Spring5框架入门基础

Spring5框架概述

• Spring是轻量级的开源的JavaEE框架。
  
• Spring可以解决企业应用开发的复杂性。
  
• Spring有两个核心部分：IOC和AOP
  
  
  
  • IOC：控制反转，把创建对象过程交给Spring进行管理
    
  • AOP：面向切面，不修改源代码进行功能增强
    
  
  
• Spring特点
  
  
  
  • 方便解耦，简化开发（IOC可以降低耦合性）
    
  • AOP编程支持
    
  • 方便程序测试（Spring对Junit4支持，可以通过注解方便的测试Spring程序）
    
  • 方便和其他框架进行整合
    
  • 方便进行事务操作
    
  • 降低API开发难度
    
  
  
• Spring5系统结构
  ​<bean id="emp"  autowire="byName">
  <bean id="emp"  autowire="byType">
         
  </bean>
  <bean id="dept" ></bean>
  </bean>
  <bean id="dept" ></bean>
  

IOC

概念和原理

什么是IOC

• 控制反转，把对象创建和对象之间的调用过程，交给Spring进行管理
  
• 使用IOC目的：为了降低耦合度
  

IOC底层原理

xml解析、工厂模式、反射

• 原始方式与工厂模式的对比
  ​<bean id="emp"  autowire="byName">
  <bean id="emp"  autowire="byType">
         
  </bean>
  <bean id="dept" ></bean>
  </bean>
  <bean id="dept" ></bean>
  
• 画图讲解IOC底层原理
  ​<bean id="emp"  autowire="byName">
  <bean id="emp"  autowire="byType">
         
  </bean>
  <bean id="dept" ></bean>
  </bean>
  <bean id="dept" ></bean>
  

IOC之BeanFactory接口

• IOC思想基于IOC容器完成，IOC底层就是对象工厂
  
• Spring提供IOC容器实现两种方式：（两个接口）
  
  
  
  • BeanFactory：IOC容器基本实现，是Spring内部的使用接口，不提供开发人员进行使用
    

    加载配置文件时不会创建对象，在获取对象（使用）才去创建对象
    

    
    
  • ApplicationContext：BeanFactory接口的子接口，提供更多更强大的功能，一般由开发人人员进行调用
    

    加载配置文件时会把在配置文件对象进行创建
    

    
    
  
  
• ApplicationContext接口有实现类
  ​<bean id="emp"  autowire="byName">
  <bean id="emp"  autowire="byType">
         
  </bean>
  <bean id="dept" ></bean>
  </bean>
  <bean id="dept" ></bean>
  
  
  
  • FileSystemXmlApplicationContext
    configLocation：要写上配置文件在系统盘(某个盘)里的路径
    
  • ClassPathXmlApplicationContext
    configLocation：要写上类路径
    
  
  

IOC操作Bean管理

概念

• 什么是Bean管理
  Bean管理指的是两个操作：Spring创建对象和Spring注入属性
  
• Bean管理操作的方式：
  
  
  
  • 基于xml配置文件方式实现
    
  • 基于注释方式实现
    
  
  

基于xml方式

• 创建对象
  1. [/code][list=1]
  2. [*]在Spring配置文件中，使用bean标签，[b]标签里面添加对应属性，就可以实现对象创建[/b]
  3. [*]bean标签常用的属性
  4. [list]
  5. [*]id属性：[b]唯一标识[/b]
  6. [*]class属性：类全路径（包类路径）
  7. [/list]
  8. [*]创建对象时候，[b]默认执行无参构造方法[/b]
  9. [/list]
  10. [*][b]注入属性[/b]
  11. [list]
  12. [*][b]DI：依赖注入（Dependency
  13. <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
  14. </bean>Injection），就是注入属性[/b]
  15. [indent]DI是一种设计模式，用于管理对象之间的依赖关系，它将创建和管理对象的责任转移给了第三方的容器或框架，从而降低了系统的耦合度。
  16. [/indent]
  17. [/list][list=1]
  18. [*]第一种注入方式：[b]使用set方法进行注入[/b]
  19. [list=1]
  20. [*][i]创建类，定义属性和对应的set方法[/i]
  21. [code]
  22. <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
  23. </bean>/**
  25. <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">

p名称空间注入（了解）
使用p名称空间注入，可以简化基于xml配置方式

• 添加p名称空间在配置文件中
  1. [/code]
  2. [*]进行属性注入，在bean标签里面进行操作
  3. [code]
  4. <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
  5. </bean>

