Webflux: No logs when request is filtered

Webflux: No logs when request is filtered out by a WebFilter

Description

In a spring cloud gateway application it is possible (and maybe common) to have a set of global WebFilters which are applied to all requests. It turns out, that having a WebFilter which prevents further request processing (e.g. by returning a 401), prevents logging of the whole request/response by Logbook.

Expected Behavior

All requests/responses should be logged, even if further request processing is cancelled by a WebFilter.

Actual Behavior

Currently there are no logs for affected requests/responses.

Possible Fix

Steps to Reproduce

Add a filter to your application, e.g.:

@Bean
public WebFilter securityFilter() {
    return ((exchange, chain) -> {
        if (exchange.getRequest().getPath().value().equals("/secured")) {
            exchange.getResponse().setStatusCode(HttpStatus.UNAUTHORIZED);
            return exchange.getResponse().setComplete();
        } else {
            return chain.filter(exchange);
        }
    });
}

Context

Your Environment

• SpringBoot 3.1.2
• Logbook 3.2.0
