Spring Inheritance - Annotation

First you make your abstract configuration, which is achieved by not marking it as @Configuration, like this:

// notice there is no annotation here public class ParentConfig { @Bean public ParentBean parentBean() { return new ParentBean(); } } 

An then you extend it, like this:

@Configuration public class ChildConfig extends ParentConfig { @Bean public ChildBean childBean() { return new ChildBean(); } } 

The result will be exactly the same as if you did this:

@Configuration public class FullConfig { @Bean public ParentBean parentBean() { return new ParentBean(); } @Bean public ChildBean childBean() { return new ChildBean(); } } 

Edit: answer to the follow-up question in the comment.

If Spring picks up both classes, parent and child, there will be problems with duplicated beans, so you cannot extend it directly. Even if you override methods, the beans from the super-class will also be instantiated by the ParentConfig.

Since your parent class is already compiled, you have 2 options:

1. Talk to the author of the parent class and kindly ask him to change it.

2. Change the @ComponentScan packages.

To clarify on solution 2:

If the parent class is in the package com.parent.ParentConfig and the child class is the package com.child.ChildConfig, you can configure the component scanning so that only classes under com.child get picked up.

You can specify the component scanning packages using the @ComponentScan("com.child") annotation on your main configuration file (think application class).
