convert Flux<String> to Mono<List<String>>

[hauner]

webflux serialization has a problem to convert a List<String> to Flux<String>. Spring deserializes the list to a single string.

the processor could automatically detect multi wrapper with String type and generate Mono<List<String>> instead of Flux<String>.

Flux seems more correct than Mono<List>. do you have an example?

Can't remember exactly, i guess it is about spring-projects/spring-framework#22662
