Spring Flux: How to configure multiple WebFilter

I'm writing a Spring Web Flux application. I have created two WebFilter Component:

AlphaFilter

class AlphaFilter implement WebFilter {
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        // ....
        // Alpha Filter Configurations
        return chain.filter(exchange);
    }
}

AuthenticationFilter

class AuthenticationFilter implement WebFilter {
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        // ....
        // Alpha Filter Configurations
        return chain.filter(exchange);
    }
}

I wanted to ensure that AuthenticationFilter runs before AlphaFilter. How to configure the filters so that AuthenticationFilter runs before AlphaFilter?

Sagar,

Does this part of the documentation answer your question?

In the WebHandler API, you can use a WebFilter to apply interception-style logic before and after the rest of the processing chain of filters and the target WebHandler. When using the WebFlux Config, registering a WebFilter is as simple as declaring it as a Spring bean and (optionally) expressing precedence by using @Order on the bean declaration or by implementing Ordered.
