Server 端：springremotingrmiserver

package com.studytrails.tutorials.springremotingrmiserver;
 
public interface GreetingService {
 
String getGreeting(String name);
}

package com.studytrails.tutorials.springremotingrmiserver;

public interface GreetingService {

String getGreeting(String name);
}

package com.studytrails.tutorials.springremotingrmiserver;

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

public class StartRmiServer {

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("spring-config-server.xml");
System.out.println("Waiting for Request from Client ...");

}
}

spring-config-server.xml:

Client 端：springremotingrmiclient

package com.studytrails.tutorials.springremotingrmiserver;
//和server的一样
public interface GreetingService {

String getGreeting(String name);
}

package com.studytrails.tutorials.springremotingrmiclient;

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

import com.studytrails.tutorials.springremotingrmiserver.GreetingService;

public class TestSpringRemotingRmi {

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("spring-config-client.xml");
GreetingService greetingService = (GreetingService)context.getBean("greetingService");
String greetingMessage = greetingService.getGreeting("Alpha");
System.out.println("The greeting message is : " + greetingMessage);
}
}

spring-config-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" xmlns:aop="http://www.springframework.org/schema/aop"

<bean id="greetingService" class="org.springframework.remoting.rmi.RmiProxyFactoryBean">
<property name="serviceUrl" value="rmi://localhost:1099/greetingService"/>
<property name="serviceInterface" value="com.studytrails.tutorials.springremotingrmiserver.GreetingService"/>
</bean>

</beans>

先启动Server, 后运行Client, 输出：
