Spring Boot FAQ: Top Questions

38. How can you use Lombok in a Spring Boot project?

Lombok is a Java library that helps reduce boilerplate code by generating common methods like getters, setters, constructors, and more at compile time.

🗺️ Steps:

Add the Lombok dependency to your pom.xml or build.gradle.
Use annotations like @Getter, @Setter, @Data, etc.

📥 Example:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Person {
  private String name;
  private int age;
}

🏆 Expected Output:

Lombok generates getters, setters, constructors, toString, etc.

🛠️ Use Cases:

Simplify domain model code.
Reduce boilerplate in DTOs and entities.
