Lombok

What is Lombok?

: A library that allows you to easily generate boilerplate code such as Constructors, Getters/Setters, toString(), etc. through annotations when creating Model Objects like DTOs, VOs, Entities in Java

Of course, you can easily generate them using the auto-generation feature of IDEs like Eclipse, but if a variable name changes, you have to update the corresponding functions like getters/setters as well, which is inconvenient

-> Lombok annotations solve this inconvenience
