Lombok
Lombok is a Java library that uses compile-time annotations to generate boilerplate code such as accessors, constructors, and object methods.
Spring in Action, Sixth Edition
Lombok is a Java library that generates boilerplate code, such as accessors, constructors, and object methods, through annotations during compilation.
- How it is used
- Keeps Java domain objects concise by generating routine methods through annotations.
- How deep it goes
- Explains @Data behavior and Maven setup, including compile-time use and runtime exclusion, without covering Lombok internals.
- Examples
- Uses Ingredient, Taco, and TacoOrder classes to demonstrate generated methods alongside custom domain behavior.
- What you can do after
- Apply Lombok with @Data and configure its Maven dependency for compile-time generation.
The Art of Code
Lombok is a Java library that generates boilerplate source constructs through annotations during compilation.
- How it is used
- Reduces Java data-class boilerplate and supplies readable object construction through a generated Builder pattern.
- How deep it goes
- Demonstrates the builder benefit and quantifies manual boilerplate, but stops short of broader annotation behavior or compilation internals.
- Examples
- Uses Person constructors, a verbose DTO, and a named Person.builder() call to contrast fragile and readable instantiation.
- What you can do after
- Apply Lombok's @Builder annotation to generate a readable builder for a Java data class.
