Support Websockets in gateway server webmvc #3442

Open eljefe6a opened 2 days ago

eljefe6a commented 2 days ago

I'm trying to get the secure websocket or non-secure websockets to work with the gateway in version 4.1.4. I get the same error using wss or ws.

I'm getting this error on startup:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'routerFunctionMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Error creating bean with name 'gatewayCompositeRouterFunction': Error creating bean with name 'scopedTarget.gatewayRouterFunctionHolder': Failed to instantiate [org.springframework.cloud.gateway.server.mvc.config.GatewayMvcPropertiesBeanDefinitionRegistrar$RouterFunctionHolder]: Factory method 'routerFunctionHolderSupplier' threw exception with message: Unable to find HandlerFunction for scheme: wss

This is my application.yml:

  cloud:
    gateway:
      mvc:
        routes:
        - id: websocket
          uri: wss://example.com:9443
          predicates:
            - Path=/example/**

Here is the dependency:

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway-mvc</artifactId>
            <version>4.1.4</version>
        </dependency>

Is there something misconfigured?

Yes, websockets are not supported yet in MVC gateway

So they're supported in the spring-cloud-starter-gateway?
