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

Java线程池中设置线程名称三种方式

1. CustomizableThreadFactory

Spring 框架提供的 CustomizableThreadFactory。

1 ThreadFactory springThreadFactory = new CustomizableThreadFactory("springThread-pool-");
2     
3 
4 ExecutorService exec = new ThreadPoolExecutor(1, 1,
5         0L, TimeUnit.MILLISECONDS,
6         new LinkedBlockingQueue<Runnable>(10),springThreadFactory);
7 exec.submit(() -> {
8     logger.info("--记忆中的颜色是什么颜色---");
9 });

2. ThreadFactoryBuilder

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

1 ThreadFactory guavaThreadFactory = new ThreadFactoryBuilder().setNameFormat("retryClient-pool-").build();
2 
3 
4 ExecutorService exec = new ThreadPoolExecutor(1, 1,
5         0L, TimeUnit.MILLISECONDS,
6         new LinkedBlockingQueue<Runnable>(10),guavaThreadFactory );
7 exec.submit(() -> {
8     logger.info("--记忆中的颜色是什么颜色---");
9 });

3. BasicThreadFactory

Apache commons-lang3 提供的 BasicThreadFactory.

1 ThreadFactory basicThreadFactory = new BasicThreadFactory.Builder()
2         .namingPattern("basicThreadFactory-").build();
3 
4 ExecutorService exec = new ThreadPoolExecutor(1, 1,
5         0L, TimeUnit.MILLISECONDS,
6         new LinkedBlockingQueue<Runnable>(10),basicThreadFactory );
7 exec.submit(() -> {
8     logger.info("--记忆中的颜色是什么颜色---");
9 });

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。

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