Architecture of Spring Data REST
The Spring Data REST architecture diagram you sent shows the following components:
- Spring Data REST: Spring Data REST is a framework that makes it easy to build hypermedia-driven REST web services on top of Spring Data repositories.
- DAO [Repository]: The DAO layer is responsible for interacting with the underlying data store. It is implemented using Spring Data repositories.
- Database: The database is the underlying data store that Spring Data REST uses to store and retrieve data.
- Postman: Postman is a tool that can be used to send and receive HTTP requests. It is used in the diagram to show how to interact with the Spring Data REST API.
Architecture of Spring Data REST
Spring Data REST architecture works as follows:
- A client sends an HTTP request to the Spring Data REST server.
- The Spring Data REST server receives the HTTP request and routes it to the appropriate repository.
- The repository interacts with the underlying data store to perform the requested operation.
- The repository returns the results of the operation to the Spring Data REST server.
- The Spring Data REST server returns the results of the operation to the client.
What is Spring Data REST?
Spring Data REST is a framework that exposes Spring Data repositories as RESTful endpoints. It allows you to create REST APIs for your data without having to write any controller code. Under the hood, Spring Data REST uses Spring Data repositories to access and manage data. So you first need to define Spring Data repositories for your entities. These repositories extend interfaces like CrudRepository. To use Spring Data REST, you simply need to create Spring Data repositories for your domain model entities. Spring Data REST will then automatically expose these entities as REST resources. You can also customize the exposed resources using annotations and configuration options
