Spring Boot整合STOMP实现实时通信

import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;
 
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
 
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/ws").withSockJS();
    }
 
    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/topic");
        registry.setApplicationDestinationPrefixes("/app");
    }
}

这段代码配置了Spring Boot中的WebSocket消息代理，使得客户端能够通过WebSocket连接到服务器，并使用STOMP协议来发送和接收消息。registerStompEndpoints方法注册了一个WebSocket端点/ws，并且指示使用SockJS来兼容不支持WebSocket的浏览器。configureMessageBroker方法配置了一个简单的消息代理用于转发消息，并设置了应用程序的目的地前缀为/app。这样，客户端可以通过/app发送消息，服务器通过/topic接收并转发消息。
