This advanced trick can significantly improve your application’s performance and flexibility by only loading the beans you need based on specific conditions. Let’s dive into how you can implement this in your Spring Boot projects.

The Problem

In a typical Spring Boot application, all beans defined in the context are created and initialized at startup. While this is convenient, it can lead to unnecessary resource consumption, especially in large applications with many beans. This is where conditional bean loading comes into play.

The Solution: @Conditional Annotation

Spring provides the @Conditional annotation, which allows beans to be created conditionally based on certain criteria. This can be particularly useful for enabling or disabling features in different environments (e.g., development, testing, production) or based on the presence of certain properties or classes.

Example: Conditional Bean Loading

Let’s create a simple example to demonstrate conditional bean loading based on a…
