首先,我承认我是新手,我可能只是忘记在某个地方为正确的变量设置一个选项,但是我的谷歌搜索失败了,我不知道该怎么做,所以我希望得到一些帮助。
我基于 SecureChat 示例,它可以位于此处:http ://netty.io/docs/unstable/xref/org/jboss/netty/example/securechat/package-summary.html
而我所做的不同之处仅在于 SecureChatServerHandler。更准确地说,在 messageRecieved 块中:
@Override
public void messageReceived(ChannelHandlerContext ctx, MessageEvent e) throws Exception {
// Convert the message to a string
String request = (String) e.getMessage();
System.out.println("Message recieved: " + request);
if (request.equalsIgnoreCase("clients")) {
channels.write("We currently have: " + channels.size() + " clients");
} else if (request.toLowerCase().equals("koko"))
for (Channel c : channels) {
if (c == e.getChannel())
c.write("HELLO WORLD");
}
else {
// Then send it to all channels, but the current one.
for (Channel c : channels)
if (c != e.getChannel())
c.write("[" + e.getChannel().getRemoteAddress() + "] " + request + "\n");
else
c.write("[you] " + request + "\n");
}
if (request.equalsIgnoreCase("bye"))
e.getChannel().close();
}
如果我发送一条正在广播的正常消息,则一切正常。但是如果我发送一个命令,比如clients或koko,我没有得到任何响应,直到我再次按 enter 并发送一条空消息。首先,我得到回复。

我不明白,也不想要的是 - 按下输入按钮两次 - 事情。这似乎非常不合逻辑,而且令人恼火。Telnet 示例没有这些问题。
感谢您的时间。
问候,奥尔德里安。
