Spring(二)-生命周期 + 自动装配(xml) +自动装配(注解)

1、生命周期

**Spring容器的 bean **的生命周期；
1.1 默认生命周期

1.1.1 生命周期

•   调用构造方法，创建实例对象；
  
• set方法，给实例对象赋值；
  
• init 初始化方法 初始化对象；(手写并配置到bean上init-method="")
  
• 使用容器中的bean对象；
  
• destroy 销毁方法 销毁对象 (手写并配置到bean上destroy-method="")

1.2.2 后置处理器

• 要求：必须实现 BeanPostProcessor 接口
  
• 自定义 bean 的 后置处理器，对容器中所有的bean统一处理(生效)，
  
• 要生效的话，必须将此处理器放到容器中(配置到spring的核心配置文件中，增加处理器的实例配置);
  

注意：当前案例，只对容器中的一个实例处理；
MyBeanPostProcessor

1. public class MyBeanPostProcessor implements BeanPostProcessor {
2. <bean id="person"  autowire="byName">
3. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >

1.2.3 BeanPostProcesso

参考博客：BeanPostProcessor简介
BeanPostProcessor官方定义为工厂钩子，我们也俗称后置处理器。它允许自定义修改新的bean实例，例如检查标记接口或用代理包装它们。应用程序上下文可以在其bean定义中自动检测BeanPostProcessor bean，并将它们应用于随后创建的任何bean。

测试，报错信息：
No qualifying bean of type 'com.kgc.spring.auto.Car' available: expected single matching bean but found 2: car,carNew
总结：autowire="byType"  当有多个相同类型的bean时，无法确定要装配的 bean;
2.5 bean 配置（byName）

其他配置信息不变，设置 autowire="byName" ，根据 属性 的 名字 自动装配；

1. <bean id="person"  autowire="byName">
2. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
3. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
4.     <context:include-filter type="assignable" expression="com.kgc.spring.acnocation.bean.ToyImpl1"/>

6. </context:component-scan><property name="nickName" value="hauyu"></property>

总结：

• byType:根据类型自动装配：
  
  
  
  • 根据实体属性的  类型，到容器中，根据  bean类型  进行唯一匹配，如果可以匹配到对应类型的bean的实例，就会执行自动装配， 如果不能唯一匹配(同类型的bean有多个)，会报错；
    
  
  
• byName: 根据名称自动装配：
  
  
  
  • 根据属性的  属性名，到容器中，根据  bean的id  属性值，进行唯一匹配，如果能够成功匹配，执行自动装配， 如果匹配不到，不执行自动装配，实体属性为null;
    
  
  

3、自动装配 (注解)

3.3.1 注解的原理

默认情况下：spring自动将分层组件(@Controller,@Service,@Repository,@component)标识的类(不是接口)，自动创建实例对象放入容器中，使用bean的标识id值为 对应类名首字母小写  就相当于，帮我们手动添加了配置 :
...
3.1.2 自定义id 属性

如果不想使用默认的类名首字母小写，我们可以使用注解的value属性执行一个自定义的id值;
比如:@Service(value="自定义的id值")，注解只有value属性，可以省略value执行，简化为@Service("自定义的id值")
3.1.3  分层组件的目的

分层组件的目的，就仅仅是为了方便开发人员明确当前注解所在的类所对应的角色，在使用上，建议使用，按照官方定义的使用，防止模糊不清；在springMVC框架中@Controller有特殊含义；
3.2 配置文件

spring创建容器对象时，如果解析到 component-scan 组件扫描配置，会将base-package指定的基包(父包)及其子包所有增加了分层组件的类，自动创建实例，放进容器中；
配置文件

1. <bean id="person"  autowire="byName">
2. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
3. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
4.     <context:include-filter type="assignable" expression="com.kgc.spring.acnocation.bean.ToyImpl1"/>
5. </context:component-scan><context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
6. </context:component-scan><property name="nickName" value="hauyu"></property>
7. </bean>

