Spring Bean Definition Inheritance Example

By | June 22, 2021

In this post, We will learn about the Spring Bean Definition Inheritance Example using a Demo Project.

A child bean definition can inherit configuration data from a parent definition. The child definition can also override some properties or add others as needed.

Spring Framework Bean’s definition of inheritance has nothing to do with Java class inheritance but the inheritance concept is almost similar. We can define a parent bean definition as a template and other child Spring beans can inherit the required configuration from the parent bean.




When We use XML-based configuration then a child bean definition can refer to the parent attribute, specifying the parent bean as the value of this attribute.

We can usually create a Bean definition template and that can be used by other child bean definitions without putting much effort. While defining a Bean Definition Template, We should not specify the class attribute and should specify an abstract attribute with a value of true as shown in the following code snippet −


If you run ClientTest.java as Java Application then it will give the below output: 

Employee [id=1001, name=KK, gender=Male, departmentName=IT, salary=80000.0]
