Study Notes
Spring Data REST
- Spring Data REST scans your project for JpaRepository.
- It creates REST API endpoints based on entity type.
- The endpoints are pluralized with a lowercase first character and an "s" added to the entity name, for example
/employees
.
Spring Data REST in Spring Boot
- Spring Data REST eliminates boilerplate code for REST API endpoints.
- With Spring Data REST, you don't have to code your REST API implementation.
- It creates basic CRUD operations, like GET, POST, PUT, and DELETE, for free.
- Spring Data REST uses existing JpaRepository information.
- The API is exposed on the server.
API Design Process
- The API design requires understanding API needs.
- The primary resource/entity ("employee" in the example) is identified.
- Identify a suitable name (e.g.,
/api/employees
). - HTTP methods (e.g. GET, PUT, POST, DELETE) and URLs are used for CRUD operations.
Adding Spring Data REST to a Project
- Add the
spring-boot-starter-data-rest
dependency to your project's Maven pom.xml file.
Spring Data REST Features
-
Custom REST API end points: The
@RepositoryRestResource
annotation specifies a custom path, e.g.,@RepositoryRestResource(path="members")
. -
Pagination: By default, Spring Data REST returns 20 items per page. You can control the page size and change pages using query parameters, e.g.,
http://localhost:8080/employees?page=1
. -
Sorting: You can sort by entity properties.
http://localhost:8080/employees?sort=lastName
will sort ascending bylastName
.http://localhost:8080/employees?sort=firstName,desc
will sort descending byfirstName
. -
Configuration: You can configure Spring Data REST using properties in your
application.properties
file:-
spring.data.rest.base-path
defines the base path. -
spring.data.rest.default-page-size
sets the default page size. -
spring.data.rest.max-page-size
sets the maximum page size.
-
What is JSON?
- JSON (JavaScript Object Notation) is a lightweight data-interchange format that's used to transmit data between a server and a web application.
- It acts as the common language for communication between your REST API and other applications.
Real-Time Project
- Spring Boot can create a REST API that connects to a database.
REST Examples
- PayPal Invoicing API: https://developer.paypal.com/docs/api/invoicing/
- GitHub Repositories API: https://developer.github.com/v3/repos/#repositories
- SalesForce REST API: https://sforce.co/2J40ALH
Anti-Patterns
-
Don't Include Actions in the Endpoint:
- Bad:
/api/employeesList
,/api/deleteEmployee
, etc. - Good: Use HTTP methods for actions.
- Bad:
