我需要让客户端能够建立许多连接。我使用 Netty 4.0。不幸的是,所有现有示例都没有显示如何创建大量连接。
public class TelnetClient {
private Bootstrap b;
public TelnetClient() {
b = new Bootstrap();
}
public void connect(String host, int port) throws Exception {
try {
b.group(new NioEventLoopGroup()).channel(NioSocketChannel.class).remoteAddress(host, port).handler(new TelnetClientInitializer());
Channel ch = b.connect().sync().channel();
ChannelFuture lastWriteFuture = null;
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
for (;;) {
String line = in.readLine();
if (line == null) break;
lastWriteFuture = ch.write(line + "\r\n");
if (line.toLowerCase().equals("bye")) {
ch.closeFuture().sync();
break;
}
}
if (lastWriteFuture != null) lastWriteFuture.sync();
} finally {
b.shutdown();
}
}
public static void main(String[] args) throws Exception {
TelnetClient tc = new TelnetClient();
tc.connect("127.0.0.1", 1048);
tc.connect("192.168.1.123", 1050);
//...
}
}
这是正确的决定吗?还是会更好?
