This guide will help you sympathise the Residual API projects with lawmaking examples on Github. We have a number of manufactures explaining these projects. These code examples will help beginners and experts to acquire and proceeds expertise at developing RESTful Services with Spring Boot.

All Articles updated to 2.three.one.RELEASE of Spring Boot.

Spring Boot REST API Projects - Code Examples on Github

Allow's await at the manufactures in the following sections

  • Projects Creating Bones REST API
  • Adding Unit and Integration Tests to RESTful Services
  • Securing RESTful Services
  • Basic RESTful Service Features
  • Advanced RESTful Service Features

Projects Creating Basic REST API

We explore couple of options of create RESTful Services with Bound Boot

  • Using Spring Boot Spider web Starter
  • Using Spring Information REST Starter

Using Jump Boot Web Starter, we accept articles with

  • An article focusing on nuts of a Remainder Service
  • A project exposing an stop to end Grime API for an entire Resources. The project uses JPA (Hide) to connect to a H2 in memory database.

Adding Unit and Integration Tests to RESTful Services

Automation Tests (including Unit and Integration Tests) are a key part of ensuring your services and APIs evolve over a time period.

Let'southward consider a StudentController which depends on StudentService.

In the unit examination

  • We will mock out the StudentService using Mockito
  • Nosotros will use Mock MVC framework to launch only StudentController.

A primal part of unit testing is to restrict the scope to a minimum. In this unit test, nosotros want to exam only the methods in StudentController.

In the integration test

  • Nosotros volition launch the consummate Leap Boot application using @SpringBootTest
  • Nosotros will invoke the service methods using TestRestTemplate
  • We will affirm the results using a cracking JSON assert framework - org.skyscreamer.jsonassert.JSONAssert

A key part of integration testing is testing all the layers in the application.

Securing RESTful Services

In the commodity below, nosotros implement basic security for a Residuum API.

Bones RESTful Service Features

Great Balance APIs take

  • Awesome Exception Handling - Y'all would desire to render the correct response with the exact response status based on the situation.
  • Proper Validation - You would want to validate the right stuff and return a message which helps the consumer understand what failed.
  • Current Documentation - A Consumer need to understand how to utilize your API. Great documentation makes your consumer and your chore like shooting fish in a barrel.

Articles below explore these features in depth.

Remainder API Advanced Features

At the next level, Remainder APIs accept

  • HATEOAS - HATEOAS stands for "Hypermedia as the engine of application country". When some details of a resource are requested, you will provide the resources details likewise equally details of related resources and the possible actions you can perform on the resources. For case, when requesting information well-nigh a facebook user, a Residue service tin can return the following
    • user details
    • Links to go his recent posts
    • Links to get his recent comments
    • Links to think his friend'southward list.
  • Content Negotiation - Why should JSON be the just information exchange format to be supported? What if your consumer loves (or is stuck with) XML? Content Negotiation helps you support multiple data exchange formats for your RESTful API.
  • Versioning - As your API evolves with your and your consumer needs, yous would have the demand to have multiple versions of the same Resources API. How practice you handle that?
