7. Let's start!
What is Spring Data REST?

8. Official information you can find, for
example, this here:
1. https://spring.io/projects/spring-data-rest - introduction...
2. https://docs.spring.io/spring-data/rest/docs/current/referen
ce/html/ - ~70 pages.

10. Microservice application without Spring
Data REST:
Services:
- logic for all
endpoints.
DBs:
- the amount
depends on
business
logic.
Endpoints:
- CRUD
for all
DB
(more or
less).

11. Microservice application with Spring
Data REST:
DBs:
- the amount
depends on
business
logic.
Interfaces:
- one for
each table.

12. All works without any endpoints and
services:
Endpoints:
- CRUD for all
DB (more or
less).
Services:
- logic for all
endpoints.
DBs:
- the amount
depends on
business
logic.

13. Result:
● Less code;
● More possibilities.

16. {
"_links" : {
"users" : {
"href" : "http://localhost:8080/users{?page,size,sort}",
"templated" : true
},
"profile" : {
"href" : "http://localhost:8080/profile"
}
}
}

17. We investigate our links:
"_embedded" : {
“tableName” : [
{ JSON },
{ JSON }, ...
]
},

18. Important remark:
Spring Data REST endpoints do not touch any olds endpoints
