Example 1 with AbortPolicyWithReport

use of org.apache.dubbo.common.threadpool.support.AbortPolicyWithReport 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.
