FluxMonoTestCase.java

package com.example.reactor;

import lombok.extern.slf4j.Slf4j;
import org.junit.jupiter.api.Test;
import reactor.core.publisher.Flux;

import java.time.Duration;

@Slf4j
public class FluxMonoTestCase extends BaseTestCase {
    @Test
    public void concatMap() throws InterruptedException {
        Flux<String> stringFlux1 = Flux.just("a","b","c","d","e","f","g","h","i");
        Flux<Flux<String>> stringFlux2 = stringFlux1.window(2);
        stringFlux2.concatMap(flux1 ->flux1.map(word ->word.toUpperCase())
                .delayElements(Duration.ofMillis(200)))
                .subscribe(x -> System.out.print("->"+x));
        Thread.sleep(2000);
    }
}

BaseTestCase.java

package com.example.reactor;

import java.util.Arrays;
import java.util.List;

public class BaseTestCase {
    protected static final List<Employee> list = Arrays.asList(
            new Employee(1, "Alex", 1000),
            new Employee(2, "Michael", 2000),
            new Employee(3, "Jack", 1500),
            new Employee(4, "Owen", 1500),
            new Employee(5, "Denny", 2000));
}

结果:

->A->B->C->D->E->F->G->H->I
