1. 在Eclipse里面创建一个server 端的project。然后，创建一个接口，这个接口是你要向client端开放的方法定义。它叫做：UserManagerInterface，而且必须继承Remote接口。
1 package dataserver.rmi.stub;
2
3 import java.rmi.Remote;
4 import java.rmi.RemoteException;
5
6 import dataserver.rmi.bean.Account;
7
8 public interface UserManagerInterface extends Remote{
9 public String getUserName() throws RemoteException;
10 public Account getAdminAccount() throws RemoteException;
11 }
2. 为了证明RMI中，“面向对象”或者是“无缝传递JAVA Object”是何等简单，我们需要定义一个Account类，该类是一个Bean，必须实现implements Serializable序列化接口。这是一个可以在client和server传输的可序列化对象。
package dataserver.rmi.bean;
import java.io.Serializable;
public class Account implements Serializable,Cloneable{
/**
*
*/
private static final long serialVersionUID = -1858518369668584532L;
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
3. 此时，需要实现你已经开放的接口：
package dataserver.rmi;
import java.rmi.RemoteException;
import dataserver.rmi.bean.Account;
import dataserver.rmi.stub.UserManagerInterface;
public class UserManagerImpl implements UserManagerInterface {
public UserManagerImpl() throws RemoteException {
//super();
// TODO Auto-generated constructor stub
//UnicastRemoteObject.exportObject(this);
}
/**
*
*/
private static final long serialVersionUID = -3111492742628447261L;
public String getUserName() throws RemoteException {
// TODO Auto-generated method stub
return "Tommy Lee";
}
public Account getAdminAccount() throws RemoteException {
// TODO Auto-generated method stub
Account account=new Account();
account.setUsername("admin");
account.setPassword("admin");
return account;
}
}
4. 定义一个主程序入口，注册你已经实现的RMI接口，包括开放端口等。其实很简单：
把我们的接口名称，命名为“userManager”,方便client进行调用
1 package dataserver.entry;
2
3 import java.rmi.AlreadyBoundException;
4 import java.rmi.RemoteException;
5 import java.rmi.registry.LocateRegistry;
6 import java.rmi.registry.Registry;
7 import java.rmi.server.UnicastRemoteObject;
8
9 import dataserver.rmi.UserManagerImpl;
10 import dataserver.rmi.stub.UserManagerInterface;
11
12 public class Entry {
13
14 public static void main(String []args) throws AlreadyBoundException, RemoteException{
15
16
17 UserManagerImpl userManager=new UserManagerImpl();
18 UserManagerInterface userManagerI=(UserManagerInterface)UnicastRemoteObject.exportObject(userManager,0);
19 // Bind the remote object‘s stub in the registry
20 Registry registry = LocateRegistry.createRegistry(2001);
21 registry.rebind("userManager", userManagerI);
22 System.out.println("server is ready");
23 }
24 }
5. Server端的代码已经全部写完，但是还要把bean类（Account）和接口类（UserMangerInterface）打包成jar，以便可以在下面导入进client端的项目中。
项目--》右键--》导出--》jar--》选择bean和interface--》命名为RmiServerInterface.jar--》finish
6. 开始创建client端的程序。新建一个project。创建完成后，把刚才jar包导入进client的项目中。
7. 导入我们的接口jar以后，可以开始编写一个client端的主程序，并调用server端的方法。
1 package weiblog.rmi;
2 import java.rmi.NotBoundException;
3 import java.rmi.RemoteException;
4 import java.rmi.registry.LocateRegistry;
5 import java.rmi.registry.Registry;
6
7 import dataserver.rmi.stub.UserManagerInterface;
8
9 public class Entry2 {
10
11 public static void main(String []args){
12
13 try {
14 Registry registry = LocateRegistry.getRegistry("localhost",2001);
15 UserManagerInterface userManager = (UserManagerInterface) registry.lookup("userManager");
16 System.out.println(""+userManager.getAdminAccount().getUsername()
17 +userManager.getAdminAccount().getPassword());
18 } catch (RemoteException e) {
19 // TODO Auto-generated catch block
20 e.printStackTrace();
21 } catch (NotBoundException e) {
22 // TODO Auto-generated catch block
23 e.printStackTrace();
24 }
25
26 }
27 }
8. 启动server端的主程序，然后启动client端的主程序。
server控制台打印：server is ready
client控制台打印：adminadmin
