# ![RealWorld Example App using Kotlin and Spring](example-logo.png) > ### Spring boot + MyBatis codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the [RealWorld](https://github.com/gothinkster/realworld-example-apps) spec and API. This codebase was created to demonstrate a fully fledged fullstack 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](https://github.com/gothinkster/realworld) repo. # How it works The application uses Spring boot (Web, Mybatis). * Use the idea of Domain Driven Design to separate the business term and infrastruture term. * Use MyBatis to implement the [Data Mapper](https://martinfowler.com/eaaCatalog/dataMapper.html) pattern for persistence. * Use [CQRS](https://martinfowler.com/bliki/CQRS.html) pattern to separate the read model and write model. And the code organize as this: 1. `api` is the web layer to implement by Spring MVC 2. `core` is the business model including entities and services 3. `application` is the high level services for query with 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 (for now), can be changed easily in the `application.properties` for any other database. # Getting started You need Java installed. ./gradlew bootRun open http://localhost:8080 # Try it out with [Docker](https://www.docker.com/) You need Docker installed. docker-compose up -d # Run test The repository contains a lot of test cases to cover both api test and repository test. ./gradlew test # Help Please fork and PR to improve the code.
