如何为Executors.newScheduledThreadPool（5）设置RemoveOnCancelPolicy

此方法在ScheduledThreadPoolExecutor中声明。

public void setRemoveonCancelPolicy(boolean value) {    removeonCancel = value;}

Executors类通过newScheduledThreadPool和类似方法返回此执行程序。

public static ScheduledExecutorService newScheduledThreadPool(int corePoolSize) {    return new ScheduledThreadPoolExecutor(corePoolSize);}

简而言之，您可以强制转换执行程序服务引用以调用该方法

ScheduledThreadPoolExecutor ex = (ScheduledThreadPoolExecutor) Executors.newScheduledThreadPool(5);ex.setRemoveonCancelPolicy(true);

或

new ScheduledThreadPoolExecutor

ScheduledThreadPoolExecutor ex = new ScheduledThreadPoolExecutor(5);ex.setRemoveonCancelPolicy(true);
