springboot配置WebSocket的demo

好的，以下是一个简单的Springboot配置WebSocket的DEMO:

1. 配置依赖

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

2. 配置Endpoint

import org.springframework.stereotype.Component;
import org.springframework.web.socket.server.standard.SpringConfigurator;

import javax.websocket.*;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint(value = "/websocket", configurator = SpringConfigurator.class)
@Component
public class WebSocketServer {

    //连接建立成功调用
    @OnOpen
    public void onOpen(Session session) {
        System.out.println("WebSocket连接建立成功！");
    }

    //连接关闭调用
    @OnClose
    public void onClose() {
        System.out.println("WebSocket连接关闭！");
    }

    //接收到客户端消息时调用
    @OnMessage
    public void onMessage(String message, Session session) {
        System.out.println("接收到来自客户端的消息：" + message);
        sendMessage("已经接收到您发送的消息：" + message, session);
    }

    //发生错误时调用
    @OnError
    public void onError(Session session, Throwable error) {
        System.out.println("WebSocket发生错误：" + error.getMessage());
    }

    //发送消息
    public void sendMessage(String message, Session session) {
        try {
            session.getBasicRemote().sendText(message);
        } catch (Exception e) {
            System.out.println("发送消息出错：" + e.getMessage());
        }
    }
}

3. 配置WebSocket配置类

import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;

@Configuration
public class WebSocketConfig {
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }
}

4. 测试

//客户端代码
var ws = new WebSocket("ws://localhost:8080/websocket");

ws.onopen=function(event){
    console.log("WebSocket连接建立成功！");
    ws.send("Hello WebSocket！");
}

ws.onmessage=function(event){
    console.log("接收到服务端的消息："+event.data);
}

ws.onclose=function(event){
    console.log("WebSocket连接关闭！");
}

这是一个简单的WebSocket Demo，您可以根据自己的需求进行修改。希望能帮到您！如果您有任何问题，欢迎继续提问！
