Question

I am writing RESTful services using spring and hibernate. I read many resource in internet, but they did not clarify my doubts. Please explain me in details what are DAO

Answer 1

DTO is the @Entity annotation in Spring
DAO is the @Repository annotation in Spring (With Spring Boot JPA you just need to implement the interface now you don't need the annotations)
Service is the @Service annotation in Spring
