How to Achieve Asynchronous Thread‑Pool Traceability in Spring Boot with MDC

In high‑concurrency microservices, Spring Boot's default async thread pool loses the MDC‑based traceId, making log correlation impossible; this article shows how to capture the traceId in a filter, propagate it with a custom ThreadPoolTaskExecutor and MDC task decorator, and extend the solution to Feign, RestTemplate, and RestClient while demonstrating a price‑aggregation use case.
