FluxMonoTestCase.java

package com.example.reactor;

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

@Slf4j
public class FluxMonoTestCase extends BaseTestCase {
    @Test
    public void map() {
        Flux<Employee> employeeFlux = Flux.fromIterable(list);
        employeeFlux.filter(employee -> employee.getSalary() == 2000)
                .map(employee -> {
                    Leader leader = new Leader();
                    leader.setName(employee.getName());
                    leader.setSalary(employee.getSalary());

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));
}
