How package encapsulation with Spring Modulith simplified our code
This talk explores the challenges of understanding large codebases and proposes refactoring from horizontal to vertical package structures. It demonstrates how Spring Modulith can enforce package boundaries and aid gradual adoption, offering practical refactoring tips to reduce dependencies and improve code maintainability through vertical slicing.

Have you ever felt there is too much relevant code for your current task to fit into your brain? Resulting in some StackOverflow in your head: a brain explosion.
Multiple factors contribute to this, one of them being the package structure of the code. In this talk I will explain why we wanted to refactor our package structure from horizontal (grouped by technical role like ‘controller’, ‘service’) to vertical (grouped by subject like ‘order’, ‘product’). I will show you how Spring Modulith can restrict access between packages and how you can gradually introduce it. On top of that, I will show some refactorings that we often used to break dependencies.
After this talk you will know why vertically slicing your packages might be a good idea and how you can use Spring Modulith to help you with that.
