netty 系统空闲一段后,客户端与服务端的链接会自动断开如何处理

大伙有没有出现过这样的问题。用netty做集群服务器,包括客户端(clientBootstrap)和服务端(serverBootstrap),系统空闲3个多小时候,客户端与服务端的连接会自动断开(“远程主机强迫关闭了一个现有的连接”),系统重新后连接报异常:

java.lang.IllegalArgumentException: promise already done: DefaultChannelPromise@2038329b(failure(java.util.concurrent.CancellationException)

最后:

请问这个问题如何解决,我有做心跳处理,客户端每个几秒会请求服务端,这样都还会自动断开连接,好郁闷....

netty里面有一个自带的心跳handler,加上就行了

可以两边都加上option选项。ChannelOption.SO_KEEPALIVE 设置成true就可以。。。

服务端在运行若干小时以后就会卡死,不管客户端再怎么请求也收不到任何返回。主要是出现在业务逻辑线程池里: 我先放出线程堆栈: Full thread dump Java HotSpot(TM) 64-Bit Server VM (25.121-b13 mixed mode): "Attach Listener" #82 daemon prio=9 os_prio=0 tid=0x00007fe4e4001000 nid=0x5f1 waiting on condition [0x0000000000000000] java.lang.Thread.State: RUNNABLE "nioEventLoopGroup-4-32" #74 prio=10 os_prio=0 tid=0x00007fe46403c800 nid=0x6e28 runnable [0x00007fe45814d000] java.lang.Thread.State: RUNNABLE at sun.nio.ch.EPollArrayWrapper.epollWait(Native Method) at sun.nio.ch.EPollArrayWrapper.poll(EPollArrayWrapper.java:269) at sun.nio.ch.EPollSelectorImpl.doSelect(EPollSelectorImpl.java:93) at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:86) -

netty客户端与服务端连接后的通信
最近做的项目学习netty,时间紧来不及学,希望请教大家一些问题, 1.netty的客户端与服务端建立长连接后,客户端如何与服务端通信?要随心所欲发送自定义的消息? 2.netty的自定义编码器,解码器,希望也能得到帮助, 3.第一个问题为主要问题。 数据包结构: 包头:2字节 0ddd 0fff。 消息体:全部为文本(ASCII码),汉字是GB2312编码。 包尾:2字节 0xxx 0aaa。 最后,先感谢每一位浏览解答的朋友,我会多多赠送C币给那些乐于帮助的人。 补充一些: 我是客户端,需要与服务端长连接;接通后需要发送登陆消息数据包; 每30秒发送一条链路数据 这些我熬夜两天,时间太紧张,希望大家不吝指教。

Netty作为服务端,如何在读客户端数据时,知晓上一次写入的数据

netty为啥主动关闭客户端链接,求大牛指点
netty服务器启动后,客户端1600多个设备会主动连接上。 查看前几天的日志发现,时不时会有断开连接 关闭连接日志打印出来,也就是会调用netty的channelInactive 和 handlerRemoved 方法 ![图片说明](https://img-ask.csdn.net/upload/201711/02/1509593962_815809.png)![图片说明](https://img-ask.csdn.net/upload/201711/02/1509594004_151738.png) 当然也不排除是客户端主动断开的行为,但是直到昨天服务器直接挂掉了。 出现很奇怪的现象,当所有的设备连接上去的时候,过了几分钟就主动把客户端的连接T掉。![图片说明](https://img-ask.csdn.net/upload/201711/02/1509594204_993757.png)![图片说明](https://img-ask.csdn.net/upload/201711/02/1509596199_498810.png)![图片说明](https://img-ask.csdn.net/upload/201711/02/1509596465_671319.png) 在网上查了很多调优方案,但还是解决不了这个问题。服务器用的是阿里云Linux 64位,配置是双核 8G内存 5M带宽。现在就差没把服务器的配置提升了。客户端连接的时候我也监控过CPU和内存的使用都是够的,应该不会1600个socket连接承受不了吧。 已经找这个问题找了一天一夜了,不知道是哪里出了问题。求大神指导思路

