Annotation based Configuration in Spring Framework Example

By | June 17, 2021

In this post, We will learn about Annotation-based Configuration in Spring Framework with an Example

In Spring Framework,  We can use an annotation-based configuration instead of using XML config for defining the beans wiring, We have an option to move the beans configuration into component class. This can be done by using annotations on the component class, method, or field declaration. One thing you should keep in mind that before performing XML injection annotation injection is performed so the latter one(annotation based) will override the former configuration(XML configuration).

In Spring Framework annotation wiring is not enabled by default so We need to enable it before we can use the Spring annotation-based wiring in the Spring Configuration file.



Consider the following configuration file in case we want to use any annotation in our Spring application then we need to enable it using the following XML tags

Once We add



<context:component-scan base-package=”com.kkhindigyan.model”></context:component-scan>

in our XML config afterward, We can start annotating our code to indicate that Spring should automatically wire values into properties, methods, and constructors.


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