提交方法：赢得'；调用onNext流API JAVA

我正在学习Java中的FLOW Stream API，目前我正在创建一个基于上一个示例的示例。问题是我看不到预期的输出，只看到在subscribe方法中打印的订阅字符串。我已经检查并找到了StackOverflow，但是没有工作，因为我已经调用了

request（Long N）

---

为什么没有调用

onNext

方法？

您没有将

ScheduledExecutorService

传递给

发布者，该发布者基本上是一个ExecutorService，它可以安排任务在延迟后运行，或者在每次执行之间以固定的时间间隔重复执行

import java.util.List;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.SubmissionPublisher;

public class Sensor {

    public static void main(String[] args) {
        ScheduledExecutorService executor = Executors.newScheduledThreadPool(Runtime.getRuntime().availableProcessors());
        SubmissionPublisher<String> submissionPublisher = new SubmissionPublisher<>(executor, 5);
        Computer<String> subscriber = new Computer<>();
        submissionPublisher.subscribe(subscriber);

        List<String> items = List.of("1.25", "1.224", "1.55");
        items.forEach(submissionPublisher::submit);
        submissionPublisher.close();
        executor.shutdown();
    }
}

import java.util.List；
导入java.util.concurrent.Executors；
导入java.util.concurrent.ScheduledExecutorService；
导入java.util.concurrent.SubmissionPublisher；
公共类传感器{
公共静态void main（字符串[]args）{
ScheduledExecutorService executor=Executors.newScheduledThreadPool（Runtime.getRuntime（）.availableProcessors（））；
SubmissionPublisher SubmissionPublisher=新SubmissionPublisher（执行者，5）；
计算机订户=新计算机（）；
submissionPublisher.subscribe（订阅者）；
列表项=列表项（“1.25”、“1.224”、“1.55”）；
items.forEach（submissionPublisher:：submit）；
submissionPublisher.close（）；
executor.shutdown（）；
}
}
如何配置传递的执行器，以便发布者以固定速率发布？
import java.util.List;
import java.util.concurrent.SubmissionPublisher;

public class Sensor {

    public static void main(String[] args) {
        SubmissionPublisher<String> submissionPublisher = new SubmissionPublisher<>();
        Computer<String> subscriber = new Computer<>();
        submissionPublisher.subscribe(subscriber);

        List<String> items = List.of("1.25", "1.224", "1.55");
        items.forEach(submissionPublisher::submit);
        submissionPublisher.close();
    }

}

SUBSCRIBING

import java.util.List;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.SubmissionPublisher;

public class Sensor {

    public static void main(String[] args) {
        ScheduledExecutorService executor = Executors.newScheduledThreadPool(Runtime.getRuntime().availableProcessors());
        SubmissionPublisher<String> submissionPublisher = new SubmissionPublisher<>(executor, 5);
        Computer<String> subscriber = new Computer<>();
        submissionPublisher.subscribe(subscriber);

        List<String> items = List.of("1.25", "1.224", "1.55");
        items.forEach(submissionPublisher::submit);
        submissionPublisher.close();
        executor.shutdown();
    }
}