netty-socket-io瞬间连接量太大
基于netty的socket-io的方式做一个客户端和服务端实时通讯的功能,当我们的系统重新部署之后,原先保持的连接肯定都断开-->重新连接服务端,那么服务端肯定有收到大量的连接请求,服务端又刚刚启动;所以有以下两个问题: 1.socket-io 基于普通的服务器最多能连接多少? 2.socket-io针对服务部署后客户端瞬时大量重新连接应该怎么处理? 3.有神没有什么预热的方式,缓解系统的一部分压力,防止系统宕机崩溃? 希望各位能够帮忙。
Netty怎么给一个特定客户端发送消息?
最近在学习netty网络通信,想通过服务端给某一个客户端发消息,不知道怎么做,求指点,求demo,谢谢
netty客户端向远程服务端发送数据包
首先,感谢每一位来关注的IT前辈,真诚希望您提出宝贵的意见。 我需要的效果: 1.客户端与服务端长连接TCP通信; 2.客户端通过自定义解码器,解析服务端返回的数据包; 3.客户端在服务端返回连接结果后,发送登录请求数据包,需要对数据自定义编码器解析; 4.因为是长连接,服务不能断,还需要发送登陆请求,以及其他验证消息。很重要。 **数据包结构:** 1.固定包头2字节; 2.消息体,全部为文本(ASCII码),汉字是GB2312编码。 3.固定包尾2字节; 我目前代码: public class TCPClient { public void connect(int port,String host)throws Exception{ //网络事件处理线程组 EventLoopGroup group=new NioEventLoopGroup(); //配置客户端启动类 Bootstrap b=new Bootstrap(); b.group(group).channel(NioSocketChannel.class) .option(ChannelOption.TCP_NODELAY, true)//设置封包 使用一次 大数据的写操作,而不是多次小数据的写操作 .handler(new ChannelInitializer<SocketChannel>() { @Override protected void initChannel(SocketChannel ch) throws Exception { ch.pipeline().addLast("decoder",new DealMsg()); //设置自定义解码器 ch.pipeline().addLast("encoder",new MsgEncode()); //设置自定义编码器 ch.pipeline().addLast(new TCPClientHandler()); //设置客户端网络IO处理器 } }); //连接服务器 同步等待成功 ChannelFuture f = b.connect(new InetSocketAddress(host,port)); //同步等待客户端通道关闭 // f.channel().closeFuture().sync(); //不关闭会发生阻塞 Channel channel = f.sync().channel(); Scanner scanner = new Scanner(System.in); while(true){ System.out.println("请输入"); CarData carData = new CarData(); String line = scanner.nextLine(); carData.setBody(line); //发送请求 channel.writeAndFlush(carData); } //释放线程组资源 // group.shutdownGracefully(); } } public class TCPClientHandler extends ChannelHandlerAdapter { @Override public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception { System.out.println("通信异常!!"); cause.printStackTrace(); } @Override public void channelActive(ChannelHandlerContext ctx) throws Exception { System.out.println("链接服务端成功!"); } @Override public void channelInactive(ChannelHandlerContext ctx) throws Exception { System.out.println("退出链接!!"); } @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception { System.out.println("接受服务器数据:【 "+msg); } @Override public void channelReadComplete(ChannelHandlerContext ctx) throws Exception { ctx.channel().writeAndFlush("数据读取完成!"); } }
Netty服务端如何保持稳定的长连接
有一个项目用到了netty来搭建服务端,主要是接入大量的客户端(目前有500多个客户端的接入),与服务端进行来消息的传送。但是,项目运行到一定时间后(大概10来天左右),链路channel就处于一种inactive的状态,导致客户端与服务端无法正常接收发送消息。重启netty server 后,链路又正常连接,又过一端时间后,又出现了上诉的问题。有哪位有经验的大神,能说一下这是什么情况吗?

