类 ThreadPoolExecutors

java.lang.Object

cn.ponfee.disjob.common.concurrent.ThreadPoolExecutors

public final class ThreadPoolExecutors
extends Object

 Thread pool executor utility
   1）maximumPoolSize + CALLER_RUNS：线程池中的线程执行完后，需要等待当前线程执行完后再提交任务
   2）keepAliveTimeSeconds：为0则表示线程立即终止
   3）allowCoreThreadTimeOut：设置为true时，keepAliveTimeSeconds必须大于0
