3)spring中的设计模式
学习spring的, 先了解下spring中紧张的设计模式:
1. 工厂模式
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 1.简朴工厂
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 简朴工厂模式是一种创建型设计模式，用于根据给定的范例实例化不同的类
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 比方:不同的动物范例创建对应的动物实例。

<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 饿汉式单例模式是一种创建型设计模式，它在类加载时就创建了对象实例，并确保只有一个实例存在.

}饿汉式单例模式在类加载时就创建了实例，这意味着即使您从未使用过该实例，它也会占用内存。这可能导致资源浪费，特殊是在实例创建成本较高的情况下.
2.懒汉式(不可用,线程不安全)

<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 懒汉式单例模式是一种创建型设计模式，它在第一次哀求实例时才创建唯一的实例，并确保整个应用程序中仅存在一个实例.

<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 首先，我们进行第一次检查：如果instance为空，阐明实例尚未创建，此时需要获取Singleton.class的锁。当线程成功得到锁后，进行第二次检查：确保在其他线程得到锁之前实例仍未被创建。如果instance仍然为空，则创建新的实例；否则，直接返回已创建的实例。

<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 此实现在多线程情况中是线程安全的，并且相对于每次都获取锁的懒汉式单例模式具有更好的性能
5.静态内部类(推荐使用)
public class Singleton {
// 将构造方法设为私有，防止外部创建新实例

<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 当Singleton类加载时, 由于静态内部类在外部内加载时并不会加载, 而时在静态内部内调用时才加载, 所以该方法并不会像饿汉式那样浪费资源, 同时Java规范保证了静态初始化是线程安全的，因此在类加载时会创建唯一的实例, 所以次方法比力推荐;
6.枚举(推荐使用)

}使用枚举实现单例模式是一种简洁且安全的方法。在Java中，枚举范例可以确保线程安全和实例唯一性;
3.代理模式
代理模式是一种布局型设计模式，其目的是通过代理来控制对实际对象的访问。代理通常与实际对象具有相同的接口，并将哀求转发给实际对象，可能会在转发之前或之后执行其他操作;

}在实际应用中，代理模式可以被用于实现许多功能，比方安全性检查、日志记录、缓存和远程访问等.
4)了解Spring大家族
Spring发展到本日已经形成了一种开发的生态圈，Spring提供了若干个项目，每个项目用于完成特定的功能;官网: Spring | Home
1.spring framework
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 也就是我们经常说的spring框架，紧张分为IOC和AOP两大块;
2.spring boot

