java版本使用springboot vue websocket webrtc实现视频通话

以下是一个简化的示例，展示了如何在Spring Boot后端中使用WebSocket和WebRTC实现视频通话的基本框架：

后端（Spring Boot）:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/video-call");
        config.setApplicationDestinationPrefixes("/app");
    }
 
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/video-call").withSockJS();
    }
}
 
@Controller
public class VideoCallController {
 
    @MessageMapping("/video-call/offer")
    @SendTo("/video-call/broadcast")
    public VideoCallMessage broadcastOffer(VideoCallMessage videoCallMessage) {
        return videoCallMessage;
    }
 
    @MessageMapping("/video-call/answer")
    @SendTo("/video-call/broadcast")
    public VideoCallMessage broadcastAnswer(VideoCallMessage videoCallMessage) {
        return videoCallMessage;
    }
 
    @MessageMapping("/video-call/candidate")
    @SendTo("/video-call/broadcast")
    public VideoCallMessage broadcastCandidate(VideoCallMessage videoCallMessage) {
        return videoCallMessage;
    }
}
 
public class VideoCallMessage {
    private String from;
    private String to;
    private String type;
    private Object content;
    // Getters and Setters
}

前端（Vue.js）:

<template>
  <div>
    <button @click="startVideoCall">开始视频通话</button>
    <video ref="localVideo" autoplay></video>
    <video ref="remoteVideo" autoplay></video>
  </div>
</template>
 
<script>
export default {
  methods: {
    startVideoCall() {
      // 建立WebSocket连接并处理信令
      const socket = new WebSocket('ws://localhost:8080/video-call');
      socket.onopen = () => { /* 发送OFFER信令 */ };
      socket.onmessage = (message) => {
        const data = JSON.parse(message.data);
        switch (data.type) {
          case 'offer':
            // 处理OFFER
            break;
          case 'answer':
            // 处理ANSWER
            break;
          case 'candidate':
            // 处理CANDIDATE
            break;
        }
      };
      
      // 创建RTCPeerConnection
      const peerConnection = new RTCPeerConnection({...});
      
      // 将视频源绑定到video元素
      navigator.mediaDevices.getUserMedia({ video: true, audio: true })
        .then(stream => {
          thi
