Parameter 0 of method websocketRoutingFilter in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type - spring

Question

I am developing code by taking reference from : https://piotrminkowski.wordpress.com/2018/04/26/quick-guide-to-microservices-with-spring-boot-2-0-eureka-and-spring-cloud/. In this example, I'm using Spring Boot V 2.1.1.RELEASE and spring-cloud-dependencies as Finchley.RELEASE.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Finchley.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
I am getting below error while starting the gateway-service:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Description:
Parameter 0 of method websocketRoutingFilter in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type 'org.springframework.web.reactive.socket.client.WebSocketClient' that could not be found.
The following candidates were found but could not be injected:
- Bean method 'reactorNettyWebSocketClient' in 'GatewayAutoConfiguration.NettyConfiguration' not loaded because #ConditionalOnClass did not find required class 'reactor.ipc.netty.http.client.HttpClient'
Action:
Consider revisiting the entries above or defining a bean of type 'org.springframework.web.reactive.socket.client.WebSocketClient' in your configuration.
And also getting below error while starting proxy-service. How can I resolve this?

Description:
The bean 'proxyRequestHelper', defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$NoActuatorConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/cloud/netflix/zuul/ZuulProxyAutoConfiguration$EndpointConfiguration.class] and overriding is disabled.
Action:
Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

public SwaggerResourcesProvider swaggerResourcesProvider() {
return () -> {
List<SwaggerResource> resources = new ArrayList<>();
properties.getRoutes().values().stream()
.forEach(route -> resources.add(createResource(route.getServiceId(), route.getId(), "2.0")));
return resources;
};
}
private SwaggerResource createResource(String name, String location, String version) {
SwaggerResource swaggerResource = new SwaggerResource();
swaggerResource.setName(name);
swaggerResource.setLocation("/" + location + "/v2/api-docs");
swaggerResource.setSwaggerVersion(version);
return swaggerResource;
}
}
I've seen https://github.com/spring-cloud/spring-cloud-gateway/issues/319, but I still want to use the Spring Boot V2.1.1.RELEASE.
