SpringCloudGateway转发WebSocket请求、以及静态路由

SpringCloudGateway转发WebSocket请求

1、WebSocket

1. 依赖

   <dependency>
       <groupId>org.springframework.bootgroupId>
       <artifactId>spring-boot-starter-websocketartifactId>
   dependency>
   

2. 配置类 WebSocketConfig

   @Configuration
   public class WebSocketConfig {
        
       @Bean
       public ServerEndpointExporter serverEndpointExporter() {
        
           return new ServerEndpointExporter();
       }
   }
   

3. 业务类 WebSocketServer

   @ServerEndpoint("/websocket/{username}")
   @Component
   public class WebSocketServer {
        
       /** 记录当前在线连接数，保证线程安全 */
       private static AtomicInteger onlineNum = new AtomicInteger();
       /** 存放 WebSocketServer 对象 */
       private static ConcurrentHashMap<String, Session> sessionPools = new ConcurrentHashMap<>();
   
       public void sendMessage(Session session, String message) throws IOException {
        
           session.getBasicRemote().sendText(message);
       }
       
       public void sendInfo(String userName, String message) throws IOException {
        
           Session session = sessionPools.get(userName);
           sendMessage(session, message);
       }
   
       @OnOpen
       public void
