spring集成用于注册动态ServerWebSocketContainer路径，以便可以使用不同的路径创建不同的集成流

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {

    @Autowired
    private WebSocketHandler webSocketHandler;

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        // 注册动态路径
        registry.addHandler(webSocketHandler, "/dynamic-path").setAllowedOrigins("*");
    }
}

@Component
public class WebSocketHandler extends TextWebSocketHandler {

    @Override
    protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
        // 处理收到的消息
        String payload = message.getPayload();
        // ...
    }
}
