客户端每5秒发送一次心跳给服务端，服务端记录最后一次心跳时间，通过定时任务每10秒检测一下，如果当前时间与最后一次收到的心跳时间之差超过某个阈值，断开与客户端的连接。基于之前的例子（netty5心跳与业务消息分发实例），我们修改下服务端的心跳handler（HeartBeatServerHandler）：
package com.wlf.netty.nettyserver.handler; import com.wlf.netty.nettyapi.constant.MessageType; import com.wlf.netty.nettyapi.javabean.NettyMessage; import io.netty.channel.ChannelHandlerAdapter; import io.netty.channel.ChannelHandlerContext; import io.netty.util.concurrent.ScheduledFuture; import lombok.extern.slf4j.Slf4j; import java.util.concurrent.TimeUnit; @Slf4j public class HeartBeatServerHandler extends ChannelHandlerAdapter { private volatile boolean isReceiveHeart = false; private volatile int interval = 10000; private volatile ScheduledFuture<?> heartBeatLost; // 心跳消息接收时间点 private final ThreadLocal<Long> heartBeatTime = new ThreadLocal<>(); @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception { NettyMessage nettyMessage = (NettyMessage) msg; // 接收到心跳请求，打印心跳消息 if (nettyMessage.getHeader() != null && nettyMessage.getHeader().getType() == MessageType.HEART_TYPE.getType()) { // 收到消息 isReceiveHeart = true; // 获取最后一次心跳收到的时间 heartBeatTime.set(System.currentTimeMillis()); log.info("[server] Receive client heart beat message : ----> {}", nettyMessage); } else { ctx.fireChannelRead(msg); } } @Override public void channelActive(ChannelHandlerContext ctx) throws Exception { // 通道联通后开始定时监听连接接入，超时则断连 heartBeatLost = ctx.executor().scheduleAtFixedRate(new Runnable() { @Override public void run() { log.info("isReceiveHeart : {}", isReceiveHeart); if (isReceiveHeart) { long currentTime = System.currentTimeMillis(); long lastHeartBeatTime = heartBeatTime.get() == null ? currentTime : heartBeatTime.get(); long timeOut = currentTime - lastHeartBeatTime; log.info("[server] heart timeOut is : {} ms", timeOut); if (timeOut > interval) { log.error("[server] heart beat time out."); // 关闭监听任务，断开通道 heartBeatLost.cancel(true); ctx.close(); } } } }, 0, interval, TimeUnit.MILLISECONDS); } /** * 在处理过程中引发异常时被调用 * * @param ctx * @param cause * @throws Exception */ @Override public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception { log.error("[server] heart response error: {}", cause.getMessage()); if (heartBeatLost != null) { heartBeatLost.cancel(true); heartBeatLost = null; } ctx.fireExceptionCaught(cause); } }
当通道激活时我们起一个定时任务检测，若有心跳消息进来，我们开始计算心跳是否超时，当客户端把文件发完后，心跳也不跳了，服务端检测到超时断连，客户端输出结果：
