Spring 框架提供的 CustomizableThreadFactory。

ThreadFactory springThreadFactory = new CustomizableThreadFactory("springThread-pool-");


ExecutorService exec = new ThreadPoolExecutor(1, 1,
		0L, TimeUnit.MILLISECONDS,
		new LinkedBlockingQueue<Runnable>(10),springThreadFactory);
exec.submit(() -> {
	logger.info("--記憶中的顏色是什么顏色---");
});

第二種 ThreadFactoryBuilder

Google guava 工具類 提供的 ThreadFactoryBuilder ,使用鏈式方法創(chuàng)建。

ThreadFactory guavaThreadFactory = new ThreadFactoryBuilder().setNameFormat("retryClient-pool-").build();


ExecutorService exec = new ThreadPoolExecutor(1, 1,
		0L, TimeUnit.MILLISECONDS,
		new LinkedBlockingQueue<Runnable>(10),springThreadFactory);
exec.submit(() -> {
	logger.info("--記憶中的顏色是什么顏色---");
});

第三種 BasicThreadFactory

Apache commons-lang3 提供的 BasicThreadFactory.

ThreadFactory basicThreadFactory = new BasicThreadFactory.Builder()
		.namingPattern("basicThreadFactory-").build();

ExecutorService exec = new ThreadPoolExecutor(1, 1,
		0L, TimeUnit.MILLISECONDS,
		new LinkedBlockingQueue<Runnable>(10),springThreadFactory);
exec.submit(() -> {
	logger.info("--記憶中的顏色是什么顏色---");
});

總結

最終本質都是 給 java.lang.Thread#name 設置名稱,詳情源碼感興趣的可以自行查看。

final Thread thread = new Thread();
thread.setName(name);
