Java Lombok Usage Guide

Lombok is a Java library that automates common Java development tasks such as generating getter and setter methods, constructors, equals and hashcode methods using annotations. It helps reduce code redundancy and improve development efficiency.

Here are some commonly used annotations in Lombok:

1. @Getter and @Setter: Generate corresponding getter and setter methods based on fields.
2. @ToString: Creates a toString method.
3. @EqualsAndHashCode: Generates equals and hashCode methods.
4. @NoArgsConstructor: Generate a constructor with no parameters.
5. @AllArgsConstructor: generates a constructor that contains all fields.
6. @Data is equivalent to using the annotations @Getter, @Setter, @ToString, @EqualsAndHashCode, and @NoArgsConstructor together.
7. @Builder: Generate constructor for builder pattern.
8. @SLF4J: Create an Slf4j log object.

When using Lombok, you need to add the necessary dependencies in the project’s build configuration file and ensure that Lombok support is enabled in the IDE. In classes that use Lombok annotations, the IDE will automatically generate the corresponding code based on the annotations, eliminating the need to manually write it.
