rmi、简单应用

RMI简单应用：

我决定秉承一贯直接、爽快作风，直接代码分析：

服务器端代码：

package rmi.server.i;

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

/**
 *  @ version 创建时间：2014-3-24 上午11:25:58
 *
 *  @ author  leicl   
 *
 *  类说明：
 *  服务器端方法，供客户端访问，需要注册
 *
 */
public interface ServerFunctionI extends Remote{

 
 public int add(int i, int j) throws RemoteException;
 
 public int div(int i, int j) throws RemoteException;
}
 package rmi.server.imp;

import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;

import rmi.server.i.ServerFunctionI;

/**
 *  @ version 创建时间：2014-3-24 上午11:28:16
 *
 *  @ author  leicl   
 *
 *  类说明：
 *
 */
public class ServerFunctionImp extends UnicastRemoteObject implements ServerFunctionI{

 public ServerFunctionImp() throws RemoteException {
  super();
 }

 private static final long serialVersionUID = -6669980253701448838L;

 public int add(int i, int j) throws RemoteException {
  // TODO Auto-generated method stub
  return i+j;
 }

 public int div(int i, int j) throws RemoteException {
  // TODO Auto-generated method stub
  return i-j;
 }

}
客户端调用：

package rmi.client;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.ServerSocket;
import java.net.Socket;
import java.rmi.AlreadyBoundException;
import java.rmi.Naming;
import java.rmi.NotBoundException;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.RMIClientSocketFactory;
import java.rmi.server.RMIServerSocketFactory;

import rmi.server.i.ServerFunctionI;
import rmi.server.imp.ServerFunctionImp;

/**
 * @ version 创建时间：2014-3-24 上午11:33:04
 *
 * @ author leicl
 *
 * 类说明：
 *
 */
public class Client1 {

 public static void main(String[] args) throws MalformedURLException,
   RemoteException, AlreadyBoundException, NotBoundException {
  ServerFunctionI s = new ServerFunctionImp();

  Registry regist = LocateRegistry.createRegistry(2323,
    new RMIClientSocketFactory() {

     public Socket createSocket(String host, int port)
       throws IOException {
      Socket s = new Socket(host, port);
      return s;
     }
    }, new RMIServerSocketFactory() {

     public ServerSocket createServerSocket(int port)
       throws IOException {
      ServerSocket s = new ServerSocket(port);
      return s;
     }
    });
  regist.bind("server", s);
  String[] list = Naming.list("rmi://127.0.0.1:2323");
  for (int i = 0; i < list.length; i++) {
   System.out.println(list[i]);
  }
  ServerFunctionI ser = (ServerFunctionI) Naming
    .lookup("rmi://127.0.0.1:2323/server");
  int add = ser.add(1, 1);
  System.out.println(add);
 }

}
