Java線程池中設置線程名稱三種方式

本文講一下Java線程池中創建 ThreadFactory 設置線程名稱的三種方式。具體內容如下圖所示

 

 1. CustomizableThreadFactory

   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---");
});

2. ThreadFactoryBuilder

Google guava 工具類 提供的 ThreadFactoryBuilder ,使用鏈式方法創建。

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


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

3. 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),basicThreadFactory );
exec.submit(() -> {
    logger.info("--記憶中的顏色是什么顏色---");
});

4. 三種方式總結

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);
