Examples with NamedThreadFactory org.apache.dubbo.common.utils.NamedThreadFactory used on opensource projects

Example 1 with NamedThreadFactory

use of org.apache.dubbo.common.utils.NamedThreadFactory in project dubbo by alibaba.

the class EagerThreadPoolExecutorTest method testEagerThreadPool.

/**
 * It print like this:
 * thread number in current pool：1,  task number in task queue：0 executor size: 1
 * thread number in current pool：2,  task number in task queue：0 executor size: 2
 * thread number in current pool：3,  task number in task queue：0 executor size: 3
 * thread number in current pool：4,  task number in task queue：0 executor size: 4
 * thread number in current pool：5,  task number in task queue：0 executor size: 5
 * thread number in current pool：6,  task number in task queue：0 executor size: 6
 * thread number in current pool：7,  task number in task queue：0 executor size: 7
 * thread number in current pool：8,  task number in task queue：0 executor size: 8
 * thread number in current pool：9,  task number in task queue：0 executor size: 9
 * thread number in current pool：10,  task number in task queue：0 executor size: 10
 * thread number in current pool：10,  task number in task queue：4 executor size: 10
 * thread number in current pool：10,  task number in task queue：3 executor size: 10
 * thread number in current pool：10,  task number in task queue：2 executor size: 10
 * thread number in current pool：10,  task number in task queue：1 executor size: 10
 * thread number in current pool：10,  task number in task queue：0 executor size: 10
 * <p>
 * We can see , when the core threads are in busy,
 * the thread pool create thread (but thread nums always less than max) instead of put task into queue.
