Java线程池中设置线程名称三种方式

本文讲一下Java线程池中创建 ThreadFactory 设置线程名称的三种方式。具体内容如下图所示

 

 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("--记忆中的颜色是什么颜色---");
});

2. ThreadFactoryBuilder

Google guava 工具类 提供的 ThreadFactoryBuilder ,使用链式方法创建。

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("--记忆中的颜色是什么颜色---");
});

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("--记忆中的颜色是什么颜色---");
});

4. 三种方式总结

最终本质都是 给 java.lang.Thread#name 设置名称,详情源码感兴趣的可以自行查看。

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