lombok-patterns

Reduce Java boilerplate by applying Lombok annotations like @Getter, @Setter, and @Data to auto-generate standard methods at compile time. This eliminates repetitive code for getters, setters, toString, equals, and hashCode, letting you focus on business logic.

Create immutable objects in Java using Lombok annotations like @Value, @With, and @Builder. These annotations automatically generate immutable construction patterns and safe object modification methods, ensuring robust domain modeling without manual boilerplate.

For simple DTOs in Spring Boot, prefer Java Records for native immutability and simplicity. Use Lombok @Data or @Builder for complex domain models and entities requiring mutable fields, inheritance, or flexible construction patterns.

Lombok works with Java 21 and Spring Boot JPA entities to generate getters, setters, and equals methods. It is compatible with Java 21+ and effectively optimizes entity design and DTO creation while considering modern Java features.

Avoid using Lombok @Data in Java domain models when you need strict immutability or when dealing with JPA entities, as it generates mutable setters and can cause equals/hashCode issues with lazy-loaded relationships. Prefer @Value or @Getter/@Setter.

Build complex Java objects without long constructors by applying the Lombok @Builder annotation. It auto-generates a fluent builder API, allowing flexible and readable object construction while eliminating boilerplate code.