5)spring framework构成
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> spring框架分为两大块, IOC和AOP;
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> spring框架包含一下几大模块:
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230217515-1906488285.png
1、 Core Container(焦点容器)
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Beans模块：提供了BeanFactory，是工厂模式的经典实现，Spring将管理对象称为Bean。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Core焦点模块：提供了Spring框架的基本构成部门，包括IoC和DI功能。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Context上下文模块：创建在Core和Beans模块的基础之上，它是访问定义和配置的任何对象的媒介。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> SpEL模块：它提供了Spring Expression Language支持，是运行时查询和操作对象图的强盛的表达式语言
2、Data Access/Integration(数据访问/集成)
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> JDBC模块：提供了一个JDBC的抽象层，大幅度地减少了在开发过程中对数据库操作的编码。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> ORM模块：对流行的对象关系映射API，包括JPA、JDO和Hibernate提供了集成层支持。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> OXM模块：提供了一个支持对象/ XML映射的抽象层实现，如JAXB、Castor、XMLBeans、JiBX和XStream。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> JMS 模块：指 Java 消息通报服务，包含使用和产生信息的特性，自 4.1 版本后支持与Spring-message模块的集成。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Transactions事务模块：支持对实现特殊接口以及所有POJO类的编程和声明式的事务管理。
3、 Web
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> WebSocket模块：Spring 4.0以后新增的模块，它提供了WebSocket 和SockJS的实现，以及对STOMP的支持。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Servlet模块：也称为Spring-webmvc模块，包含了Spring的模型—视图—控制器(MVC)和REST Web Services实现的Web应用程序。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Web模块：提供了基本的Web开发集成特性，比方：多文件上传功能、使用Servlet监听器来初始化IoC容器以及Web应用上下文。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Portlet模块：提供了在Portlet情况中使用MVC实现，雷同Servlet模块的功能。
4、 其他模块
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> AOP 模块：提供了面向切面编程实现，允许定义方法拦截器和切入点，将代码按照功能进行分离，以降低耦合性。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Aspects 模块：提供了与AspectJ的集成功能，AspectJ是一个功能强盛且成熟的面向切面编程(AOP)框架。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Instrumentation 模块：提供了类工具的支持和类加载器的实现，可以在特定的应用服务器中使用。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Messaging模块：Spring 4.0以后新增的模块，它提供了对消息通报体系布局和协议的支持。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Test模块：提供了对单元测试和集成测试的支持
2 IoC和DI
1)IoC介绍和使用
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> IoC（Inversion of Control）控制反转, 它将对象之间的依赖关系与对象本身的创建和管理分脱离来。这有助于降低程序中各个组件之间的耦合度，并提高代码可维护性、可测试性以及扩展性。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 在Spring IoC容器中，对象的生命周期由容器进行管理，而不是由对象自己管理。IoC容器负责实例化、配置和装配Bean，然后将这些Bean注入到需要的组件中。使用IoC可以使您专注于业务逻辑的实现，而不必关心底层的对象创建和依赖解析工作。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Spring IoC容器紧张包括两种范例：
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 1.BeanFactory：BeanFactory是一个简朴的容器，它负责实例化、定位、配置应用程序中的对象，并解决它们之间的依赖关系。XmlBeanFactory是最常用的BeanFactory实现。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 2.ApplicationContext：ApplicationContext是BeanFactory的子接口，它为应用程序提供了更多的企业级特性，如消息资源处理、事件发布、声明式事务处理等。通常，我们会使用ApplicationContext作为Spring IoC容器，常见的实现有ClassPathXmlApplicationContext、FileSystemXmlApplicationContext等

bean的生命周期
[*]实例化：Spring根据配置文件或注解定义创建Bean实例。
[*]属性添补：Spring通过依赖注入将指定的属性值和引用设置到Bean的属性中，这可以是基于构造方法、setter方法或字段的注入。
[*]容器回调（Aware接口）：如果Bean实现了某些特定的Aware接口（如BeanNameAware、BeanFactoryAware等），Spring会自动调用相应的回调方法，将容器相关的信息通报给Bean。
[*]BeanPostProcessor前置处理：Spring会调用已注册的所有BeanPostProcessor接口实现类的postProcessBeforeInitialization方法，允许您进行自定义处理，比方修改Bean属性或改变Bean引用。
[*]初始化：当Bean的所有属性都设置好后，Spring会检查Bean是否实现了InitializingBean接口，如果实现了该接口，Spring会调用afterPropertiesSet()方法。别的，如果Bean定义中包含init-method属性（XML配置）或@PostConstruct注解（注解配置），也会执行对应的初始化方法。
[*]BeanPostProcessor后置处理：Spring会调用已注册的所有BeanPostProcessor接口实现类的postProcessAfterInitialization方法，同样允许您进行自定义处理。
[*]Bean准备停当：至此，Bean已经准备好了，可以被应用程序使用。
[*]销毁：当容器关闭时，Spring会检查Bean是否实现了DisposableBean接口，如果实现了该接口，Spring会调用destroy()方法。别的，如果Bean定义中包含destroy-method属性（XML配置）或@PreDestroy注解（注解配置），也会执行对应的销毁方法。
注意：在整个生命周期中，BeanPostProcessor前置/后置处理和Aware接口回调等特性可以通过编程方式自定义，以满足具体需求。
2)DI的介绍和使用
依赖注入（Dependency Injection，DI）是Spring框架的焦点概念之一。它是一种将组件之间的依赖关系从组件内部移除的设计模式，使得组件之间的耦合度降低，代码更加机动和可维护.
在Spring框架中，DI通过控制反转（Inversion of Control，IoC）容器实现。IoC容器负责管理应用程序中的对象（称为Bean）以及它们之间的依赖关系。简朴来说，DI允许我们将对象的创建和配置委托给IoC容器，并在需要时将这些对象注入其它对象.
Spring提供了以下几种紧张的依赖注入方式：
[*]基于构造函数的注入：通过构造函数将依赖项通报给需要它们的类。在XML配置中，使用元素实现；而在基于注解的配置中，可以在构造函数上添加@Autowired注解。
[*]基于Setter方法的注入：通过调用setter方法将依赖项通报给需要它们的类。在XML配置中，使用元素实现；而在基于注解的配置中，可以在setter方法上添加@Autowired注解。
[*]基于字段的注入：直接向类的字段注入依赖项，而无需使用构造函数或setter方法。在基于注解的配置中，可以在字段上添加@Autowired注解。

