在springboot中使用websocket

在Spring Boot中使用WebSocket需要进行以下步骤：

1. 引入WebSocket依赖

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

2. 创建WebSocket处理器

public class MyWebSocketHandler extends TextWebSocketHandler {
    @Override
    protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
        // 处理收到的消息
        String payload = message.getPayload();
        // 发送消息给所有连接的客户端
        session.getWebSocketHandler().broadcast(new TextMessage("Hello, " + payload + "!"));
    }
}

3. 配置WebSocket

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(myWebSocketHandler(), "/my-websocket").setAllowedOrigins("*");
    }

    @Bean
    public MyWebSocketHandler myWebSocketHandler() {
        return new MyWebSocketHandler();
    }
}

4. 编写前端代码

<script>
    var socket = new WebSocket("ws://localhost:8080/my-websocket");
    socket.onmessage = function(event) {
        // 处理收到的消息
        console.log(event.data);
    }
    socket.send("World");
</script>

以上就是在Spring Boot中使用WebSocket的步骤，你可以根据自己的实际情况进行调整。