  复制代码

xml注入其他类型属性

• 字面量
  
  
  
  • null值
    2. <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">

FactoryBean

• Spring有两种类型bean,一种普通bean,另一种工厂bean(FactoryBean)
  
• 普通bean：在配置文件中定义bean类型就是返回类型
  
• 工厂bean：在配置文件中定义bean类型可以和返回类型不一样
  

第一步，创建类，让这个类作为工厂bean，实现接口FactoryBean
第二步，实现接口里面的方法，在实现的方法中定义返回的bean类型

bean作用域

• 在Spring里面，设置创建bean实例可以是单实例，也可以是多实例
  
• 在Spring里面，默认情况下，bean是单实例对象

  以上例子的两个输出是相同的，说明bean默认是单实例对象。
  
• 如何设置单实例or多实例
  
  
  
  • 在Spring配置文件bean标签里面有属性scope，用于设置单实例还是多实例
    
  • scope属性值
    
    
    
    • singleton：表示单实例对象（默认值）
      
    • prototype：表示多实例对象

  以上例子的两个输出不同，说明此时bean是多实例对象。
  
  

• singleton和prototype区别
  
  
  • singleton表示单实例，prototype表示多实例
    
  • 设置scope值singleton时候，加载spring配置文件就会创建一个单实例对象
    
  • 设置scope值是prototype时候，不是在加载spring配置文件时候创建对象，在调用getBean方法时候创建多实例对象
    
  
  

bean生命周期

• 生命周期：从对象创建到对象销毁的过程
  
• bean生命周期
  
  
  
  • 通过构造器创建bean实例（无参构造）
    
  • 为bean的属性设置值和对其他bean的引用（调用set方法）
    
  • 调用bean的初始化的方法（需要进行配置初始化的方法）
    
  • bean可以使用了（对象获取到了）
    
  • 当容器关闭的时候，调用销毁bean的方法（需要配置销毁的方法）
    
  
  
• 演示bean生命周期

• bean的后置处理器，bean生命周期有七步
  
  
  
  • 通过构造器创建bean实例（无参构造）
    
  • 为bean的属性设置值和对其他bean的引用（调用set方法）
    
  • 把bean实例传递到bean后置处理器的方法postProcessBeforeInitialization
    
  • 调用bean的初始化的方法（需要进行配置初始化的方法）
    
  • 把bean实例传递到bean后置处理器的方法postProcessAfterInitialization
    
  • bean可以使用了（对象获取到了）
    
  • 当容器关闭的时候，调用销毁bean的方法（需要配置销毁的方法）
    
  
  
• 演示添加后置处理器效果
  
  
  
  • 创建类，实现接口BeanPostProcessor，创建后置处理器

xml自动装配

• 自动装配：根据指定的装配规则（属性名称或者属性类型），Spring自动将匹配的属性值注入
  
• 实现自动装配：bean标签属性autowire,配置自动装配
  autowire属性常用两个值:
  byName根据属性名称注入，注入值bean的id值和类属性名称一样
  byType根据属性类型注入
  
• 演示自动装配过程
  
  
  
  • 根据属性名称自动注入
    1. <bean id="emp"  autowire="byName">
    2. <bean id="emp"  autowire="byType">
    3.        
    4. </bean>
    5. <bean id="dept" ></bean>
    6. </bean>
    7. <bean id="dept" ></bean>

    复制代码
  • 根据属性类型自动注入
    1. <bean id="emp"  autowire="byName">
    2. <bean id="emp"  autowire="byType">
    3.        
    4. </bean>
    5. <bean id="dept" ></bean>

基于注解方式

• 什么是注解
  
  
  
  • 注解是代码特殊标记，格式注解名称(属性名称=属性值，属性名称=属性值)
    
  • 使用注解，注解作用在类上面，方法上面，属性上面
    
  • 使用注解目的：简化xml配置
    
  
  
