封装的IM启动类：

public class WebIMStarter {

    private WsServerStarter wsServerStarter;

    private ServerTioConfig serverTioConfig;

    public WebIMStarter(WsServerConfig wsServerConfig) throws IOException {
        wsServerStarter = new WsServerStarter(wsServerConfig,new WebSocketHandler());
        serverTioConfig = wsServerStarter.getServerTioConfig();
    }

    public WsServerStarter getWsServerStarter() {
        return wsServerStarter;
    }

    public ServerTioConfig getServerTioConfig() {
        return serverTioConfig;
    }

    public void start() throws IOException {
        wsServerStarter.start();
    }
}

自定义了一个监听，已经绑定到ServerTioConfig中

@Configuration
@EnableConfigurationProperties(WebImProperties.class)
public class WebImConfig {

    @Autowired
    private WebImProperties properties;


    @Bean
    public WebIMStarter webIMStarter() throws IOException {
        WsServerConfig wsServerConfig = new WsServerConfig(Integer.parseInt(properties.getTioServerPort()),false);
        wsServerConfig.setBindIp(properties.getTioServerIp());
        WebIMStarter webIMStarter = new WebIMStarter(wsServerConfig);
        ServerTioConfig serverTioConfig = webIMStarter.getServerTioConfig();
        serverTioConfig.setServerAioListener(new WebImServerAioListener());
        serverTioConfig.setHeartbeatTimeout(properties.getTioTimeout());
        webIMStarter.start();
        return webIMStarter;
    }
}

监听类如下：

public class WebImServerAioListener extends WsServerAioListener {

    private static final Logger logger = LoggerFactory.getLogger(WebImServerAioListener.class);

    @Override
    public boolean onHeartbeatTimeout(ChannelContext channelContext, Long interval, int heartbeatTimeoutCount) {
        logger.info("心跳超时：{}", channelContext);
        //用户统计
        WebImClients.removeUserChannelContext(channelContext.userid,channelContext.getId());
        WebImClients.setTotalChannelContextNum(Tio.getByGroup(channelContext.getTioConfig(),"tianxia").size());
        WebIMUtil.sendOnLineMsg(channelContext);
        return super.onHeartbeatTimeout(channelContext, interval, heartbeatTimeoutCount);
    }
}

但是有连接心跳超时的时候，没有回调我自定义监听的心跳超时方法。
debugger发现线程调用的是默认的
wsServerAioHandler = new WsServerAioHandler(wsServerConfig, wsMsgHandler);
截图如下：
