Gracefully Shutting Down a Thread Pool in Java

To gracefully shut down a Java thread pool, use ExecutorService's shutdown() to reject new tasks, awaitTermination() to wait for running tasks with optional timeout, handle exceptions, and optionally invoke shutdownNow() for forced termination, as illustrated by code examples from Dubbo3 and RocketMQ.
