jdk1.5 下 rmi的编写

jdk1.5 自动生成stub 更加方便

接口Hello

package example.hello;

import java.rmi.Remote;
import java.rmi.RemoteException;

public interface Hello extends Remote {
    String sayHello() throws RemoteException;
}

服务端

package example.hello;

import java.rmi.registry.Registry;
import java.rmi.registry.LocateRegistry;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;

public class Server implements Hello {

    public Server() {}

    public String sayHello() {
	return "Hello, world!";
    }
    public static void main(String args[]) {

	try {
	    Server obj = new Server();
	    Hello stub = (Hello) UnicastRemoteObject.exportObject(obj, 0);
	    Registry registry = LocateRegistry.createRegistry(1078);
	    registry.bind("server", stub);
	    System.err.println("Server ready");
	} catch (Exception e) {
	    System.err.println("Server exception: " + e.toString());
	    e.printStackTrace();
	}
    }
}

客户端

package example.hello;

import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;

public class Client {

    private Client() {}

    public static void main(String[] args) {
	String host = (args.length < 1) ? null : args[0];
	try {
         //可以用Naming.lookup("rmi://localhost:1078/server");
         //来替换下面代码
	    Registry registry = LocateRegistry.getRegistry(null,1078);
	    Hello stub = (Hello) registry.lookup("server");
	    String response = stub.sayHello();
	    System.out.println("response: " + response);
	} catch (Exception e) {
	    System.err.println("Client exception: " + e.toString());
	    e.printStackTrace();
	}
    }
}
