==============================
What is a REST Repository ?
==============================

=> A REST Repository is a feature provided by Spring Data REST module.

=> Without writing REST Controller we can perform REST API based crud operations using REST Repository concept.

Note: It will expose our JPA Repository as a REST Controller.

		REST Repository = REST Controller + Jpa Repository


=> Instead of manually writing REST controllers, you define a repository interface, and Spring Data REST will expose standard REST endpoints for you.


================================
Application Development Process	
===============================

Step-1 : Create Boot app with below dependencies

		a) rest repositories

		b) data-jpa-starter

		c) mysql-connector

		d) devtools

		e) lombok	

Step-2 : Configure data source properties in application.yml file

Step-3 : Create Entity class and Repository interface

```
@Entity
@Data
public class Student {

	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	private Long id;
	private String name;
	private String email;
}

```

@RepositoryRestResource
public interface StudentRepo extends JpaRepository<Student, Long> {

}

```

Note: Represent our JPA Repository as REST Repository using @RepositoryRestResource.

Step-4 : Start the application and Test REST Endpoints using POSTMAN.		

=================================================================

GET ALL Students : GET :: http://localhost:8080/students

Create Student : POST :: http://localhost:8080/students

Update Student : PUT :: http://localhost:8080/students/{id}

Delete Student : DELETE :: http://localhost:8080/students/{id}

===================================================================

{
    "name" : "B. Ashok",
    "email" : "ashok@gmail.com"
}

==================================================================

=> No need to write boilerplate REST controller code.

=> Rapid API development.


Note: When we have requirement to implement business logics, validation logics, email sending, encryption, decryption then it is not recommended.