<aop:aspectj-autoproxy></aop:aspectj-autoproxy> Spring AOP（Aspect-Oriented Programming，面向切面编程）是Spring框架的一个紧张特性，它允许将与业务逻辑无关的横切关注点（如日志记录、安全检查、事务管理等）从应用程序代码中分离出来。这有助于提高代码的模块化程度，使得应用程序更加易于维护和扩展。
<bean ></bean>
<beanid="myLogger"></bean>
<aop:aspectj-autoproxy></aop:aspectj-autoproxy> 在Spring AOP中，紧张涉及以下几个焦点概念：
[*]切面（Aspect）：封装了横切关注点的模块化代码，通常包含一个或多个通知（Advice）以及切入点（Pointcut）的定义。
[*]通知（Advice）：切面在特定连接点执行的操作。根据执行机遇不同，通知可以分为前置通知（Before）、后置通知（After）、返回通知（After-returning）、异常通知（After-throwing）和围绕通知（Around）。
[*]切入点（Pointcut）：描述了通知应该织入的一系列连接点。切入点通过类和方法签名的模式匹配定义，比方匹配特定包下所有类的所有方法。
[*]连接点（Join point）：程序执行过程中可以插入切面操作的点，比方方法调用、构造函数调用、字段赋值等。Spring AOP仅支持方法执行连接点。
[*]引入（Introduction）：允许为现有类添加新方法或属性的一种方式。
[*]织入（Weaving）：将切面与目标对象组合在一起，创建代理对象的过程。织入可以在编译时、类加载时或运行时完成。Spring AOP默认使用运行时织入。

