Lombok is a popular Java library that helps reduce boilerplate code in your projects by automatically generating common code, such as getters, setters, constructors, and more. When combined with Spring Boot, Lombok can make your code more concise and readable. In this tutorial, we’ll explore various Lombok annotations and how they can be used in a Spring Boot application.


Make sure you have the following installed:

  1. Java Development Kit (JDK) – preferably JDK 8 or later.
  2. Spring Boot – you can use the Spring Initializer or your preferred method to set up a Spring Boot project.

1. Adding Lombok to your project

Add the Lombok dependency to your project’s build file. If you are using Maven, add the following dependency to your pom.xml:

2. Basic Lombok Annotations


The @Data annotation is a convenient shortcut annotation that bundles the functionalities of @ToString, @EqualsAndHashCode, @Getter, and @Setter. It is commonly used on classes to generate boilerplate code for these methods.

@Getter and @Setter

These annotations generate getter and setter methods for your class variables.

@NoArgsConstructor, @RequiredArgsConstructor, and @AllArgsConstructor

These annotations generate no-argument, required-argument, and all-argument constructors, respectively.

3. Lombok Annotations in Spring Boot


The @Slf4j annotation generates a logger field for your class.


The @Builder annotation creates a builder class for your class, making it easy to create instances with a fluent API.






Lombok provides a variety of annotations that can significantly reduce boilerplate code in your Spring Boot projects. By incorporating Lombok into your development process, you can write more concise and readable code. Experiment with these annotations in your Spring Boot application to see how they can enhance your development experience.