• Spring针对Bean管理中创建对象提供注解
  
  
  
  • @Component
    
  • @Service
    
  • @Controller
    
  • @Repository
    

  以上四个注解功能是一样的，都可以用来创建bean实例
  

  
  
• 基于注解方式实现对象创建
  
  
  
  • 引入依赖
    
    
  • 开启组件扫描

    2. [*]创建类，在类上面添加创建对象注解
    3. [code]//在注解里面value属性值可以省略不写//默认值是类名称，首字母小写//UserService

AOP

概念

什么是AOP？

• 面向切面编程（方面），利用AOP可以对业务逻辑的各个部分进行隔离，从而使得业务逻辑各部分之间的耦合性降低，提高程序的可重用性，同时提高了开发的效率。
  
• 通俗描述：不通过修改源代码方式，在主干功能里面添加新功能
  
• 使用登录例子说明AOP
  

底层原理

AOP底层使用动态代理

• 有接口代理，使用JDK动态代理
  
  
  
  • 创建接口实现类代理对象，增强类的方法
    
  
  
• 没有接口情况，使用CGLIB动态代理
  
  
  
  • 创建子类的代理对象，增强类的方法
    
  
  

JDK动态代理

• 使用JDK动态代理，使用Proxy类里面的方法创建代理对象
  

  Proxy类是属于java.lang包中的
  

  
  
  
  
  • 调用newProxyInstance方法
    static
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>Object
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>newProxyInstance(ClassLoader
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>loader,
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>类[]
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>interfaces,
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>InvocationHandler
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>h)
    返回指定接口的代理类的实例，该接口将调用分派给指定的调用处理程序。
    参数：
    ​<bean id="emp"  autowire="byName">
    <bean id="emp"  autowire="byType">
           
    </bean>
    <bean id="dept" ></bean>
    </bean>
    <bean id="dept" ></bean><bean id="emp"  autowire="byName">
    <bean id="emp"  autowire="byType">
           
    </bean>
    <bean id="dept" ></bean>
    </bean>
    <bean id="dept" ></bean>第一个参数：类加载器
    ​<bean id="emp"  autowire="byName">
    <bean id="emp"  autowire="byType">
           
    </bean>
    <bean id="dept" ></bean>
    </bean>
    <bean id="dept" ></bean><bean id="emp"  autowire="byName">
    <bean id="emp"  autowire="byType">
           
    </bean>
    <bean id="dept" ></bean>
    </bean>
    <bean id="dept" ></bean>第二个参数：增强方法所在类，这个类实现的接口，支持多个接口
    ​<bean id="emp"  autowire="byName">
    <bean id="emp"  autowire="byType">
           
    </bean>
    <bean id="dept" ></bean>
    </bean>
    <bean id="dept" ></bean><bean id="emp"  autowire="byName">
    <bean id="emp"  autowire="byType">
           
    </bean>
    <bean id="dept" ></bean>
    </bean>
    <bean id="dept" ></bean>第三个参数：实现这个接口InvocationHandler，创建代理对象，写增强的部分
    
  
  
• 编写JDK动态代理代码
  
  
  
  • 创建接口，定义方法
    1. public

术语

• 连接点(Jointpoint)：类里面哪些方法可以被增强，这些方法被称为连接点。（类中可以被增强的方法）
  
• 切入点(Pointcut)：实际被真正增强的方法
  
• 增强(Advice)：指的是在目标对象的方法调用前、后或抛出异常时，通过动态代理技术在目标对象的方法周围插入拦截器的逻辑代码，从而实现对目标对象方法的增强和定制。
  
• 通知（增强）：实际增强的逻辑部分。通知定义了增强在何时被调用，并指定了增强的类型。
  

  通知有多种类型：
  

  
  
  • 前置通知
    
  • 后置通知
    
  • 返回增强
    
  • 环绕通知
    
  • 异常通知
    
  • 最终通知
    

  
  
• 切面/方面(Aspect)：把通知应用到切入点的过程（动作）
  

AOP操作——准备工作

• Spring框架一般基于AspectJ实现AOP操作
  
  
  
