Description: !!!Java 高并发多线程编程系列 demo 代码&教程&面试题集锦! !! 包括但不限于线程安全性, atomic包下相关类、CAS原理、Unsafe类、synchronized关键字等的使用及注意事项,volatile关键字的规则和使用，及synchronized关键字的可见性,happens-before原则 安全发布对象的一些核心方法方式,线程安全策略定义不可变对象、线程封闭、同步容器、并发容器等.\,AQS模型设计及相关同步组件的原理和使用，都非常实用，具体包括：CountDownLatch、Semaphore、CyclicBarrier、ReentrantLock与锁、Condition等,FutureTask、Fork/Join框架、BlockingQueue，其中FutureTask讲解时会对比着Callable、Runnable、Future来讲,线程调度-线程池 J.U.C里最后一部分：线程池,ThreadPoolExecutor详细介绍（参数、状态、方法）、线程池类图、Executor框架接口等进行讲解，需要大家能了解线程池的许多细节及配置，并能在实际项目中正确使用 多线程并发拓展讲解 对并发编程做些补充，但都贴近当前的面试，主要讲解死锁产生的条件及预防、多线程并发编程的最佳实践、Spring与线程安全、以及面试都特别喜欢问的HashMap和ConcurrentMap源码细节。当然，面试喜欢问的问题，对实际项目开发也是特别重要的 高并发之扩容 高并发部分：思路，侧重面试，扩容思路，首先介绍垂直扩容和水平扩容的区别，之后介绍数据库读操作扩展和写操作扩展思路。 高并发之缓存 思路，本章讲解高并发中缓存方案。 包含对缓存特征（命中率、最大元素、清空策略）、影响缓存命中率因素、缓存分类和应用场景（本地缓存、分布式缓存）、高并发场景下缓存常见问题（缓存一致性、缓存并发、缓存穿透、雪崩）等的具体介绍。此外，针对大家常用的缓存组件Guava Cache、Memcache、Redis 高并发之消息队列 思路，本章介绍了消息队列的特性（业务无关、FIFO、容灾、性能）、为什么需要消息队列以及消息队列的好处（业务解耦、最终一致性、广播、错峰与流控），最后对当前比较流行的消息队列组件kafka和rabbitmq做了架构分析和特性介绍 高并发之应用拆分 从实际项目拆分步骤讲起，让大家可以实际感受到应用拆分的好处和解决的问题，之后引出对应用拆分原则（业务优先、循序渐进、兼顾技术、可靠测试）和应用拆分时思考的内容（应用之间通信、应用之间数据库设计、避免事务跨应用），并引出对服务化Dubbo和微服务Spring Cloud的框架介绍 高并发之应用限流,自动降级（超时、失败次数、故障、限流）和人工降级（开关） - Activity · Cook-R/Java-Concurrency-Progamming-Tutorial
