<a href="https://smallrye.io/smallrye-mutiny/" rel="nofollow noreferrer">Mutiny</a> uses an <a href="https://quarkus.io/blog/reactive-messaging-emitter/" rel="nofollow noreferrer">Emitter</a> when integrating with <a href="https://www.geeksforgeeks.org/asynchronous-synchronous-callbacks-java/" rel="nofollow noreferrer">callback-based APIs</a>;
<a href="https://i.stack.imgur.com/vIMgW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vIMgW.png" alt="You can create a Uni using an emitter. This approach is useful when integrating callback-based APIs" /></a>
<a href="https://smallrye.io/smallrye-mutiny/getting-started/creating-unis" rel="nofollow noreferrer">https://smallrye.io/smallrye-mutiny/getting-started/creating-unis</a>
So MyRequestService, or an underlying callback object, needs to implement an <a href="https://smallrye.io/smallrye-reactive-messaging/smallrye-reactive-messaging/2.5/emitter/emitter.html" rel="nofollow noreferrer">UniEmitter</a> Consumer.
But first, to become <a href="https://en.wikipedia.org/wiki/Reactive_programming" rel="nofollow noreferrer">Reactive</a>, my old blocking REST endpoint needs to return Uni&lt;MyJsonResult&gt; instead of MyJsonResult;
<a href="https://i.stack.imgur.com/N3Xn7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/N3Xn7.png" alt="Uni instead of MyJsonResult" /></a>
The ServiceResource just forwards the call to the Service.

MyRequestService creates a MyJsonResultConsumer and delivers this to the Mutiny Emitter. The resulting Uni&lt;MyJsonResult&gt; is returned to the ServiceResource.
<a href="https://i.stack.imgur.com/sDdas.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sDdas.png" alt="Finally MyJsonResultConsumer is the actual callback object; method ready() calls complete() on the UniEmitter concluding the callback towards Mutiny" /></a>
Finally MyJsonResultConsumer is here the actual callback object; method ready() calls complete() on the UniEmitter concluding the callback towards Mutiny.
Remember that Mutiny needs to provide the UniEmitter with a call(back) to accept(), so you should check for null pointers (or use a <a href="https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/Semaphore.html" rel="nofollow noreferrer">Semaphore</a> oid). ‍♂️

Last week i had my first ✨ rounds with the <a href="https://smallrye.io/smallrye-mutiny/" rel="nofollow noreferrer">Mutiny</a> library because i needed a <a href="https://en.wikipedia.org/wiki/Reactive_programming" rel="nofollow noreferrer">Reactive</a> REST endpoint in my <a href="https://quarkus.io/" rel="nofollow noreferrer">Quarkus</a> project. This was not as obvious as it sounds so i thought i'll share my new insights about the <a href="https://smallrye.io/smallrye-mutiny/" rel="nofollow noreferrer">Mutiny</a> library in <a href="https://quarkus.io/" rel="nofollow noreferrer">Quarkus</a>;
Quarkus <a href="https://www.oreilly.com/library/view/quarkus-cookbook/9781492062646/" rel="nofollow noreferrer">documentation</a> specifies the Mutiny library as the preferred library for Reactive use-cases;
<a href="https://i.stack.imgur.com/KoLJ7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KoLJ7.png" alt="Going forward, Mutiny will be the preferred library within Quarkus for all things reactive." /></a>
For example;
<a href="https://i.stack.imgur.com/fopT1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/fopT1.png" alt="enter image description here" /></a>
what stood out is that most Mutiny examples are using a new String as an example.
So, my question remained;
<blockquote>
how do i connect MyRequestService with Mutiny in Quarkus
</blockquote>
This would be something as:
<pre><code>Uni&lt;MyRequestService&gt; lMyRequestServiceUni = Uni.createFrom().item( ... ) ...
</code></pre>
MyRequestService already uses a callback structure, so I tried a callback method towards Mutiny.

Connect MyRequestService to Reactive REST GET endpoint with Quarkus/Mutiny through callback method

上周，我使用了库进行了第一次✨循环，因为我需要在项目中使用 REST端点。这并不像听起来那么明显，所以我想我将分享我对中的库的新见解；Quarkus 指定突变库为反应用例的首选库；​​例如；​​最突出的是，大多数Mutiny示例都使用了一个新字符串作为示例。因此，我的问题仍然存在；如何将MyRequestService与Quarkus中的Mutiny连接起来这将是如下内容：Uni<MyReques
