# 前言 #

笔者在接下来这段时间将对JUC框架内的重点内容进行深度解析，由于内容颇多，需要分成多篇文章，所以在这里列一个目录，方便大家翻阅。

# 目录 #

JUC框架的基础是CAS和自旋，而CAS则是利用`Unsafe`类提供的CAS操作，而原子类则依靠于CAS和自旋。下面几篇文章从源码分析JUC框架内的几个重要的原子类。

*  [JUC AtomicInteger源码解析 JDK8][JUC AtomicInteger_ JDK8]
 *  [JUC AtomicIntegerArray源码解析 JDK8][JUC AtomicIntegerArray_ JDK8]
 *  [JUC AtomicStampedReference源码解析 JDK8][JUC AtomicStampedReference_ JDK8]

ThreadLocal本身不在JUC框架之中，但它却是一种防止多线程竞争的重要手段。

 *  [听说你看过ThreadLocal源码，来面试下这几个问题][ThreadLocal]

AQS（AbstractQueuedSynchronizer）向下依赖了CAS和自旋，向上则提供了一个同步队列的实现，许多JUC框架内中的类都直接使用了AQS作为内部类。下面几篇文章将从AQS提供的几种功能进行深度分析。

*  [AQS深入理解系列（一） 独占锁的获取过程][AQS_]
 *  [AQS深入理解系列（二） 独占锁的释放过程][AQS_ 1]
 *  [AQS深入理解系列（三）共享锁的获取与释放][AQS]
 *  [AQS深入理解系列（四）Condition接口的实现][AQS_Condition]

AQS中有些函数的具体实现细节，并不是很容易让人理解，这些地方一般都是因为考虑了同步队列变化中的中间状态。

*  [AQS深入理解 hasQueuedPredecessors源码分析 JDK8][AQS_ hasQueuedPredecessors_ JDK8]
 *  [AQS深入理解 setHeadAndPropagate源码分析 JDK8][AQS_ setHeadAndPropagate_ JDK8]
 *  [AQS深入理解 doReleaseShared源码分析 JDK8][AQS_ doReleaseShared_ JDK8]
 *  [AQS深入理解 shouldParkAfterFailedAcquire源码分析 状态为0或PROPAGATE的情况分析][AQS_ shouldParkAfterFailedAcquire_ _0_PROPAGATE]
 *  [interrupt()中断对LockSupport.park()的影响][interrupt_LockSupport.park]

JUC框架中有些同步构件依赖了AQS作为实现底层，我们一般使用它们来做到多线程之间的协作。

*  [JUC框架 CountDownLatch源码解析 JDK8][JUC_ CountDownLatch_ JDK8]
 *  [JUC框架 CyclicBarrier源码解析 JDK8][JUC_ CyclicBarrier_ JDK8]
 *  [JUC框架 Semaphore源码解析 JDK8][JUC_ Semaphore_ JDK8]
 *  [JUC框架 ReentrantReadWriteLock源码解析 JDK8][JUC_ ReentrantReadWriteLock_ JDK8]
 *  [ReentrantReadWriteLock 深入理解读锁的非公平实现][ReentrantReadWriteLock]

JUC框架中也提供了各种用途的集合类。

*  [JUC集合类 CopyOnWriteArrayList源码解析 JDK8][JUC_ CopyOnWriteArrayList_ JDK8]
 *  [JUC集合类 CopyOnWriteArraySet源码解析 JDK8][JUC_ CopyOnWriteArraySet_ JDK8]
 *  [JUC集合类 ConcurrentSkipListMap源码解析 JDK8][JUC_ ConcurrentSkipListMap_ JDK8]
 *  [JUC集合类 ConcurrentHashMap源码解析 JDK8][JUC_ ConcurrentHashMap_ JDK8]
 *  [JUC集合类 ConcurrentLinkedQueue源码解析 JDK8][JUC_ ConcurrentLinkedQueue_ JDK8]
 *  [JUC集合类 ConcurrentLinkedDeque源码解析 JDK8][JUC_ ConcurrentLinkedDeque_ JDK8]
 *  [JUC集合类 ArrayBlockingQueue源码解析 JDK8][JUC_ ArrayBlockingQueue_ JDK8]
 *  [JUC集合类 LinkedBlockingQueue源码解析 JDK8][JUC_ LinkedBlockingQueue_ JDK8]
 *  [JUC集合类 LinkedBlockingDeque源码解析 JDK8][JUC_ LinkedBlockingDeque_ JDK8]
 *  [JUC集合类 PriorityBlockingQueue源码解析 JDK8][JUC_ PriorityBlockingQueue_ JDK8]
 *  [JUC集合类 DelayQueue源码解析 JDK8][JUC_ DelayQueue_ JDK8]
 *  [JUC集合类 LinkedTransferQueue源码解析 JDK8][JUC_ LinkedTransferQueue_ JDK8]
 *  [JUC集合类 SynchronousQueue源码解析 JDK8][JUC_ SynchronousQueue_ JDK8]

最后部分将讲解线程池相关源码。

*  [JUC框架 从Runnable到Callable到FutureTask 使用浅析][JUC_ _Runnable_Callable_FutureTask]
 *  [JUC框架 FutureTask源码解析 JDK8][JUC_ FutureTask_ JDK8]
 *  [JUC框架 CompletableFuture源码解析 JDK8][JUC_ CompletableFuture_ JDK8]
 *  [JUC线程池 ThreadPoolExecutor源码解析 JDK8][JUC_ ThreadPoolExecutor_ JDK8]
 *  [JUC线程池 ScheduledThreadPoolExecutor源码解析 JDK8][JUC_ ScheduledThreadPoolExecutor_ JDK8]

至此，本系列文章暂告一段落，以后有机会再来补充。

另外，如果你对JUC框架的源码有什么疑问，最好是去[concurrency-interest][]直接询问大佬，大佬们甚至是Doug Lea本人都会愿意解答的。本人的体验是一个问题去各大中文论坛提问一无所获，甚至去stackoverflow也没人回答问题，还是concurrency-interest比较靠谱。另外，提问前先在搜索引擎找找看（学会百度~），提问时用英文描述清楚（起码让外国人能看懂~）。

# 后记 #

以上文章一般多以源码分析为主，虽不敢保证完全权威，但肯定能为你对JUC的理解铺平道路。
