16.Springboot集成Websocket最简单示例

Springboot集成Websocket

1.导入pom依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

2.编写Websocket配置类

@Slf4j
@Configuration
@EnableWebSocket
public class WebSocketConfig {
    @Bean
    public ServerEndpointExporter serverEndpoint(){
        return new ServerEndpointExporter();
    }

}

3.编写Controller类

import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

@Slf4j
@Component
@ServerEndpoint("/websocket")
public class WebSocketController {

    @OnOpen
    public void onOpen(Session session) {
        log.info("客户端：" + session.getId() + "连接成功");
    }

    @OnClose
    public void onClose(Session session) {
        log.info("客户端：" + session.getId() + "连接断开");

    }

    @OnMessage
    public String onMsg(String message, Session session) {
        log.info("从客户端：" + session.getId() + " 收到消息：" + message);
        return "返回消息：" + message;
    }
}
