RxJava NewThread调度器

RxJava NewThread调度器

Schedulers.newThread()方法创建并返回一个调度器,该调度器为每个工作单元创建一个新的线程。

Schedulers.newThread()示例

使用您选择的任何编辑器,在C:> RxJava中创建以下Java程序。

ObservableTester.java

import java.util.Random;

import io.reactivex.Observable;
import io.reactivex.schedulers.Schedulers;

public class ObservableTester  {
   public static void main(String[] args) throws InterruptedException {
      Observable.just("A", "AB", "ABC")
         .flatMap(v -> getLengthWithDelay(v)
         .doOnNext(s -> System.out.println("Processing Thread " 
            + Thread.currentThread().getName()))
         .subscribeOn(Schedulers.newThread()))
         .subscribe(length -> System.out.println("Receiver Thread " 
            + Thread.currentThread().getName() 
            + ", Item length " + length));

         Thread.sleep(10000);
   }
   protected static Observable<Integer> getLengthWithDelay(String v) {
      Random random = new Random();
      try {
         Thread.sleep(random.nextInt(3) * 1000);
         return Observable.just(v.length());
      } catch (InterruptedException e) {
         e.printStackTrace();
      }
      return null;
   }
}

验证结果

使用javac编译器编译该类,如下所示:

C:\RxJava>javac ObservableTester.java

现在按照以下步骤运行ObservableTester:

C:\RxJava>java ObservableTester

它应该产生以下输出 ―

Processing Thread RxNewThreadScheduler-1
Receiver Thread RxNewThreadScheduler-1, Item length 1
Processing Thread RxNewThreadScheduler-2
Receiver Thread RxNewThreadScheduler-2, Item length 2
Processing Thread RxNewThreadScheduler-3
Receiver Thread RxNewThreadScheduler-3, Item length 3
