Chatty Server with Netty

Question

我用netty寫了一個簡單的聊天服務器，朋友，我一直在用telnet進行測試。當我們倆都連接時，它說組的大小是1.每當寫入用戶列表時，它只寫入發送該消息的人。我怎樣才能解決這個問題？

import org.jboss.netty.channel.SimpleChannelHandler; 
import org.jboss.netty.channel.Channel; 
import org.jboss.netty.channel.ChannelHandlerContext; 
import org.jboss.netty.channel.ChannelStateEvent; 
import org.jboss.netty.channel.MessageEvent; 
import org.jboss.netty.channel.group.ChannelGroup; 
import org.jboss.netty.channel.group.DefaultChannelGroup; 

public class ServerChannelHandler extends SimpleChannelHandler { 

    private ChannelGroup users = new DefaultChannelGroup(); 

    @Override 
    public void messageReceived(ChannelHandlerContext ctx, MessageEvent e) throws Exception { 
    users.write(e.getMessage()); 
    } 

    @Override 
    public void channelOpen(ChannelHandlerContext ctx, ChannelStateEvent e) throws Exception { 
    users.add(e.getChannel()); 
    System.out.println("Opened. "); 
    System.out.println(users.size()); 
    } 

    @Override 
    public void channelDisconnected(ChannelHandlerContext ctx, ChannelStateEvent e) throws Exception { 
    users.remove(e.getChannel()); 
    } 


}

您必須共享所有創建的ChannelPipeline實例的處理程序的相同實例。或宣佈ChannelGroup爲靜態最終