  • AspectJ不是Spring组成部分，独立AOP框架，一般把AspectJ和Spring框架一起使用，进行AOP操作
    
  
  
• 基于AspectJ实现AOP操作
  
  
  
  • 基于xml配置文件实现
    
  • 基于注解方式实现（使用）
    
  
  
• 在项目工程里面引入AOP相关依赖
  
• 切入点表达式
  
  
  
  • 作用：知道对哪个类里面的哪个方法进行增强
    
  • 语法结构：execution([权限修饰符]
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>[返回类型]
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>[类全路径]
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>[方法名称]
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>[参数列表])
    

    举例1：
    对com.atguigu.dao.BookDao类里面的add进行增强：execution(*
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>com.atguigu.dao.BookDao.add(..))
    举例2：
    对com.atguigu.dao.BookDao类里面的所有方法进行增强：execution(*
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>com.atguigu.dao.BookDao.*(..))
    举例3：
    对com.atguigu.dao包里面所有类，类里面的所有方法进行增强：execution(*
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>com.atguigu.dao*.*(..))

  事务管理
  
  概念
  
  
  
  
  • 什么是事务？
    事务是数据库操作最基本的单元，逻辑上一组操作，要么都成功，如果有一个失败所有操作都失败
    

    
    
    • 典型场景：银行转账
      

    
    

    
    
    • lucy转账100元给mary
      
    • lucy少100,mary多100
      

    
    
  • 事务的四个特性（ACID）
    
    
    
    • 原子性
      
    • 一致性
      
    • 隔离性
      
    • 持久性
      
    
    
  
  搭建事务操作环境
  
  
  
  
  
  • 创建数据库表，添加数据

  Spring事务管理介绍
  
  
  
  
  • 事务添加到JavaEE三层结构里面Service层(业务逻辑层)
    
  • 在Spring进行事务管理操作有两种方式：编程式事务管理和声明式事务管理（使用）
    
  • 声明式事务管理
    
    
    
    • 基于注解方式（使用）
      
    • 基于xml配置文件方式
      
    
    
  • 在Spring进行声明式事务管理，底层使用AOP原理
    
  • Spring事务管理API：PlatformTransactionManager
    PlatformTransactionManager接口，代表事务管理器，这个接口针对不同的框架提供不同的实现类
    
  
  注解声明式事务管理
  
  
  
  
  • 在Spring配置文件配置事务管理器

  • 在service类上面（获取service类里面方法上面）添加事务注解
    
    
    
    • @Transactional，这个注解添加到类上面，也可以添加到方法上面
      
    • 如果把这个注解添加到类上面，这个类里面的所有的方法都添加事务
      
    • 如果把这个注解添加到方法上面，为这个方法添加事务
      
    1. @Service@Transactionalpublic

  声明式事务管理参数配置
  
  在service类上面添加注解@Transactional，在这个注解里面可以配置事务相关参数。
  
  
  
  
  • propagation：事务传播行为
    多事务方法直接进行调用，这个过程中事务是如何进行管理的
    事务的传播行为可以由传播属性指定。Spring定义了7种类传播行为。
    传播属性描述REQUIRED如果有事务在运行，当前的方法就在这个事务内运行，否则，就启动一个新的事物，并在自己的事务内运行REQUIRED_NEW当前的方法必须启动新事物，并在它自己的事务内运行，如果有事务正在运行，应该将它挂起SUPPORTS如果有事务在运行，当前的方法就在这个事务内运行，否则它可以不运行在事务中NOT_SUPPROTS当前的方法不应该运行在事务中，如果有运行的事务，将它挂起MANDATORY当前的方法必须运行在事物内部，如果没有正在运行的事务，就抛出异常NEVER当前的方法不应该运行在事务中，如果有运行的事务，就抛出异常NESTED如果有事务在运行，当前的方法就应该在这个事务的嵌套事务内运行。否则，就启动一个新的事务，并在它自己的事务内运行

  • isolation：事务隔离级别
    
    
    • 事务有特性称为隔离性，多事务操作之间不会产生影响。不考虑隔离性产生很多问题
      
    • 有三个读的问题：脏读、不可重复读、虚读/幻读
      
      
      
