Spring 4 WebSocket远程代理配置

使用Spring 4 WebSocket实现远程代理配置可以帮助我们在分布式系统中实现实时通信的功能。WebSocket是一种在Web应用程序中提供双向通信的协议，可以通过它来实现浏览器与服务器之间的实时数据传输。通过远程代理配置，我们可以将WebSocket连接的处理逻辑从应用程序中分离出来，使其成为一个独立的服务。

java
@SpringBootApplication
@EnableWebSocket
public class WebSocketServer {
    public static void main(String[] args) {
        SpringApplication.run(WebSocketServer.class, args);
    }
    @Bean
    public WebSocketHandler myWebSocketHandler() {
        return new MyWebSocketHandler();
    }
    @Bean
    public SimpleUrlHandlerMapping myUrlHandlerMapping() {
        SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();
        mapping.setUrlMap(Collections.singletonMap("/websocket", myWebSocketHandler()));
        return mapping;
    }
}

java
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/topic");
        registry.setApplicationDestinationPrefixes("/app");
    }
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/websocket")
                .setAllowedOrigins("*")
                .withSockJS();
    }
}
