问题 It seems that only one http client gets the stream of data, while the others do not. Is it true that the Publisher is hot data, and that it should broadcast to all subscribers? Please find more in Can I allow multiple http clients to consume a Flowable stream of data with resteasy-rxjava2 / quarkus? package org.acme.kafka; import javax.inject.Inject; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; import io.reactivex.Flowable;

问题 Suppose there is a Dao class with the following two methods: 1) delete(items: List<Item>): Completable 2) insert(items: List< Item >): Single<List<Long>> How can I chain them into a @transaction method in Dao class starting with ‘delete method’ and then returning ‘insert method’ result? I want to have a method with a signature like this: @Transaction fun deleteAndInsert(): Single<List<Long> > { ... } 回答1: I'm assuming your main goal is to have the return type of deleteAndInsert() as Single .

问题 Currently I am able to see the streaming values exposed by the code below, but only one http client will receive the continuous stream of values, the others will not be able to. The code, a modified version of the quarkus quickstart for kafka reactive streaming is: @Path("/migrations") public class StreamingResource { private volatile Map<String, String> counterBySystemDate = new ConcurrentHashMap<>(); @Inject @Channel("migrations") Flowable<String> counters; @GET @Path("/stream") @Produces

问题 I'm studying Rxjava2 and I'm trying to integrate the Room Library with Rxjava2. The problem is: I have a populated table and every time I login in the app, I need to delete this table and then insert a new content in database. Separately, the delete and insert works fine, but when I try to insert new values after I delete the table content, the delete method deletes all the new values.. (some parts of the code is in kotlin and others in java) I already tried this: RxJava2 + Room: data is not

问题 This question already has an answer here : How to handle dispose in RxJava without InterruptedException (1 answer) Closed 5 days ago . I have a simple code below compositeDisposable.add(Observable.create<Int> { Thread.sleep(1000) } .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe({}, {Log.d("Track", it.localizedMessage)}, {})) Handler().postDelayed({compositeDisposable.clear()}, 100) It purposely use Thread.sleep(1000) , just to trigger the