      • 脏读：一个未提交事务读取到另一个未提交事务的数据
        
      • 不可重复读：一个未提交事务读取到另一提交事务修改的数据
        
      • 虚读：一个未提交事务读取到另一个提交事务添加数据

  Spring5框架新功能
  
  整个Spring5框架的代码基于Java8,运行时兼容JDK9，许多不建议使用的类和方法在代码库中删除。
  Spring5.0框架自带了通用的日志封装
  
  
  
  
  • Spring5已经移除Log4jConfigListener,官方建议使用Log4j2
    
  • Spring5框架整合Log4j2
    
  第一步，引入jar包
  第二步，创建log4j2.xml配置文件

    第一步，引入JUnit5的jar包
    第二步，创建测试类，使用注解完成
    1. @ExtendWith(SpringExtension.class)@ContextConfiguration("classpath:bean1.xml")public

  Spring5框架新功能——Webflux
  
  SpringWebflux介绍
  
  
  
  
  • SpringWebflux是Spring5添加新的模块，用于web开发的，功能和SpringMVC类似的，Webflux是使用了当前一种比较流行的响应式编程而出现的框架。
    
  • 传统
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>web
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>框架，比如
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>SpringMVC，是基于
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>Servlet
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>容器的。而Webflux
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>是一种异步非阻塞的框架，异步非阻塞的框架在
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>Servlet3.1
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>以后才支持，核心是基于Reactor的相关
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>API
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>实现的。
    
  • 异步非阻塞：
    
    
    
    • 异步和同步针对调用者，调用者发送请求，如果等着对方回应之后才去做其他事情就是同步，如果发送请求之后不等着对方回应就去做其他事情就是异步。
      
    • 阻塞和非阻塞针对被调用者，被调用者收到请求之后，做完了请求任务才给出反馈，收到请求之后马上给出犯规然后再去做事情就是非阻塞。
      
    
    
  • Webflux
    <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
    </bean>特点：
    
    
    • 非阻塞式：在有限资源下，提高系统吞吐量和伸缩性，以

      <bean id="book"  p:bname="九阳神功" p:bauthor="无名氏">
      </bean>为基础实现响应式编程

    • 两个框架都可以使用注解方式，都运行在Tomet等容器中

  响应式编程（Java实现）
  
  响应式编程的介绍
  
  响应式编程是一种面向数据流和变化传播的编程范式。这意味着可以在编程语言中很方便地表达静态或动态的数据流，而相关的计算模型会自动将变化的值通过数据流进行传播。电子表格程序就是响应式编程的一个例子。单元格可以包含字面值或类似"=B1+C1"的公式，而包含公式的单元格的值会依据其他单元格的值的变化而变化。
  Java8及其之前版本

  响应式编程（Reachor实现）
  
  
  
  
  • 响应式编程操作中，Reachor是满足Reactive规范框架的
    
  • Reachor有两个核心类：Mono和Flux，这两个类实现接口Publisher，提供丰富操作符。Flux对象实现发布者，返回N个元素；Mono实现发布者，返回0或者1个元素
    
  • Flux和Mono都是数据流的发布者，使用Flux和Mono都可以发出三种数据信号：元素值、错误信号、完成信号，其中错误信号和完成信号都代表终止信号，终止信号用于告诉订阅者数据流结束了，错误信号终止数据流的同时会把错误信息传递给订阅者
    
    
  • 代码演示Flux和Mono

  • 三种信号特点
    
    
    
    • 错误信号和完成信号都是终止信号，不能共存
      
    • 如果没有发送任何元素值，而是直接发送错误或者完成信号，表示是空数据流
      
    • 如果没有错误信号，没有完成信号，表示是无限数据流
      
    
    
  • 调用just或者其他方法只是声明数据流，数据流并没有发出，只有进行订阅之后才会触发数据流，不订阅什么都不会发生的

  SpringWebflux执行流程和核心API
  
  SpringWebflux基于Reactor，默认使用容器时Netty，Netty是高性能的NIO框架，异步非阻塞的框架

    • SpringWebflux核心控制器DispatchHandler，实现接口WebHandler
      
    • 接口WebHandler有一个方法：
