I'm using spring webflux WebFilter with kotlin coroutines, currently the only way I can run suspend function in filter function is using runBlocking . Is there a better way for calling a suspend function in that case?

[Dariusz Kuc]

override fun filter(exchange: ServerWebExchange, chain: WebFilterChain): Mono<Void> = mono {
   // call your function here
}

[tvtan]

but chain.filter(exchange) is returning a Mono already

[Dariusz Kuc]

You can await on it

That's what I'm concerned because I can use Mono.awaitSingle() but I'm not sure it will have the same behavior with returning the Mono from chain.filter(exchange) , especially I'm writing a context by using chain.filter(exchange).contextWrite().awaitSingle()