关于Netty4 的channelread的ByteBuf写回客户端信息的迷惑 。
关于Netty4 的channelread的ByteBuf写回客户端信息的迷惑 ``` @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception { ByteBuf buf = (ByteBuf) msg; ctx.writeAndFlush(buf); } ``` 为什么在ServerHanlder的channelread方法里,这样直接把客户端发来的消息写回客户端,客户端收不到消息 而: ``` @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception { ByteBuf buf = (ByteBuf) msg; byte[] reg = new byte[buf.readableBytes()]; buf.readBytes(reg); String body = new String(reg, "UTF-8"); ByteBuf respByteBuf = Unpooled.copiedBuffer(body.getBytes()); ctx.writeAndFlush(respByteBuf ); } ``` 这样转成字符串再转回来却能将客户端发来的消息写回去,客户端也能接收到。。小白很迷求解这样强制转换有什么不同吗,跪谢大佬!
netty 服务器周期性的进步不去,服务端没有响应
我用netty4写了个服务器(客户端是Android),服务端有两个的handler,一个是登录注册用的,另一个是处理其他请求的,因为当时做也没什么经验,所以把业务逻辑都写在了handler里,但是部署到服务器后,每隔一段时间客户端访问服务端就没响应,查看进程仍在,但就是不能用,重启之后又能用了,打印日志都是些java.io.IOException: Connection reset by peer,请问问题出在了哪里?应该向哪方面排查?

Python十大装B语法
Python 是一种代表简单思想的语言,其语法相对简单,很容易上手。不过,如果就此小视 Python 语法的精妙和深邃,那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点,并附上详细的实例代码。如能在实战中融会贯通、灵活使用,必将使代码更为精炼、高效,同时也会极大提升代码B格,使之看上去更老练,读起来更优雅。 1. for - else 什么?不是 if 和 else 才
数据库优化 - SQL优化
前面一篇文章从实例的角度进行数据库优化,通过配置一些参数让数据库性能达到最优。但是一些“不好”的SQL也会导致数据库查询变慢,影响业务流程。本文从SQL角度进行数据库优化,提升SQL运行效率。 判断问题SQL 判断SQL是否有问题时可以通过两个表象进行判断: 系统级别表象 CPU消耗严重 IO等待严重 页面响应时间过长

通俗易懂地给女朋友讲:线程池的内部原理
餐厅的约会 餐盘在灯光的照耀下格外晶莹洁白,女朋友拿起红酒杯轻轻地抿了一小口,对我说:“经常听你说线程池,到底线程池到底是个什么原理?”我楞了一下,心里想女朋友今天是怎么了,怎么突然问出这么专业的问题,但做为一个专业人士在女朋友面前也不能露怯啊,想了一下便说:“我先给你讲讲我前同事老王的故事吧!” 大龄程序员老王 老王是一个已经北漂十多年的程序员,岁数大了,加班加不动了,升迁也无望,于是拿着手里

“狗屁不通文章生成器”登顶GitHub热榜,分分钟写出万字形式主义大作
一、垃圾文字生成器介绍 最近在浏览GitHub的时候,发现了这样一个骨骼清奇的雷人项目,而且热度还特别高。 项目中文名:狗屁不通文章生成器 项目英文名:BullshitGenerator 根据作者的介绍,他是偶尔需要一些中文文字用于GUI开发时测试文本渲染,因此开发了这个废话生成器。但由于生成的废话实在是太过富于哲理,所以最近已经被小伙伴们给玩坏了。 他的文风可能是这样的: 你发现,
程序员:我终于知道post和get的区别
IT界知名的程序员曾说:对于那些月薪三万以下,自称IT工程师的码农们,其实我们从来没有把他们归为我们IT工程师的队伍。他们虽然总是以IT工程师自居,但只是他们一厢情愿罢了。 此话一出,不知激起了多少(码农)程序员的愤怒,却又无可奈何,于是码农问程序员。 码农:你知道get和post请求到底有什么区别? 程序员:你看这篇就知道了。 码农:你月薪三万了? 程序员:嗯。 码农:你是怎么做到的? 程序员:
