/GOF/gof-example/src/main/java/com/ipipman/gof/example/singleton/GOF-Singleton单例模式.md: -------------------------------------------------------------------------------- 1 | ### Singleton 单列模式 2 | 3 | #### 为什么要使用单例？ 4 | 5 | `单例设计模式`（Singleton Design Pattern）理解起来非常简单; 6 | 7 | 一个类只允许创建一个对象（或者实例），那这个类就是一个单例类; 8 | 9 | 使用场景： 10 | 11 | > - 避免资源访问冲突; 12 | > - 表示全局唯一的类; 13 | 14 | 15 | 16 | #### 如果实现一个单例？ 17 | 18 | 实现一个单例，需要关注的点有以下几个方面： 19 | 20 | > - 构造函数需要是 private 访问权限的，这样才能避免外部通过 new 创建实例； 21 | > - 考虑创建对象的线程安全问题； 22 | > - 考虑是否支持延迟加载； 23 | > - 考虑 getInstance() 性能是否高（是否加锁）; 24 | 25 | 26 | 27 | #### 1. 饿汉式 28 | 29 | **饿汉式** 的实现比较简单，在类加载的时候，instance 静态实例已经创建并初始化好了，所以 instance 实例是线程安全的； 30 | 31 | 不过，这样实现方式不支持延迟加载，初始化时可能会耗性能； 32 | 33 | ```java 34 | public class IdGenerator1 { 35 | private AtomicLong id = new AtomicLong(0); 36 | private static final IdGenerator1 instance = new IdGenerator1(); 37 | private IdGenerator1() { 38 | } 39 | public static IdGenerator1 getInstance() { 40 | return instance; 41 | } 42 | public Long getId(){ 43 | return id.incrementAndGet(); 44 | } 45 | } 46 | ``` 47 | 48 | 49 | 50 | #### 2. 懒汉试 51 | 52 | 有饿汉式就有懒汉式； 53 | 54 | **懒汉式** 对于 **饿汉式** 的优势在于它支持延迟加载，不影响初始化性能； 55 | 56 | 不过懒汉试缺点也很明显，我们给 getInstance() 加了一个 synchronized 锁，导致这个方法并发度很低，性能非常差； 57 | 58 | ```java 59 | public class IdGenerator2 { 60 | private AtomicLong id = new AtomicLong(0); 61 | private static IdGenerator2 instance; 62 | private IdGenerator2() { 63 | } 64 | public static synchronized IdGenerator2 getInstance() { 65 | if (instance == null) { 66 | instance = new IdGenerator2(); 67 | } 68 | return instance; 69 | } 70 | public Long getId() { 71 | return id.incrementAndGet(); 72 | } 73 | } 74 | ``` 75 | 76 | 77 | 78 | #### 3. 双重检测 79 | 80 | 饿汉式不支持延迟加载，懒汉式有性能问题，不支持高并发； 81 | 82 | **双重检测** 兼顾了性能和延迟加载问题； 83 | 84 | 在实现方式中，只要 instance 被创建后，即便再调用 getInstance() 函数也不会再进入到加锁逻辑中了； 85 | 86 | ```java 87 | public class IdGenerator3 { 88 | private AtomicLong id = new AtomicLong(0); 89 | private static volatile IdGenerator3 instance; 90 | private IdGenerator3() { 91 | } 92 | public static IdGenerator3 getInstance() { 93 | if (instance == null) { 94 | synchronized (IdGenerator3.class) { 95 | if (instance == null) { 96 | instance = new IdGenerator3(); 97 | } 98 | } 99 | } 100 | return instance; 101 | } 102 | public Long getId() { 103 | return id.incrementAndGet(); 104 | } 105 | } 106 | ``` 107 | 108 | 109 | 110 | #### 4. 静态内部类 111 | 112 | **静态内部类** 它有点类似于饿汉模式，但又能做到延迟加载； 113 | 114 | SingletonHolder 是一个内部静态类，当外部类 IdGenerator4 被加载的时候，并不会创建 SingletonHodler 实例对象； 115 | 116 | 只有在 getInstance() 方式时，SingletonHodler 类才会被加载； 117 | 118 | instance 的唯一性、创建过程的线程安全由 JVM 来保证； 119 | 120 | ```java 121 | public class IdGenerator4 { 122 | private AtomicLong id = new AtomicLong(0); 123 | private IdGenerator4() { 124 | } 125 | private static class SingletonHolder { 126 | public final static IdGenerator4 instance = new IdGenerator4(); 127 | } 128 | public static IdGenerator4 getInstance() { 129 | return SingletonHolder.instance; 130 | } 131 | public Long getId() { 132 | return id.incrementAndGet(); 133 | } 134 | } 135 | ``` 136 | 137 | 138 | 139 | #### 5. 枚举 140 | 141 | 基于 **枚举类型** 的单例实现，这种实现方式通过 Java 枚举类型本身的特性，保证了实例创建的线程安全性和实例的唯一性； 142 | 143 | ```java 144 | public enum IdGenerator5 { 145 | INSTANCE; 146 | private AtomicLong id = new AtomicLong(0); 147 | 148 | public Long getId() { 149 | return id.incrementAndGet(); 150 | } 151 | } 152 | ``` --------------------------------------------------------------------------------

