Class BlockPolicy

java.lang.Object

cn.hutool.core.thread.BlockPolicy

All Implemented Interfaces:

RejectedExecutionHandler

public class BlockPolicy
extends Object
implements RejectedExecutionHandler

当任务队列过长时处于阻塞状态，直到添加到队列中 如果阻塞过程中被中断，就会抛出InterruptedException异常
有时候在线程池内访问第三方接口，只希望固定并发数去访问，并且不希望丢弃任务时使用此策略，队列满的时候会处于阻塞状态(例如刷库的场景)

Since:

5.8.0
