Class AbortPolicyWithReport

java.lang.Object

java.util.concurrent.ThreadPoolExecutor.AbortPolicy

cn.sliew.milky.thread.rejected.policy.AbortPolicyWithReport

All Implemented Interfaces:

XRejectedExecutionHandler, RejectedExecutionHandler

public class AbortPolicyWithReport
extends ThreadPoolExecutor.AbortPolicy
implements XRejectedExecutionHandler

fixme: 提供关闭 dump 线程池开关，dump 线程池是一个 debug 功能，在生产环境应该关闭 debug 类功能。 当发生线程池打满的情况时，另起一个线程 dump 线程池以便排查线上问题。 支持强制执行策略。如果使用的不是固定大小的工作队列，当线程池队列满了的时候会一直等待入队。没有采用 CallerRunsPolicy 策略的原因是线程池会阻塞主线程执行任务，不太合适。
