Слайд 3What is HATEOAS?
HATEOAS is a concept of application architecture. It defines

the way in which application clients interact with the server, by navigating hypermedia links they find inside resource models returned by the server.
A core principle of HATEOAS is that resources should be discoverable through the publication of links that point to the available resources.

Слайд 4What is HAL?
HAL = Hypertext Application Language.
HAL is a generic media

type with which Web APIs can be developed and exposed as series of links.
MediaType = "application/hal+json"

Слайд 5What is HAL?
GET /orders/523 HTTP/1.1 Host: example.org Accept: application/hal+json

HTTP/1.1 200 OK Content-Type: application/hal+json { "_embedded" : { "transactions" : [ { ... } ] }, "_links" : { "first" : { "href" : "http://localhost:8080/api/transactions?page=0&size=20" }, …
}, "page" : { "size" : 20, "totalElements" : 26, "totalPages" : 2, "number" : 0 } }

@Bean

@Entity
public class User {

Слайд 12How to access repository?
The path is derived from the uncapitalized, pluralized,

simple class name of the domain class being managed.

User -> …/users
…/users/3

Слайд 13GET request
…/users // find all users using

default pagination. Returns first page
…/users?page=1 // find all users using default pagination. Returns second page
…/users?size=2 // find all users using pagination by 2. returns first page.

Слайд 14POST request
…/users

body:
{
“username” : “test”,
“age” : “1”
}

Слайд 15PUT request
…/users/1

body:
{
“username” : “test”,
“age” : “1”
}

Слайд 16DELETE request
…/users/1

Слайд 17Custom database query
@RepositoryRestResource
public interface UserRepository extends JpaRepository {
Collection findByAge(@Param(“age”) int

age);
}

Слайд 18Custom database query call
.../users/search/findByAge?age=10
