ws配置 zuul_zuul+websocket+sockjs

要在Zuul中使用WebSocket和SockJS，您需要进行以下配置：

1. 添加依赖项

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-zuul-websocket</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

2. 配置Zuul路由

zuul:
  routes:
    websocket:
      path: /websocket/**
      url: ws://localhost:8081

这将把所有以“/websocket”开头的请求路由到WebSocket服务器上。

3. 配置SockJS

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/websocket").setAllowedOrigins("*").withSockJS();
    }
}

这将配置一个SockJS端点，它将处理所有以“/websocket”开头的请求，并使用简单的代理模式将消息转发到“/topic”目的地。

4. 启用Zuul

@SpringBootApplication
@EnableZuulProxy
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

这将启用Zuul代理，并将它们路由到相应的WebSocket服务器和SockJS端点。

现在，您应该可以在Zuul中使用WebSocket和SockJS了。
