public class OpenfireManager {
	
	private  XMPPConnection connection;
	public XMPPConnection getConnection() {
		return connection;
	}

	private String userName="admin";
	private String pwd="qq603665610";  
	
	private PacketListener listener;

	}
	
	public void addConnectionListener(ConnectionListener l)
	{
		connection.addConnectionListener(l);
	}
	
	private OpenfireManager(){
		
	}
	
	
	synchronized public Chat createChat(String to) {
        Chat chat = null;
        if (isConnected()) {

        System.out.println("openfire login");
		
	}

	synchronized public void disconnect()
	{
		if(connection!=null && connection.isConnected())
		{
			connection.removePacketListener(listener);
//			connection.sendPacket(new Presence(Presence.Type.unavailable));
			new Thread(){
				
				public void run()
				{
					try
					{
						connection.disconnect(new Presence(Presence.Type.unavailable));
					}
					catch(Exception e)
					{
						
					}
				}
				
				
			}.start();
			
		}
	}



}

 

实现消息发送：

try {
					if(OpenfireManager.getInstance().getConnection()==null){
						OpenfireManager.getInstance().init(UserAction.this, "admin", "qq603665610");
						OpenfireManager.getInstance().connect();
						
					}
					connection=OpenfireManager.getInstance().getConnection();
					if(!OpenfireManager.getInstance().isLogin()){
						OpenfireManager.getInstance().login();
					}
					Chat chat=createChat("client");
					String aa=connection.getUser();
					System.out.println(connection.getUser());
					OpenfireManager.getInstance().sendMessage(chat, "123456", "regCode");
