TransmittableThreadLocal

✓ com.alibaba.ttl.TransmittableThreadLocal

Use TransmittableThreadLocal to propagate a value from main thread to a thread pool task.

import com.alibaba.ttl.TransmittableThreadLocal; TransmittableThreadLocal<String> context = new TransmittableThreadLocal<>(); context.set("main-thread-value"); ExecutorService executor = Executors.newFixedThreadPool(1); executor.submit(() -> { System.out.println(context.get()); // prints "main-thread-value" });

Debug

Known issues

gotchaTransmittableThreadLocal requires explicit TtlRunnable or TtlCallable wrapping for thread pools; otherwise values may not transmit.

fix

Wrap tasks with TtlRunnable.get() or use TtlExecutors.