/技术架构/（1）架构的标准定义.md: -------------------------------------------------------------------------------- 1 | ## 架构的标准定义 2 | 3 | 4 | 5 | ### 架构的组成部分 6 | 7 | image-20210825110357585 8 | 9 | 10 | 11 | ### 系统 & 子系统 - 定义 12 | 13 | #### 1、系统 14 | 15 | > 泛指由一群有关联的个体组成，根据某种规则运作； 16 | 17 | #### 2、子系统 18 | 19 | > 由一群有关联的个体所组成的系统，多半会是更大系统中的一部分 20 | 21 | #### 标准定义 22 | 23 | image-20210825110913049 24 | 25 | > 一群有关联的个体，个体之间按规则运作，系统的能力超越个体的能力，自顶向下逐层分解 26 | 27 | 28 | 29 | ### 模块 vs 组件 - 定义 30 | 31 | image-20210825111620645 32 | 33 | #### 1、模块 34 | 35 | > 模块是按逻辑的角度或者业务的角度进行拆分的，比如：用户模块、课程模块 36 | > 37 | > 模块可以理解为系统的个体，在系统下通过模块之前的规则运作，解决的是职责分离 38 | > 39 | > 微服务和DDD设计都属于模块在服务化场景的一种描述 40 | 41 | #### 2、组件 42 | 43 | > 组件是按物理拆分的，每个组件都能独立运行，可以服用在多个系统中 44 | > 45 | > 像Nginx、Mysql、Redis或封装的复用代码包等等，都能称为组件 46 | 47 | 48 | 49 | ### 框架 vs 架构 50 | 51 | image-20210825115240818 52 | 53 | #### 框架 54 | 55 | > 框架特指用软件产品实现了一堆组件的使用规范 56 | > 57 | > 像Spring、脚手架都属于框架 58 | 59 | #### 软件架构 60 | 61 | > 涵盖了架构本身的定义和架构文档的内容 62 | 63

-------------------------------------------------------------------------------- 1 | ### 面向复杂度架构设计 2 | 3 | 4 | 5 | #### DDD 设计的理解 6 | 7 | > DDD 是可扩展架构的设计技巧，不是架构方法论； 8 | > 9 | > DDD 兼顾架构设计和方案设计，大部分人会搞混； 10 | > 11 | > DDD、敏捷架构不关注存储和计算，只关注业务； 12 | 13 | 14 | 15 | #### 整洁架构 16 | 17 | image-20210918111705265 18 | 19 | 20 | 21 | #### 面向复杂度架构-为什么要做架构设计？ 22 | 23 | - 本质：架构设计师为了降低软件系统的复杂度； 24 | - 思路：通过分析系统需求找到系统复杂的地方，然后设计方案； 25 | - 复杂度来源：高性能、高可用、高扩展、安全、成本.... 26 | - 套路：分库分表、缓存、集群、分片、微服务、DDD、异地多活.... 27 | 28 | 29 | 30 | #### 架构设计环 31 | 32 | image-20210918145448472 33 | 34 | 35 | 36 | 37

设计出来的架构要满足当时业务需要，符合团队和技术的能力水平（合适原则） 41 | - 先按照简单的方式设计架构，然后不断地在实际应用过程中迭代优化（简单原则） 42 | - 当业务发生变化时，架构要扩展、重构、甚至重写（演化原则） 43 | 44 | 45 | 46 | #### 架构设计环 47 | 48 | image-20210920155319480 49 | 50 | 51 | 52 |
