Lombok Library practices note

My Usage:

Bean: @Builder, @NoArgsConstructor, @Setter, @Getter, @Data
Service/Component: @Slf4j, @RequiredArgsConstructor

Because I heavily use JSON in my application, I generally need a no-args constructor in the beans.

Notes:

@Builder can't work with only @NoArgsConstructor; it also requires @AllArgsConstructor.
@SuperBuilder works only with @NoArgsConstructor and without @AllArgsConstructor.
Using @Builder on a superclass and @SuperBuilder on the subclass works, but only the superclass instance is built.

Best Practices:

Prefer @SuperBuilder over @Builder when working with inheritance.
