我已经做了一段时间的网络编程,并且最近将我的一个项目转换为netty。由于与我的原始程序不同,客户端会在关闭前冻结约3-5秒,足以让我每次都终止它,因为我不想等待它,这让我很烦恼。 。这对于netty来说是正常的吗?难道我做错了什么?
主要方法:
public static void main(String[] args) throws Exception {
final SslContext sslCtx = SslContext.newClientContext(InsecureTrustManagerFactory.INSTANCE);
EventLoopGroup group = new NioEventLoopGroup();
try {
Bootstrap b = new Bootstrap();
b.group(group)
.channel(NioSocketChannel.class)
.handler(new NetworkInitializer(sslCtx));
// Start the connection attempt.
ch = b.connect(HOST, PORT).sync().channel();
//sends the clients name to the server
askname();
//loop just does some simple gl stuff and gameplay updating, posted below
while(running){loop();
if (Display.isCloseRequested()){
running = false;
if (lastWriteFuture != null) {
lastWriteFuture.sync();
} //tells the server to shut down
write("9");
ch.closeFuture().sync();
group.shutdownGracefully();
System.out.println("herro der");
break;
}
}
} finally {
group.shutdownGracefully();
// The connection is closed automatically on shutdown.
}
}
循环类:
private static void loop() {
GL11.glClear(GL11.GL_COLOR_BUFFER_BIT);
//main update method for my game. does calculations and stuff. I can post it if neccisary but its kinda big.
SpaceState.update();
Display.update();
Display.sync(60);
}
答案 0 :(得分:1)
group.shutdownGracefully();
会等待大约3秒钟,直到所有挂起的任务在终止之前完全执行。您可以指定不同的超时值,但是值太小会有获得RejectedExecutionException
的风险。如果您确定您的应用程序没有事件循环组的业务,您可以指定一个非常小的值来立即终止它。
