What is ModelMapper map?

Next, we can create a @Bean factory method to create ModelMapper instance. This way, the model mapper instance will be available for injection on the application level.
Why do we need DTO in spring boot?
It is basically used to pass data with multiple attributes in one shot from client to server, to avoid multiple calls to a remote server. Another advantage of using DTOs on RESTful APIs written in Java (and on Spring Boot), is that they can help to hide implementation details of domain objects (JPA entities).
Can we Autowire ModelMapper?
When we use the starter, we just add a Gradle dependency and then autowire the ModelMapper instance in our controllers. @Controller public class TaskController { @Autowired private TaskRepository taskRepository; @Autowired private ModelMapper modelMapper; }
What is Dozer in Java?
