Spring利用代理，完成RMI服务端和客户端的开发，可以使任意POJO的方法进行暴露

服务接口：

package ch16.SimpleRMI;

public interface HelloWorld {
public String getMessage();
}

服务实现：

package ch16.SimpleRMI;

public class HelloWorldImpl implements HelloWorld {

    public String getMessage() {

        return "hello world";
    }

}

服务端配置文件：applicationContext.xml

<? 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-2.0.xsd" >
< bean id ="helloWorldService" class ="org.springframework.remoting.rmi.RmiServiceExporter" >
   < property name ="serviceName" >
     < value > HelloWorld </ value >
   </ property >
   < property name ="service" >
     < bean class ="ch16.SimpleRMI.HelloWorldImpl" />
   </ property >
   < property name ="serviceInterface" >
     < value > ch16.SimpleRMI.HelloWorld </ value >
   </ property >
   < property name ="registryPort" >
     < value > 9000 </ value >
   </ property >
   < property name ="servicePort" >
     < value > 9001 </ value >
   </ property >

</ bean >
</ beans >

客户端配置文件：applicationContext-client.xml

<? 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-2.0.xsd" >
< bean id ="helloworldService" class ="org.springframework.remoting.rmi.RmiProxyFactoryBean" >
< property name ="serviceUrl" >
    < value > rmi://localhost:9000/HelloWorld </ value >
</ property >
< property name ="serviceInterface" >
     < bean class ="ch16.SimpleRMI.HelloWorld" ></ bean >
   </ property >
</ bean >

< bean id ="helloworldClient" class ="ch16.SimpleRMI.HelloWorldClient" >
   < property name ="helloworldService" >
     < ref local ="helloworldService" />
   </ property >
</ bean >
</ beans >

服务端测试代码：

运行后并没有立即退出，因为远程服务是运行在后台的，一直等待客户端的链接

package ch16.SimpleRMI;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("ch16/SimpleRMI/applicationContext.xml");
        System.out.println("host stated...");
    }

}

客户端：

package ch16.SimpleRMI;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class HelloWorldClient {

    private HelloWorld helloworldService;
    public HelloWorld getHelloworldService() {
        return helloworldService;
    }
    public void setHelloworldService(HelloWorld helloworldService) {
        this.helloworldService = helloworldService;
    }
    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("ch6/SimpleRMI/applicationContext-client.xml");
        HelloWorldClient helloWorldClient=(HelloWorldClient)context.getBean("helloworldClient");
        helloWorldClient.run();
    }
    public void run(){
        System.out.println(helloworldService.getMessage());
    }

}

运行后，可以看到后台打印出了，服务端输出的Hello World

---------------------------------------下面注释为qlp3643_1加-----------------------------------------------------

其中需要特别注别的是：

<property name="registryPort">
    <value>9000</value>
  </property>
  <property name="servicePort">
    <value>9001</value>
  </property>
注册端口：registryPort   注册端口是RMI注册远程服务的端口。
