Mono zipwith The zipWith () method combines the result from this mono and another mono object. Let’s create a few examples to illustrate the usage of static methods in the Flux<T> class such as concat, concatWith, merge, zip and combineLatest. zipWith and zipWhen have an overloaded variants with combiner argument, so using this combiner u can directly tell how to build your response. Same techniques can be applied with Mono as well. Next, we’ll set up a simple example involving user data storage and email. . For your specific condition, you need Mono. zipWith(source2) . getT1(). response. io/docs/core/release/api/reactor/core/publisher/Mono. html#zipWhen-java. U can check the explanation here: https://projectreactor. out::println); Mono: In our examples above we had seen only Flux sources. In the non-static version of the method, it can only combine with a single publisher. The methods take two parameters: monos which is a collection of mono, a combinator which combines sources provided to a Mono. R' -> ? extends R. O'[] -> ? super Object[] M' -> ? extends Mono<?> Zip up to 8 elements and request data up to T8 (). zipWhen() which will ensure that your 3rd service call will have the data it requires from the response from service call 1. BiFunction- Example: zipWith: By this time, I am sure you know what it is for! source1. util. zipWith(secondMono, function ZipWith is available for both Mono and Flux. Reactive java: Combining Mono calls using zipWith() method, and basics to remember prior to the usage of the zipWith() method. just("other thing"); val thirdMono = firstMono. Mono publisher has two zip methods that have similar operations. function. In this tutorial, we’ll explore how we can use zipWhen () to combine the results of two or more Mono streams in a coordinated manner. We’ll start with a quick overview. I have a Mono that I want to combine with another Mono, as in: val firstMono = Mono. I have a Mono that I want to combine with another Mono, as in: val firstMono = Mono. getT1();//response from mono1. getT2();//response from mono 2. just("thing"); val secondMono = Mono. flatMap () - Transform the item emitted by this Mono asynchronously, returning the value emitted by another Mono (possibly changing the value type). R -> Resource Type. This function is used when we already have a data (like A1) and want to combine it with another one that we Given a scenario when one has to work with Flux<T> or Mono<T>, there are different ways to combine streams.
