Spring整合Rmi总结
在Spring整合Rmi中:
服务端使用了org.springframework.remoting.rmi.RmiServiceExporter
RmiServiceExporter把任何Spring管理的Bean输出成一个RMI服务。通过把Bean包装在一个适配器类中工作。适配器类被绑定到RMI注册表中，并且将请求代理给服务类。
客户端使用了org.springframework.remoting.rmi.RmiProxyFactoryBean
客户端的核心是RmiProxyFactoryBean，包含serviceURL属性和serviceInterface属性。
通过JRMP访问服务。JRMP JRMP:java remote method protocol，Java特有的,基于流的协议。
下面给出简单例子
服务端程序：
新建接口：
/** * IRmiServer.java * 版权所有(C) 2012 * 创建:cuiran 2012-08-08 11:12:40 */package com.cayden.rmi;/** * TODO * @author cuiran * @version TODO */public interface IRmiServer {public boolean test();}
再实现该接口的方法：
/** * RmiServerImpl.java * 版权所有(C) 2012 * 创建:cuiran 2012-08-08 11:13:24 */package com.cayden.rmi.impl;import com.cayden.rmi.IRmiServer;/** * TODO * @author cuiran * @version TODO */public class RmiServerImpl implements IRmiServer {/* (non-Javadoc) * @see com.cayden.rmi.IRmiServer#test() */@Overridepublic boolean test() {System.out.println("调用了我--服务端 O(∩_∩)O哈！");return true;}}
在src下新建applicationContext.xml 配置文件
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.5//EN" "file:/usr/local/tomcat_report/lib/spring-beans-2.0.dtd"><beans><!-- rmi --><bean id="rmiService" class="com.cayden.rmi.impl.RmiServerImpl"></bean><bean id="remoteRmiService" class="org.springframework.remoting.rmi.RmiServiceExporter"><property name="serviceName"><value>remoteService</value></property><property name="service" ref="rmiService" /><property name="serviceInterface"><value>com.cayden.rmi.IRmiServer</value></property><property name="registryPort"><value>9400</value></property><property name="servicePort"><value>9401</value></property></bean></beans>
启动服务端的类【MainServer.java】
package com.cayden.rmi;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * MainServer.java * 版权所有(C) 2012 * 创建:cuiran 2012-08-08 11:44:07 *//** * TODO * @author cuiran * @version TODO */public class MainServer {/** * TODO * @param args */public static void main(String[] args) {// TODO Auto-generated method stubSystem.out.println("rmi服务端启动"); ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); System.out.println("rmi服务端启动完成。。。");}}
客户端代码：
在客户端使用服务端的接口文件：
/** * IRmiServer.java * 版权所有(C) 2012 * 创建:cuiran 2012-08-08 11:12:40 */package com.cayden.rmi;/** * TODO * @author cuiran * @version TODO */public interface IRmiServer {public boolean test();}
然后在src下新建【applicationContext.xml】
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.5//EN" "file:/usr/local/tomcat_report/lib/spring-beans-2.0.dtd"><beans><!-- rmi远程调用 --><bean id="testRmiService" class="org.springframework.remoting.rmi.RmiProxyFactoryBean"><property name="serviceUrl"><value>rmi://127.0.0.1:9400/remoteService</value></property><property name="serviceInterface"><value>com.cayden.rmi.IRmiServer</value></property></bean></beans>
最新新建客户端的测试类【TestRmi.java】
/** * TestRmi.java * 版权所有(C) 2012 * 创建:cuiran 2012-08-08 11:38:06 */package com.cayden.rmi.client;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.cayden.rmi.IRmiServer;/** * TODO * @author cuiran * @version TODO */public class TestRmi {public static void main(String[] arg) {System.out.println("rmi客户端开始调用"); ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); IRmiServer rmi=(IRmiServer)ctx.getBean("testRmiService"); rmi.test(); System.out.println("rmi客户端调用结束");}}
最后控制台输出
服务端：
rmi服务端启动log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).log4j:WARN Please initialize the log4j system properly.rmi服务端启动完成。。。调用了我--服务端 O(∩_∩)O哈！
客户端：

由于例子详细需要源码的请留下邮箱,谢谢！
