Yes , I seen org.springframework.boot:spring-boot-starter-webflux:2.0.3.RELEASE dependency onorg.springframework:spring-webflux:5.1.6.RELEASE , but org.springframework:spring-webflux:5.1.6.RELEASE incompatible with org.springframework.cloud:spring-cloud-gateway-core:2.0.3.RELEASE 。

</dependencies>The org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient of org.springframework:spring-webflux:5.1.6.RELEASE is :
public class ReactorNettyWebSocketClient implements WebSocketClient {

.....
}It's second constructor above need a HttpClient object to instance, that mismatched with org/springframework/cloud/gateway/config/GatewayAutoConfiguration$NettyConfiguration.class.
@Bean
public ReactorNettyWebSocketClient reactorNettyWebSocketClient(@Qualifier("nettyClientOptions") Consumer<? super HttpClientOptions.Builder> options) {
return new ReactorNettyWebSocketClient(options);

5 years ago Hi @yjwfn Could you please try it out with Spring Boot Starter 2.0.9.RELEASE and let us know if the problem appears also with that setup?

I upgrade to Spring Boot 2.1.5.RELEASE and Spring Cloud Greenwich.RELEASE already , it's working fine.
This problem I don't have any idea to resolve it, I think it is compatibility problem.

5 years ago yes, but in your issue, you were using the most recent Finchley version with a Spring Boot 2.0.x version that was 6 minors behind the current one. Everything should work on Finchley + Spring Boot 2.0.x, so that's why I've suggested you try out with a more recent 2.0.x Boot (2.0.9.RELEASE).

After try out with Spring Boot Starter 2.0.9.RELEASE the console show :

Description:
An attempt was made to call the method org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient.<init>(Ljava/util/function/Consumer;)V but it does not exist. Its class, org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient, is available from the following locations:

Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.web.reactive.socket.client.ReactorNettyWebSocketClient
You've upgraded spring to 5.1.x with boot 2.0.x which isn't compatible. You'd need to use spring 5.0.x
