Java中怎么设置线程池名称

Spring 框架提供的 CustomizableThreadFactory。

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


ExecutorService exec = new ThreadPoolExecutor(1, 1,
          0L, TimeUnit.MILLISECONDS,
         new LinkedBlockingQueue(10),springThreadFactory);
exec.submit(() -> {
       logger.info("--记忆中的颜色是什么颜色---");
});

第二种 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(10),springThreadFactory);
exec.submit(() -> {
       logger.info("--记忆中的颜色是什么颜色---");
});

第三种 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(10),springThreadFactory);
exec.submit(() -> {
       logger.info("--记忆中的颜色是什么颜色---");
});

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);
