tio-websocket-spring-boot-starter

快速开始

  • 引入 jar 包
      <dependency>
            <groupId>org.t-io</groupId>
            <artifactId>tio-websocket-spring-boot-starter</artifactId>
			<!--此版本号跟着tio主版本号一致即可-->
            <version>3.3.2.v20190601-RELEASE</version>
        </dependency>
  • 添加注解
@SpringBootApplication
@EnableTioWebSocketServer
public class SamplesApplication {
    public static void main(String[] args) {
        SpringApplication.run(SamplesApplication.class,args);
    }
}
  • 修改配置文件
tio:
  websocket:
    server:
      port: 9876
      heartbeat-timeout: 60000
      #是否支持集群,集群开启需要redis
    cluster:
      enabled: false
    redis:
      ip: 192.168.1.225
      port: 6379
  • 编写消息处理类
public class MyWebSocketMsgHandler implements IWsMsgHandler {

    @Override
    public HttpResponse handshake(HttpRequest httpRequest, HttpResponse httpResponse, ChannelContext channelContext) throws Exception {
        return httpResponse;
    }

    @Override
    public void onAfterHandshaked(HttpRequest httpRequest, HttpResponse httpResponse, ChannelContext channelContext) throws Exception {
        System.out.println("握手成功");
    }

    @Override
    public Object onBytes(WsRequest wsRequest, byte[] bytes, ChannelContext channelContext) throws Exception {
        System.out.println("接收到bytes消息");
        return null;
    }

    @Override
    public Object onClose(WsRequest wsRequest, byte[] bytes, ChannelContext channelContext) throws Exception {
        return null;
    }

    @Override
    public Object onText(WsRequest wsRequest, String s, ChannelContext channelContext) throws Exception {
        System.out.println("接收到文本消息:"+s);
        return null;
    }
}

  • 编写简单客户端
    <script>
        var ws =new WebSocket("ws://localhost:9876");
        ws.onopen = function (event) {
            console.log("opened");
            ws.send("Hello Tio WebSocket");
        }
        ws.onmessage=function (p1) {
            console.log(p1.data);
        }
    </script>

  • 运行程序,打开浏览器,Console 打印
opened
服务器收到了消息:Hello Tio WebSocket

原生回调接口支持

通过包扫描,反射创建新实例,赋给 TioWebSocketServerBootstrap中的属性。客户端编写相应的类即可,如下:

//最主要的逻辑处理类,必须要写,否则 抛异常
public class MyWebSocketMsgHandler  implements IWsMsgHandler {}
//可不写
public class SpringBootAioListener extends WsServerAioListener {}
//可不写
public class SpringBootGroupListener implements GroupListener {}
//可不写
public class SpringBootIpStatListener implements IpStatListener {}

服务端主动推送

主动推送消息,核心在于获取 ServerGroupContext。

@RestController
@RequestMapping("/push")
public class PushController {

    @Autowired
    private TioWebSocketServerBootstrap bootstrap;

    @GetMapping("/msg")
    public void pushMessage(String msg){
        if (StrUtil.isEmpty(msg)){
            msg = "hello tio websocket spring boot starter";
        }
        Tio.sendToAll(bootstrap.getServerGroupContext(), WsResponse.fromText(msg,"utf-8"));
    }
}

SSL 支持

配置文件中增加如下配置

 # SSL 配置
    ssl:
      enabled: true
      key-store: key-store path
      password: password
      trust-store: trust-store path

集群支持

  # 集群配置 默认关闭
    cluster:
      enabled: false
      # 集群是通过redis的Pub/Sub实现,所以需要配置Redis
      redis:
        ip: 127.0.0.1
        port: 6379
      all: true
      group: true
      ip: true
      user: true

总结

tio-websocket-spring-boot-starter的宗旨和所有spring boot starter一致,通过配置实现快速开发。而又不会失去tio的代码灵活性。通过配置文件可以自由配置相应的功能,例如 SSL,集群等。注:本项目并未改变使用tio开发业务代码的方式。例如:Tio类的各种功能,同样适用。

注意

由于 bean 的加载顺序不同,可能在不同的功能类中注入tio-websocket-starter中的bean会有意想不到的问题。但是,基本很少,最常用的基本就是上文中的TioWebSocketServerBootstrap了,用它来获取ServerGroupContext,毕竟ServerGroupContext才是核心。

其他功能

具体参考 tio-websocket-server 项目。