3.5 自动装配

3.5.1 @Autowired

• 组件自动装配，可以实现实体属性类型的自动装配，自动到spring的容器中，根据当前属性的类型或者名称进行注入，如果容器中能匹配到，就直接将实例对象注入到当前实体属性上，无序手动指定;
  
• @Autowired自动装配原理：首先会根据byType方式，进行自动装配，
  
  
  
  • 如果不能唯一匹配（存在同类型多个实例对象），会再次尝试使用byName方式，根据当前实体属性名，到容器中进行匹配（容器中bean的id值）,如果能唯一匹配，直接执行自动装配，
    
  
  
• 默认情况下，@Autowired注解标识的实体属性，必须被装配
  
  
  
  • 如果装配失败，就直接抛出异常;
    
  • 如果不需要校验必须被装配（项目启动，如果装配失败，项目是起不来）;
    
  • 通过指定required = false，去除必须执行自动装配的校验（即便容器中找不到装配的实例，也不会抛出异常）;
    
  
  
• 如果自动装配，容器中存在多个同类型的bean对象，可以使用注解@Qualifier("容器中同类型多个bean的某个id值")，实现指定到容器中，找对应的bean实例对象，进行自动装配;
  
• 底层是如何做的：在指定要扫描的包时， 元素会自动注册一个bean的后置处理器：AutowiredAnnotationBeanPostProcessor的实例。该后置处理器可以自动装配标记了@Autowired、@Resource或@Inject注解的属性。

3.6 指定扫描 排除扫描

3.6.1 指定扫描

include-filter
指定扫描(包含扫描)：

• 只会扫描指定的类或者某类组件(使用分组扫描)，加入到容器中；
  
• 但是必须配合父标签的user-default-filter使用，默认值是true，就是全部扫描；
  
• 指定扫描，如果要生效必须改为false；
  
• 指定扫描某类组件，type="annotation"  expression="某类组件注解的全类名"；
  
• 指定扫描某个类，type="assignable"   expression="某个类的全类名"；
  

3.6.1.1 指定扫描某类组件

type="annotation"

• org.springframework.stereotype.Component
  
• org.springframework.stereotype.Repository
  
• org.springframework.stereotype.Service
  
• org.springframework.stereotype.Controller
  

1. <bean id="person"  autowire="byName">
2. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
3. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
4.     <context:include-filter type="assignable" expression="com.kgc.spring.acnocation.bean.ToyImpl1"/>
5. </context:component-scan><context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
6. </context:component-scan><property name="nickName" value="hauyu"></property>
7. </bean>

复制代码

3.6.1.2  指定扫描某个类

type="assignable"

1. <bean id="person"  autowire="byName">
2. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
3. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="false" >
4.     <context:include-filter type="assignable" expression="com.kgc.spring.acnocation.bean.ToyImpl1"/>
5. </context:component-scan><context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
6. </context:component-scan><property name="nickName" value="hauyu"></property>
7. </bean>

复制代码

3.6.2 排除扫描

exclude-filter

• 排除扫描(剔除扫描)：排除指定的类或某类组件，不加入到容器中，处理排除外的其他组件，仍然会被添加到容器中；
  
• 不需要配合父标签，use-default-filters="true" 因为，默认就是在全部扫描的基础上剔除；
  
• 排除扫描某类组件，type="annotation"  expression="某类组件注解的全类名"；
  
• 排除扫描某个类，type="assignable"   expression="某个类的全类名"；
  

3.6.2.1 排除扫描某类组件

type="annotation"

1. <context:component-scan base-package="com.kgc.spring.acnocation" use-default-filters="true" >
2. <context:component-scan base-package="com.kgc.spring.acnocation" >
3.         <context:exclude-filter type="assignable" expression="com.kgc.spring.acnocation.bean.ToyImpl1"/>
