"Bean inheritance" abstract beans in spring and bean inheritance

Declare a bean as an abstract bean by specifying abstract= "true", which can be inherited;

  
 

   
  

  
<?xml version="1.0" encoding="GBK"?>
   
  

  
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   
  

  
xmlns="http://www.springframework.org/schema/beans"
   
  

  
xsi:schemaLocation="http://www.springframework.org/schema/beans
   
  

  
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
   
  

  

   
  

  
<!-- 定义Axe实例 -->
   
  

  
<bean id="steelAxe" class="org.crazyit.app.service.impl.SteelAxe"/>
   
  

  

   
  

  
<!-- 指定abstract="true"定义抽象Bean -->
   
  

  
<bean id="personTemplate" abstract="true">
   
  

  
<property name="name" value="crazyit"/>
   
  

  
<property name="axe" ref="steelAxe"/>
   
  

  
</bean>
   
  

  

   
  

  
<!-- 通过指定parent属性指定下面Bean配置可从父Bean继承得到配置信息 -->
   
  

  
<bean id="chinese" class="org.crazyit.app.service.impl.Chinese"
   
  

  
parent="personTemplate"/>
   
  

  
<bean id="american" class="org.crazyit.app.service.impl.American"
   
  

  
parent="personTemplate"/>
   
  

  
</beans>
  
 

The above configuration is equivalent to the following

  
 

   
  

  
<?xml version="1.0" encoding="GBK"?>
   
  

  
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   
  

  
xmlns="http://www.springframework.org/schema/beans"
   
  

  
xsi:schemaLocation="http://www.springframework.org/schema/beans
   
  

  
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
   
  

  

   
  

  
<!-- 定义Axe实例 -->
   
  

  
<bean id="steelAxe" class="org.crazyit.app.service.impl.SteelAxe"/>
   
  

  

   
  

  
<!--Specify the following bean configuration from the parent bean by specifying the parent property to inherit the configuration information--

   
  

  
  span class= "tag" ><bean   id  =  Span class= "ATV" > "Chinese"   class  =   "Org.crazyit.app.service.impl.Chinese";   
   
  

  
 <property   name="name"   value="crazyit"/>  <property name="axe" ref="steelAxe"/>
   
  

  
 <bean/>
   
  

  


   
  

  
<bean id="american" class="org.crazyit.app.service.impl.American">
   
  

  
< Span class= "ATV" >   <property     Name  =   "name"    value  =   "Crazyit"  />    <property   name  =   "axe"   ref  =   "Steelaxe"  />    <bean   />  
   
  

  
</beans>
