Course: Server side implementation of REST architecture

This project shows the implementation of REST architecture using Spring Boot and Spring Data JPA with QueryDSL. For mapping Entities to Dtos is used the ModelMapper framework (If performance matters consider MapStruct framework). Documentation for that REST API is implemented in the Swagger framework.

Starting up Project (NOT implemented yet)

You don't have to install Java, Maven, Tomcat, etc. to your local development environment. All you need is [Vagrant installed] (http://docs.ansible.com/ansible/latest/guide_vagrant.html).

vagrant up

Now check that documentation on the following section is reachable. NOTE: This command will also insert some testing data to data storages.

Documentation

Documentation is done in Swagger framework. It is possible to reach it on the following page:

~/rest-training/api/v1/swagger-ui.html

e.g. on localhost it should be:

http://localhost:8080/rest-training/api/v1/swagger-ui.html

ADOC version of REST API documentation is generated here: (https://github.com/SedaQ/rest-training/blob/master/doc-files/ApiDocumentation.adoc)

PDF version of REST API documentation is generated here: (https://github.com/SedaQ/rest-training/blob/master/doc-files/ApiDocumentation.pdf)

NOTE: please note that client for that REST API could be generated using [Swagger codegen] (https://swagger.io/tools/swagger-codegen/). It is crucial to annotate each RestController method properly!

server.port={port for service}, e.g., 8080

logging.level.org.hibernate=ERROR
logging.file = logs/rest-training.log  

3. Database migration

Prerequisities running PostgreSQL and created database named 'training' with schema 'public'. To migrate database data it is necessary to run this command:

$ mvn flyway:migrate -Djdbc.url=jdbc:postgresql://{url to DB}/rest-training -Djdbc.username={username in DB} -Djdbc.password={password to DB}

e.g.:

$ mvn flyway:migrate -Djdbc.url=jdbc:postgresql://localhost:5432/rest-training -Djdbc.username=postgres -Djdbc.password=postgre

NOTE: This script must be run in [persistence] (https://github.com/SedaQ/rest-training/tree/master/persistence) module.

Installing project

Installing by maven:

mvn clean install

Run project

In Intellij Idea:

  1. Click on "Run" -> "Edit configurations".
  2. Choose "RestConfigTraining" configuration.
  3. Add into "Program arguments" --path.to.config.file="{path to your config properties}".
  4. Run RestConfigTraining

Runnig project from cmd (after project is installed and database is migrated):

mvn spring-boot:run -Dpath.to.config.file=../ansible/properties/training.properties
