spring rmi 简单应用

最近当涉及到spring rmi操作时,对于客户端提供接口给服务器端的情况还是第一次使用,今天晚上抽出一点时间做了一个小程序,希望能给spring rmi应用者,带来帮助,同时希望大家互相讨论.

1.程序分为客户端和服务端,分别用clientRmi,serverRmi来表示

1.1客户端三个类.

(1).IMessage(接口)

package client;

import java.util.List;

public interface IMessage {

	public void putMessage(String str);

	public List<String> getMessage();
}

 

(2).MessageImpl(上边接口的实现类)

package client;

import java.util.ArrayList;
import java.util.List;

public class MessageImpl implements IMessage {

	private static List<String> strings = new ArrayList<String>();

	@Override
	public List<String> getMessage() {
		synchronized (strings) {
			while (true) {
				if (strings.size() == 0) {
					try {
						strings.wait();
					} catch (InterruptedException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
				} else {
					return strings;
				}
			}
		}
	}

	@Override
	public void putMessage(String str) {
		synchronized (strings) {
			strings.add(str);
			strings.notifyAll();
		}
	}

}

 

(3).MainClient(包含Main方法)

package client;

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

public class MainClient {

	public static void main(String[] args) {
		ApplicationContext factory = new ClassPathXmlApplicationContext(
				"clientRmi.xml");
		final IMessage mess = (IMessage) factory.getBean("messageImpl");

		Runnable run = new Runnable() {
			@Override
			public void run() {
				while (true) {
					try {
						Thread.sleep(1000);
					} catch (InterruptedException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
					System.out.println(mess.getMessage().size());
				}
			}
		};

		Thread thread = new Thread(run);
		thread.start();
	}
}

 

2.2服务器端也有三个类

(1).IMessage(接口和上边的一样)

(2).ThreadTool(线程工具类)这个类通过rmi访问client端的messageImpl类并且传递值过去

package server;


public class ThreadTool implements Runnable {

	private IMessage message;

	public void setMessage(IMessage message) {
		this.message = message;
	}

	@Override
	public void run() {
		for (int i = 0; i < 100000; i++) {
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			message.putMessage("value" + i);
		}
	}

}

 

(3).MainServer(启动server端的类)

package server;

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

public class MainServer {

	public static void main(String[] args) {
		ApplicationContext factory = new ClassPathXmlApplicationContext(
				"serverRmi.xml");
		ThreadTool threadTool = (ThreadTool) factory.getBean("threadTool");
		threadTool.run();
	}
}

 首先启动client端,然后是server端,打开client端的控制台,server端将定时想client的List<String>数据结构中放入值.client的Console中便可以看到结果.
