核心线程池是否已满
创建新的线程执行任务
待执行任务队列是否已满
线程池是否已满
饱和策略处理
放入待执行任务队列
在核心线程池未满的情况下，新提交的任务总是新建线程执行超过核心线程池大小的空闲线程在keepAliveTime之后将被终止，但是，核心线程池在keepAliveTime大于0的情况下，也是可以使用timeout策略

线程池排队策略
Direct Handoffs (e.g. SynchronouseQueue)
读写互锁，只有写入才能读取，读取才能写入需避免设置最大线程池大小，否则，容易导致拒绝新提交任务在处理一系列具有内部依赖关系的请求时，可以避免锁定
Unbounded queues (e.g. LinkedBlockingQueue)
无限制队列，线程池中的线程不会超过核心线程池大小适用于任务相互独立，比如web请求，排队的速度超过处理的速度
Bounded queues(e.g. ArrayBlockingQueue)
通过设置有限的线程来避免资源被耗尽需要同时考虑队列和线程池大小，控制、调优相对来说比较困难大队列，小线程池可能导致较低的吞吐量；较小队列，通常需要较大的线程池，从而增加线程调度负担，也会影响吞吐量
线程池拒绝策略
当Executor处于shutdown状态或者已经超出最大线程池大小，将使用reject策略，拒绝策略分为四类：
中止策略（AbortPolicy）调用者运行策略(CallerRunsPolicy)丢弃策略(DiscardPolicy)丢弃最老的任务策略(DiscardOldestPolicy)
线程池终止（Finalization）
线程池不再使用，并且没有线程（含核心线程），将自动终止如果想在不调用shutdown的情况下，不再使用的线程池自动终止，需要设置allowCoreThreadTimeOut
