Spring data rest:

##### Spring Data REST makes it easy to expose microservices. 
##### Spring Data REST builds on top of Spring Data repositories and automatically exports those as REST resources.

#### So how does Spring Data Rest work?

* At application startup, Spring Data Rest finds all of the spring data repositories

* Then, Spring Data Rest creates an endpoint that matches the entity name

* Next, Spring Data Rest appends an S to the entity name in the endpoint

* Lastly, Spring Data Rest exposes CRUD (Create, Read, Update, and Delete) operations as RESTful APIs over HTTP

* There is no need to create a controller or service layer!

Item.java:

@Entity

public class Item{
@Id
@GenereatedValue(strategy = GenerateType.AUTO)

Private Long id;
Private String name
Private Long description;

}

-> Item Repo:

public interface ItemRepository extends CrudReository<Item,Long> 
{

}

-> applicaiton.properties:

logging.level.org.springframework:DEBUG

# H2
spring.h2.console.enabled=true

To Test:

For a @SpringBootApplication to be discovery-aware, all that's needed is the Spring Discovery Client (i.e., spring-cloud-starter-netflix-eureka-client dependency) in the classpath. The next step is to annotate the main Spring application class with the @EnableEurekaClient annotation. @EnableEurekaClient is optional if the spring-cloud-starter-netflix-eureka-client dependency is on the classpath.
