public class MdcThreadPoolTaskExecutor
extends org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor

A SLF4J MDC-compatible ThreadPoolExecutor.

In general, MDC is used to store diagnostic information (e.g. logfile name) in per-thread variables, to facilitate logging. However, although MDC data is passed to thread children, this doesn't work when threads are reused in a thread pool. This is a drop-in replacement for ThreadPoolTaskExecutor sets MDC data before each task appropriately.
