDate Dec 16, 2010 16:23:15 PM * @file HelloRMIImpl.java * @package com.hoo.rmi.impl * @project AxisWebService * @blog http://blog.csdn.net/IBM_hoojo * @email [e-mail] * @version 1.0 */public class HelloRMIImpl implements HelloRMI { public int getAge(int age) { return age + 10; } public String sayHello(String name) { return name + " say: hello rmi WebService !"; }} 

 

 

 

3、定制wsdd发布服务

 <?xml version="1.0" encoding="UTF-8"?><deployment xmlns="http://xml.apache.org/axis/wsdd/"xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"><service name="HelloRMI" provider="java:RPC"><parameter name="className" value="com.hoo.rmi.impl.HelloRMIImpl" /><parameter name="allowedMethods" value="getAge,sayHello" /><parameter name="scope" value="request" /></service></deployment> 

 

 

4、命令行发布服务

java -Djava.ext.dirs=lib org.apache.axis.client.AdminClient -lhttp://localhost:8080/AxisWebService/services/AdminService deployRMI.wsdd

在浏览器中输入：

http://localhost:8080/AxisWebService/servlet/AxisServlet

即可查看到刚才发布的服务

 

5、编写客户端调用代码

 package com.hoo.client;import java.rmi.RemoteException;import javax.xml.namespace.QName;import javax.xml.rpc.ServiceException;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import com.hoo.rmi.HelloRMI;/** * <b>function:</b>axis WebService的RMI调用模式 * @author hoojo * @createDate Dec 16, 2010 16:28:09 PM * @file HelloRMIClient.java * @package com.hoo.client * @project AxisWebService * @blog http://blog.csdn.net/IBM_hoojo * @email [e-mail] * @version 1.0 */public class HelloRMIClient { public static void main(String[] args) throws ServiceException, RemoteException { String url = "http://localhost:8080/AxisWebService/services/HelloRMI"; //axis call调用 Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(url); call.setOperationName(new QName(url, "sayHello")); String result = (String) call.invoke(new Object[] { "jack" }); System.out.println(result); //远程接口模式，只管接口不管实现，这就是面向接口的好处 HelloRMI rmi = (HelloRMI) service.getPort(url, HelloRMI.class); System.out.println(rmi.getAge(22)); }} 

 

 

HelloRMI rmi = (HelloRMI) service.getPort(url, HelloRMI.class);

用rmi接口调用的还是比较简单明了，接口中的方法都一目了然。我们也不用操心接口里面的方法是怎么样实现的，更具有面向接口编程、更加透明化。
