THE Waterfall :
I've got a Mono with an object that contains a list. I need to get that list out of Mono and put it inside Flux.
public Flux<Message> getMessages(String id) {
return chatDAO.findById(id);
}
That findById
method takes an id of a chat and returns Mono<Chat>
where Chat
has a list of messages. I want to take that list of messages and convert it into Flux<Messages>
povisenko :
you can simply use a combination of Mono#flatMapMany and Flux#fromIterable methods in the following way
public Flux<Message> getMessages(String id) {
return chatDAO.findById(id)
.map(Chat::getMessages) //assumes that you have getter for your messages
.flatMapMany(Flux::fromIterable);
}