调用methdoA，如果methodB发生异常，触发事务回滚，也会methodA中的也会回滚
2.SUPPORTS
支持当前事务，如果当前存在事务，就加入该事务，如果当前不存在事务，就以非事务执行。
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230518799-2117519741.png
如果调用methodA，再调用methodB，MehtodB会加入到MethodA的开启的当前事务中。如果直接调用methodB，当前没有事务，就以非事务执行。3.MNDATORY
支持当前事务，如果当前存在事务，就加入该事务，如果当前不存在事务，就抛出异常。
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230550322-436123342.png
如果调用methodA，再调用methodB，MehtodB会加入到MethodA的开启的当前事务中。如果直接调用methodB，当前没有事务，就会抛出异常。4.REQUIRES_NEW
创建新事务，无论当前存不存在事务，都创建新事务。
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230604453-1920248180.png
调用methodA，会先开启事务1，执行A的something pre的代码。再调用methodB，methdoB会开启一个事务2，再执行自身的代码。最后在执行methodA的something post。如果method发生异常回滚，只是methodB中的代码回滚，不影响methodA中的代码。如果methodA发生异常回滚，只回滚methodA中的代码，不影响methodB中的代码。5.NOT_SUPPORTED
以非事务方式执行操作，如果当前存在事务，就把当前事务挂起。
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230621168-256856683.png
调用methodA，再调用methodB，methodA开启的事务会被挂起，即在methodB中不齐作用，相称于没有事务，methodB内部抛出异常不会回滚。methodA内的代码发生异常会回滚。直接调用methodB，不会开启事务。
6.NEVER
以非事务方式执行操作，如果当前存在事务，则抛出异常。
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230632772-299032614.png
7.NESTED
如果当前存在事务，则在嵌套事务内执行。如果当前没有事务，则按REQUIRED属性执行。
https://img2024.cnblogs.com/blog/3237288/202406/3237288-20240612230709950-591440132.png
调用methodA，开启一个事务，执行something pre的代码，设置回滚点savepoint,再调用methodB的代码，如果methodB里抛出异常，此时回滚到之前的saveponint。再然后执行methodA里的something post的代码，末了提交大概回滚事务。嵌套事务，外层的事务如果回滚，会导致内层的事务也回滚；但是内层的事务如果回滚，仅仅是回滚自己的代码，不影响外层的事务的代码。
4)事务的隔离级别
1) 读未提交(脏读)(不加任何锁)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans> 当一个事务开启后, 修改了数据, 但是未提交事务之前,另外一个事务来读取数据,可以读到未提交的数据;
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans>由于读的数据是未提交的, 那么万一事务回滚, 数据就读到的是错的;会产生脏数据;
2)读提交(不可重复读)(写锁(部门行))
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans>如果是一个读事务(线程)，则允许其他事务读写，如果是写事务将会禁止其他事务访问该行数据，该隔离级别避免了脏读，但是可能出现不可重复读。事务A事先读取了数据，事务B紧接着更新了数据，并提交了事务，而事务A再次读取该数据时，数据已经发生了改变
3)可重复读(读写锁(部门行))
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans>可重复读取是指在一个事务内，多次读同一个数据，在这个事务还没竣事时，其他事务不能访问该数据(包括了读写)，这样就可以在同一个事务内两次读到的数据是一样的，因此称为是可重复读隔离级别;
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
<beanscope="prototype">
<property name="sid" value="1001"></property>
<property name="sname" value="张三"></property>
<property name="gender" value="男"></property>
</bean> http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="student" ></bean>
</beans>读取数据的事务将会禁止写事务，写事务则禁止任何其他事务(包括了读写)，这样避免了不可重复读和脏读，但是偶然可能会出现幻读。
4)串行话(读写锁(表))
这是最高的隔离级别，它通过欺压事务排序，使之不可能相互辩论，从而解决幻读问题。简言之，它是在每个读的数据行上加上锁。在这个级别，可能导致大量的超时征象和锁竞争;
事务隔离级别脏读不可重复读幻读读未提交<?xml version="1.0" encoding="UTF-8"?>

[*]@Component：将类标记为Spring管理的Bean。@Service、@Repository和@Controller都是特定范例的@Component注解，分别表现服务层、数据访问层和控制层组件。
[*]@Autowired：用于自动装配Bean之间的依赖关系。可以用于构造函数、setter方法或字段上。从Spring 4.3开始，如果只有一个构造函数，可以省略@Autowired。
[*]@Qualifier：当有多个相同范例的Bean时，使用@Qualifier指定特定的Bean进行注入。通常与@Autowired一起使用。
[*]@Value：用于向Bean的属性注入基本范例或String范例的值，支持SpEL表达式。
[*]@Scope：定义Bean的作用域，如singleton（默认）、prototype、request、session和global session。
[*]@PostConstruct：标记一个方法作为初始化方法，该方法会在Bean实例化并设置完所有属性后调用。
[*]@PreDestroy：标记一个方法作为销毁方法，在容器关闭前调用。
[*]@Configuration：将类标记为Spring Java配置类，用于定义和注册Bean。
[*]@Bean：用于@Configuration类中的方法上，声明一个Bean。方法返回的对象将由Spring容器管理。
[*]@ComponentScan：用于Java配置类上，声明启用组件扫描。可以指定扫描的基础包和过滤条件。
