深入浅析Java中线程池的原理

// 阻塞队列。private final BlockingQueue<Runnable> workQueue;// 互斥锁private final ReentrantLock mainLock = new ReentrantLock();// 线程集合。一个Worker对应一个线程。private final HashSet<Worker> workers = new HashSet<Worker>();// “终止条件”，与“mainLock”绑定。private final Condition termination = mainLock.newCondition();// 线程池中线程数量曾经达到过的最大值。private int largestPoolSize;// 已完成任务数量private long completedTaskCount;// ThreadFactory对象，用于创建线程。private volatile ThreadFactory threadFactory;// 拒绝策略的处理句柄。private volatile RejectedExecutionHandler handler;// 保持线程存活时间。private volatile long keepAliveTime;private volatile boolean allowCoreThreadTimeOut;// 核心池大小private volatile int corePoolSize;// 最大池大小private volatile int maximumPoolSize;
