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; /** * function:用axis实现RMI<a href="/tag/diaoyong/" target="_blank" class="keywords">调用</a> * @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 hoojo_@126.com * @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; /** * function: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 hoojo_@126.com * @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"> <p<a href="/tag/ara/" target="_blank" class="keywords">ara</a>meter name="className" value="com.hoo.rmi.impl.HelloRMIImpl" /> <p<a href="/tag/ara/" target="_blank" class="keywords">ara</a>meter name="allowedMethods" value="getAge,sayHello" /> <p<a href="/tag/ara/" target="_blank" class="keywords">ara</a>meter name="s<a href="/tag/cop/" target="_blank" class="keywords">cop</a>e" 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.<a href="/tag/remoteexception/" target="_blank" class="keywords">remoteexception</a>; 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; /** * function:axis WebService的RMI<a href="/tag/diaoyong/" target="_blank" class="keywords">调用</a>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 hoojo_@126.com * @version 1.0 */ public class HelloRMIClient { public static void main(String[] args) throws ServiceException,<a href="/tag/remoteexception/" target="_blank" class="keywords">remoteexception</a> { String url = "http://localhost:8080/AxisWebService/services/HelloRMI"; //axis call<a href="/tag/diaoyong/" target="_blank" class="keywords">调用</a> Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(url); call.s<a href="/tag/eto/" target="_blank" class="keywords">eto</a>perationName(new QName(url,"sayHello")); String result = (String) call.invoke(new Object[] { "jack" }); Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.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); Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.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。
