Spring Boot整合WebSocket实现实时通信，前端实时通信，前后端实时通信

以下是一个使用Spring Boot整合WebSocket的简单示例，实现了前后端实时通信的功能。

后端代码（Spring Boot）:




import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.config.annotation.*;
 
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }
 
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/ws").withSockJS();
    }
}
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
 
@Controller
public class HomeController {
    @GetMapping("/")
    @ResponseBody
    public String home() {
        return "Welcome to WebSocket Chat!";
    }
}
 
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Controller;
 
@Controller
public class WebSocketController {
    @MessageMapping("/chat.sendMessage")
    @SendTo("/topic/public")
    public ChatMessage sendMessage(ChatMessage message) {
        return message;
    }
}
 
class ChatMessage {
    private String content;
    // getters and setters
}

前端代码（HTML + JavaScript）:




<!DOCTYPE html>
<html>
<head>
    <title>WebSocket Chat</title>
    <script src="https://cdn.jsdelivr.net/npm/sockjs-client@1.7.0/dist/sockjs.min.js"></script>

</head>
<body>
    <div>
        <input type="text" id="name" placeholder="Your Name" />
        <button id="connect">Connect</button>
        <button id="disconnect">Disconnect</button>
        <input type="text" id="message" placeholder="Message" />
        <button id="send">Send Message</button>
        <div id="conversationDiv">
            <label for="conversation">Conversation:</label>
            <textarea id="conversation" rows="4" cols="50"></textarea>
        </div>
    </div>
    <script>
        var stompClient = null;
        $('#con
