RealWorld Example App using Kotlin and Spring

Actions

Spring boot + MyBatis codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld spec and API.

This codebase was created to demonstrate a fully fledged full-stack application built with Spring boot + Mybatis including CRUD operations, authentication, routing, pagination, and more.

For more information on how to this works with other frontends/backends, head over to the RealWorld repo.

NEW GraphQL Support

Following some DDD principles. REST or GraphQL is just a kind of adapter. And the domain layer will be consistent all the time. So this repository implement GraphQL and REST at the same time.

The GraphQL schema is https://github.com/gothinkster/spring-boot-realworld-example-app/blob/master/src/main/resources/schema/schema.graphqls and the visualization looks like below.

And this implementation is using dgs-framework which is a quite new java graphql server framework.

How it works

The application uses Spring Boot (Web, Mybatis).

  • Use the idea of Domain Driven Design to separate the business term and infrastructure term.
  • Use MyBatis to implement the Data Mapper pattern for persistence.
  • Use CQRS pattern to separate the read model and write model.

And the code is organized as this:

  1. api is the web layer implemented by Spring MVC
  2. core is the business model including entities and services
  3. application is the high-level services for querying the data transfer objects
  4. infrastructure contains all the implementation classes as the technique details

Security

Integration with Spring Security and add other filter for jwt token process.

The secret key is stored in application.properties.

Database

It uses a H2 in-memory database sqlite database (for easy local test without losing test data after every restart), can be changed easily in the application.properties for any other database.

Getting started

You'll need Java 11 installed.

./gradlew bootRun

To test that it works, open a browser tab at http://localhost:8080/tags .
Alternatively, you can run

curl http://localhost:8080/tags

Try it out with Docker

You'll need Docker installed.

./gradlew bootBuildImage --imageName spring-boot-realworld-example-app
docker run -p 8081:8080 spring-boot-realworld-example-app

Try it out with a RealWorld frontend

The entry point address of the backend API is at http://localhost:8080, not http://localhost:8080/api as some of the frontend documentation suggests.

Run test

The repository contains a lot of test cases to cover both api test and repository test.

./gradlew test

Code format

Use spotless for code format.

./gradlew spotlessJavaApply
