叛变 - 项目反应堆的单声道（）fromcallable（）是什么

Question

我是叛变的新手，但对项目反应堆很熟悉。

我正在寻找与Mutiny中的mono.fromcallable（）的对应物，以从可呼叫或匿名lambda创建一个uni？

Answer 1

从lambda创建一个UNI

Uni.createFrom().item(() -> "Testing Uni");

您可以使用以下

Uni.createFrom().future( new FutureTask<>( callable ));

方式 /创建unis“ rel =” nofollow noreferrer“>创建一个uni ：

Uni.createFrom().item(1); // Emit 1 at subscription time
Uni.createFrom().item(() -> x); // Emit x at subscription time, the supplier is invoked for each subscription
Uni.createFrom().completionStage(cs); // Emit the item from this completion stage
Uni.createFrom().completionStage(() -> cs); // Emit the item from this completion stage, the stage is not created before subscription
Uni.createFrom().failure(exception); // Emit the failure at subscription time
Uni.createFrom().deferred(() -> Uni.from().value(x)); // Defer the uni creation until subscription. Each subscription can produce a different uni
Uni.createFrom().nullItem(); // Emit null at subscription time
Uni.createFrom().voidItem(); // Create a Uni not emitting any signal (returns Uni<Void>()
Uni.createFrom().nothing(); // Create a Uni not emitting any signal
Uni.createFrom().publisher(publisher); // Create a Uni from a Reactive Streams Publisher
