In Spring, the inheritance is supported in bean configuration for a bean to share common values, properties or configurations.

A child bean or inherited bean can inherit its parent bean configurations, properties and some attributes. In additional, the child beans are allow to override the inherited value.

例子如下：

public class Customer { 	private int type;	private String action;	private String Country; 	//... }

　　

　　

public class App {    public static void main( String[] args )    {    	ApplicationContext context = 			new ClassPathXmlApplicationContext("SpringBeans.xml");     	Customer cust = (Customer)context.getBean("CustomerBean");    	System.out.println(cust);     }}

　　运行结果为：Customer [type=1, action=buy, Country=Malaysia]

In above example, the ‘BaseCustomerMalaysia’ is still able to instantiate, for example,

 

Customer cust = (Customer)context.getBean("BaseCustomerMalaysia");

　　类似于java的抽象类，我们可以有：(注意abstract="true")

　　现在当你运行：

Customer cust = (Customer)context.getBean("BaseCustomerMalaysia");

　　将会出现：

org.springframework.beans.factory.BeanIsAbstractException: 	Error creating bean with name 'BaseCustomerMalaysia': 	Bean definition is abstract

Pure Inheritance Template

　　也可以重写值：
