What is the fundamental difference between a POJO, a DTO, and an Entity in Java?

When should I use a POJO, a DTO, or an Entity in a Spring Boot application?

Why are DTOs important for designing REST APIs in Spring Boot?

What are the disadvantages of not using DTOs in the API layer?

How do Entities relate to database tables in a JPA/Hibernate context?

Can an Entity have business logic, and if not, where should it reside?

What problems does manual object mapping create in large Java applications?

What is MapStruct, and how does it solve the manual mapping problem?

How does MapStruct work internally (e.g., compile-time code generation)?

What are the key benefits of using MapStruct over other mapping libraries or manual mapping?

How do you set up MapStruct in a Spring Boot project (e.g., Maven/Gradle dependencies)?

How do you define a basic MapStruct mapper interface?

How can MapStruct handle fields with different names between source and target objects?

Can MapStruct be used to map between multiple source objects to a single target?

How do you map calculated fields or perform custom logic during mapping with MapStruct?

When should I convert an Entity to a DTO, and vice-versa, in a typical request/response flow?

How does MapStruct help in decoupling the database schema from the API contract?

Can MapStruct handle nested object mappings (e.g., an object containing another object)?

How do you integrate MapStruct with Spring's dependency injection (e.g., using @Mapper(componentModel = "spring"))?
