We’ll prefer to load such beans on a need basis. We can achieve this using the Spring @Lazy annotation. In this tutorial, we’ll learn how to use @Lazy annotation to lazily load our ...

This part of the series will show how to verify our applications with code-level as well as system-level integration tests.
