Spring的核心原理

一、IOC容器的运行原理

[*]容器：Spring容器是整个核心的载体（如BeanFactory和ApplicationContext）像一个超级工厂负责（既Bean）的创建、管理形成一套生命周期
[*]IOC反转控制:IOC本质是一种思想，是根据依赖倒置原则(DIP)来实现的一种规则,其核心是通过对象的创建和依赖关系，将控制权从应用程序代码转移到容器,实现模块间的解耦。
[*]依赖注入（DI）:依赖注入是IOC的核心实现手段
补充：
DIP原则：高层模块不直接依赖低层模块，二者均依赖抽象（接口/抽象类）。抽象不依赖细节，细节依赖抽象。
解决痛点：
将所有的创建都交给工厂统一管理,而非开发者手动创建，让开发者将重心更倾向于业务代码上
二、Spring <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>IoC <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>容器定义 <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>XML <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>配置文件
以下是创建容器配置文件的几种方式
实现类


[*]id:表示bean在容器中的唯一标识，在获取bean时是根据id来获取
[*]class：Bean的完整类名，通过反射创建实例后纳入容器中管理
引言
以上得知bean标签的是通过class属性读取实现类，从而进行让Spring容器接管，那我们是不是也可以将自定义的工厂容器也一并交给Spring容器进行管理
业务接口如下：

自定义静态工厂如下:
public <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>class <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>StudentServiceFactory <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>{ <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean> <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean> <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean> <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>public <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>static <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>UserService <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>create(){ <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean> <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean><bean <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>id="peopleServiceFactory" <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>></bean>

为什么说工厂本身不托管，因为通过静态方法是可以通过类名直接调用属于类别，从而不需要容器托管
3.基于FactoryBean来创建受管的Bean对象
public <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>class <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService"

引言

[*]在容器底层中Bean标签的相应属性值是由Map集合保存如key保存唯一标识id，value则是存储组件实例。
[*]而不同作用域存储的Map也截然不同
单例原理解析如下：
Map <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>singleTon <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>= <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>new <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>HashMap();Object <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>object <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>= <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>clazz.getConstructor() <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>.newInstance();singleTon.put("userService", <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>object);从value的类型可知存储的是创建好的实例
原型原理解析如下：
Map <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>beanClass <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>= <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>prototypeMap.get("userService");beanClass.getConstructor().newInstance();Class是一个泛型类型，可接收任意类的 <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>Class <bean id="userService"scope="prototype"></bean><bean <bean id="userService"scope="prototype"></bean>id="studentService" <bean id="userService"scope="prototype"></bean> <bean id="userService"scope="prototype"></bean>factory-method="create"></bean>,而Map的值中存储的是按需创建类的Class,从而通过类来重新实例
