spring-cloud-websocket-cluster-netty

介绍

基于spring-cloud与redis的websocket netty版集群解决方案

软件架构

本项目基于spring-cloud 与 redis 做出的websocket集群方案

需要第三方服务

  1. nacos
  2. redis
  3. netty

使用说明

  1. 所有服务都可以启动多个,保证了动态扩容
  2. network-message 为基础包,各个服务之间通信类在这个里面,包含了proto类等
  3. common 为基础包,包含了常用的枚举,比如服务类型、通用返回等数据
  4. gateway-server 为网关服务,重点为WebSocketGatewayFilter类,此可以保证了网关动态连接到ws服务,建议鉴权可以在此处完成,保证连接到websocket的都是有效连接
  5. netty-websocket-starter 是基础,让使用netty的websocket跟使用springboot的websocket一样简单
  6. ws-facade 需要通过其他服务直接给用户发送消息直接集成这个即可
  7. ws-transit 中转集成,需要接收websocket服务的消息,直接集成这个服务,然后利用EntranceService自己的业务即可
  8. ws-server websocket服务,与用户建立联系,接收发送消息,重点可看WebSocket类,onBinary 同步异步发送消息,给有状态,无状态服务发送消息都在这里
  9. open-server 是一个对外开放的服务,可以让其他不是该微服务架构体系下的也能给用户发送消息
  10. activity-server 服务是一个示例服,该服务可以接收websocket的消息,完成自己的业务处理,然后将消息返回给用户

项目优势

  1. 传统websocket集群服务服务端给客户端发送消息,需要采用MQ进行广播发送,每个websocket服务都要接收消息,然后解析发送,这种方案链路太长,同时严重浪费性能
  2. 本项目纯微服务架构,直接通过feign接口调用的方式,直接将消息发送到用户链接的socket服务上,不需要走第三方服务
  3. websocket服务接受同步与异步两种消息类型
  4. websocket服务支持有状态服务与无状态服务两种发消息
  5. 开放接口,非该服务架构体系下的项目也能给用户发送消息
  6. 需要使用到websocket收发消息的,可快速集成
  7. 多服务挤下线功能,支持多端设备同时在线,但同一设备只能链接一个socket,设备类型可以在DeviceEnum枚举类里面设置
  8. 查找用户发送消息,基本是在内存查找,效率杠杠的
  9. 使用最新springcloud2023 springboot3.2.0 java21,开启虚拟线程处理,访问速度更快了
  10. 待更新

应用场景

  1. 游戏
  2. IM
  3. 客服系统
  4. 以及其他需要及时通讯的项目
  5. 其他需要提高响应速度的项目,可以将http改用websocket
