Introduction

In the world of software development, modularization is akin to the Holy Grail. It enables us to keep our codebase clean, maintainable, and most importantly, scalable. In the Java ecosystem, Spring Framework provides a collection of features that make modular development a breeze. Two annotations in particular, @Import and @ImportResource, are power tools that facilitate this. In this post, we will dive into how these annotations work and explore how to leverage them for building modular applications in Spring.

Introduction to Modular Programming

Modular programming is not just a technique but rather a philosophy that developers adopt to create organized, efficient, and maintainable code. The idea of modularization can be traced back to the early days of computing when programs started becoming increasingly complex, demanding a structured approach for better management. This complexity was the driving force behind the shift towards modular programming, and the concept has evolved significantly over the years. Today, modular programming is not merely a “good to have” feature, but it’s often considered essential, especially in enterprise-level applications.
