Spring WebFlux | Static Code Analysis Tool to detect unused Mono / Flux

Question

Is there any static code analysis tool available that can spot at compile-time whether a returned Mono or Flux was not used / subscribed to?
Eg

public Mono<Void> someReactiveMethod() { ... }

// if you forget to subscribe to the returned Mono you will have fun at runtime
someReactiveMethod(); // should raise an error

Answer 1

我认为尚无用于此目的的静态代码检查，但您可能想看一下reactor-core中的PublisherProbe类，让您轻松测试是否已订阅Publisher / Mono / Flux 。
