Openfire 使用RMI远程调用同步好友列表

1. 定义接口：

public interface RmiRemoteIntface extends Remote{

    void deleteFriend(String user1, String user2) throws RemoteException;

    String addFriend(String user1, String user2) throws RemoteException;
}

2. 实现接口

public class RmiRemoteObj extends UnicastRemoteObject implements
        RmiRemoteIntface {

    protected RmiRemoteObj() throws RemoteException {
        super();
    }

    @Override
    public void deleteFriend(String user1, String user2) throws RemoteException {
//        IQ iq = new IQ();
//        iq.setType(IQ.Type.set);
//        for (ClientSession session : XMPPServer.getInstance().getRoutingTable().getClientsRoutes(true)) {
//            if (session.getAddress().getNode().equals(user1)) {
//                processDeleteMsg(iq, user2, session);
//            } else if (session.getAddress().getNode().equals(user2)) {
//                processDeleteMsg(iq, user1, session);
//            }
//        }
//        Element element = null;
    }

    public String addFriend(String user1, String user2) throws RemoteException{
//        IQ iq = new IQ();
//        iq.setType(IQ.Type.set);
//        for (ClientSession session : XMPPServer.getInstance().getRoutingTable().getClientsRoutes(true)) {
//            if (session.getAddress().getNode().equals(user1)) {
//                processAddMsg(iq, user2, session);
//            } else if (session.getAddress().getNode().equals(user2)) {
//                processAddMsg(iq, user1, session);
//            }

        System.out.println(user1+ " "+user2);
        return user1+" "+user2+ " hello world " ;
        }

3. 编写RmiServer

public class RmiServer extends Thread{
    public static int rmi = 0;
    public static RmiServer rmiServer;
    static{
        rmiServer = new RmiServer();
        rmiServer.setDaemon(false);
        rmiServer.start();
    }

    public static void main(String args[]){
        //创建并安装安全管理器
//        if(System.getSecurityManager() == null){
//            System.setSecurityManager(new RMISecurityManager());
//        }
        try{
            LocateRegistry.createRegistry(8057);
            //创建远程对象
            RmiRemoteIntface rro = new RmiRemoteObj();
            //将实例注册到专有的URL
            Naming.rebind("//127.0.0.1:8057/RmiRemoteObj", rro);

            System.out.println("RMI服务器正在运行...");
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    public void run(){
        try{
            LocateRegistry.createRegistry(8057);
            //创建远程对象
            RmiRemoteIntface rro = new RmiRemoteObj();
            //将实例注册到专有的URL
            Naming.rebind("//127.0.0.1:8057/RmiRemoteObj", rro);

            System.out.println("RMI服务器正在运行...");
        }catch(Exception e){
            e.printStackTrace();
        }
    }

4. 编写RmiClient

public class RmiClient {

    public static void main(String args[]){
        //创建并安装安全管理器
//        if(System.getSecurityManager()==null)
//        {
//           System.setSecurityManager(new RMISecurityManager());
//        }

        String host = "rmi://127.0.0.1:8057/RmiRemoteObj";
//        String host = "rmi://192.168.1.103:2099/RmiRemoteObj";
//        String host = "rmi://192.168.1.119:2099/RmiRemoteObj";
//        if(args.length > 0){
//            host = args[0];
//        }

        try{
            //根据制定的URL定位远程对象
            RmiRemoteIntface rri = (RmiRemoteIntface)Naming.lookup(host);
//            rri.addFriend("test01", "test02");
            System.out.println(rri.addFriend("aaaaaaa", "ccc"));
//            rri.deleteFriend("admin", "kocko");
            System.out.println("调用成功！");
        }catch(Exception e){
            e.printStackTrace();
        }

    }

5. 在Openfire启动时加载Rmi服务

在类org.jivesoftware.openfire.spi.ConnectionManagerImpl 的方法 startListeners(）startHTTPBindListeners后面加上RmiServer rmi = new RmiServer();

搞定！

RmiServer rmi = new RmiServer();
