How to change the name of threads in an ExecutorService?

Question

I'm using an ExecutorService to execute some Callables, but the name of the threads are like fixed-pool-1-thread-1.

How I change the name of the threads? If it's not possible, there another way to execute Callables that I can set the name of threadS?

I just asked this the other day - http://stackoverflow.com/questions/6113746/naming-threads-and-thread-pools-of-executorservice — mre, May 25 '11 at 14:38

You'll have to use an ExecutorService implementation that allows you to set the ThreadFactory1 used to create threads, for example, ThreadPoolExecutor. Pass an instance that creates threads with the proper names.

There's also a handy class in commons-lang that allows to specify thread names with a pattern: BasicThreadFactory. This keeps you from having to create a ThreadFactory subclass just to provide the naming behavior.

+1, for Javadoc reference and correct/concise answer – mre May 25 '11 at 14:39
There is some native java implementation of the ThreadFactory interface? – Renato Dinhani May 25 '11 at 15:00
@Renato, the only accessible library implementation is from the `Executors` utility class and it does not allow you to supply a name string. – Tim Bender May 25 '11 at 21:58

Guava almost always has what you need. ThreadFactory namedThreadFactory = new ThreadFactoryBuilder().setNameFormat("my-sad-thread-%d").build() and pass it off to your ExecutorService.

A quick and dirty way;

public void run() {
    Thread.currentThread().setName(aName);
    doStuff();
}

This assumes that you can change the run method of the Thread. – Artjom B. Jul 18 '14 at 08:13
