import com.alibaba.ttl.TransmittableThreadLocal;
import reactor.core.publisher.Mono;
import reactor.core.scheduler.Schedulers;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class Test {

    private final TransmittableThreadLocal<Integer> context = new TransmittableThreadLocal<>();

    private final ThreadLocal<Integer> context2 = new InheritableThreadLocal<>();

    private final ExecutorService threadPool = Executors.newFixedThreadPool(10);

    public static void main(String[] args) throws InterruptedException {
        Test test = new Test();
        for (int i = 100; i < 110; i++) {
            test.test(i);
            Thread.sleep(1000);
        }
    }

    public void test(int i) {
        context.set(i);
        context2.set(i);
        System.out.println("===============Start===============" + i);
        Mono.fromRunnable(() -> {
                    System.out.println("boundedElastic============ttl============" + context.get());
                    System.out.println("boundedElastic============IT============" + context2.get());
                })
                .subscribeOn(Schedulers.boundedElastic())
                .doOnSubscribe(subscription -> System.out.println("Task submission successful:" + i))
                .doFinally(signal -> System.out.println("Task completion signal:" + signal))
                .subscribe();
        context.remove();
        context2.remove();
    }
}

The above is a test case.
