RMI 채팅프로그램(Swing)

Class Server

public class ChatServer {
    private static Logger LOGGER = LogManager.getLogger(ChatServer.class);
    
    public ChatServer() {
        try {
            initRmi();
        } catch (Exception e) {
            LOGGER.error(e.getMessage(), e);
        }
    }
 
    private void initRmi() throws Exception {
        LOGGER.debug("+++ initRmi");
        ChatImpl chatImpl = new ChatImpl();
                
        // 내부에 rmi registry를 생성한다.
        Registry registry = LocateRegistry.createRegistry(1099);
        registry.bind("chat", chatImpl);
        
        LOGGER.debug("--- initRmi");
    }
    
    public static void main(String[] args) {
        new ChatServer();
    }
}

import java.rmi.Remote;
import java.rmi.RemoteException;
 
import com.barunsw.imj.day12.chat.client.ChatRecvInterface;
 
public interface ChatInterface extends Remote {
    public int login(String userId, ChatRecvInterface chatRecvIf) throws RemoteException;
    public int logout(String userId) throws RemoteException;
    public int message(String message) throws RemoteException;
}
 

RMI을 사용하기 위해서는 interface에서 Remote를 상속 받아야함

 

throse RemoteExeption을 안쓰면 java.lang.IllegalArgumentException 발생
