spring RMI的使用

Spring整合RMI的原理

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。

 

服务端暴露远程服务

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。

 

 

RMI服务端实现类

package com.impl;import com.interfaces.IHelloWord;/** * Created by lunhui.wei on 2014/11/7. */public class HelloWorld implements IHelloWord{    @Override    public String helloWorld() {        return "Hello World";    }    @Override    public String sayHelloToSomeBody(String name) {        return name+" say:"+" Hello world";    }}

服务端RMI接口类

public interface IHelloWord {    public String helloWorld();    public String sayHelloToSomeBody(String  name);}

服务端运行类

package com;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * Created by lunhui.wei on 2014/11/7. */public class Run {    public static void main(String args[]){        ApplicationContext applicationContext=new ClassPathXmlApplicationContext("spring-config.xml");        System.out.println("RMI服务伴随Spring的启动而启动了.....");    }}

服务端spring-config.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="helloWorld" class="com.impl.HelloWorld"/>    <bean id="serviceExporter" class="org.springframework.remoting.rmi.RmiServiceExporter">        <property name="service" ref="helloWorld"/>        <property name="serviceName" value="hello"/>        <property name="serviceInterface" value="com.interfaces.IHelloWord"/>        <property name="registryPort" value="8088"/>     </bean></beans>

 

 

客户端接口类直接使用服务端的接口类直接粘贴过去。

客户端的运行类:

import com.interfaces.IHelloWord;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;/** * Created by lunhui.wei on 2014/11/7. */public class Run {    public static void main(String args[]){        ApplicationContext applicationContext=new ClassPathXmlApplicationContext("spring-config.xml");        IHelloWord helloWord= (IHelloWord) applicationContext.getBean("helloWorld");        System.out.println(helloWord.helloWorld());        System.out.println(helloWord.sayHelloToSomeBody("zhangsan"));    }}

客户端Spring 的配置:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="helloWorld" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">        <property name="serviceUrl" value="rmi://10.61.5.14:8088/hello"/>        <property name="serviceInterface" value="com.interfaces.IHelloWord"/>    </bean></beans>
