Validation and persistence of definitions for field types, jurisdictions, case types and associated display elements.

Overview

Definitions are imported as an Excel spreadsheet which are parsed, persisted and then exposed as JSON through a REST API.

Spring Boot and Spring Data are used to persist the data in a PostgreSQL database. The database schema is created and maintained by Flyway change sets applied during application startup.

Moreover, if the feature is enabled, the ElasticSearch cluster is initialised when a definition file is imported. For each case type, an index, an alias, and a mapping is created on ElasticSearch. If failOnImport is true, any ES initialisation error will prevent the import to succeed. If false, ES errors are simply ignored

Getting started

Prerequisites

Environment variables

The following environment variables are required:

Name Default Description
DEFINITION_STORE_DB_USERNAME - Username for database
DEFINITION_STORE_DB_PASSWORD - Password for database
DEFINITION_STORE_DB_USE_SSL - set to true if SSL is to be enabled. false recommended for local environments.
DEFINITION_STORE_IDAM_KEY - Definition store's IDAM S2S micro-service secret key. This must match the IDAM instance it's being run against.
DEFINITION_STORE_S2S_AUTHORISED_SERVICES ccd_data,ccd_gw,ccd_admin,jui_webapp,pui_webapp,aac_manage_case_assignment Authorised micro-service names for S2S calls
IDAM_USER_URL - Base URL for IdAM's User API service (idam-app). http:https://localhost:4501 for the dockerised local instance or tunneled dev instance.
IDAM_S2S_URL - Base URL for IdAM's S2S API service (service-auth-provider). http:https://localhost:4502 for the dockerised local instance or tunneled dev instance.
USER_PROFILE_HOST - Base URL for the User Profile service. http:https://localhost:4453 for the dockerised local instance.
AZURE_APPLICATIONINSIGHTS_INSTRUMENTATIONKEY - secrets for Microsoft Insights logging, can be a dummy string in local

Building

The project uses Gradle wrapper.

This project uses TestContainers for the database testing support. Docker must be installed on the machine you are running tests.

To build project please execute the following command:

./gradlew clean build

Running

If you want your code to become available to other Docker projects (e.g. for local environment testing), you need to build the image:

docker-compose build

The above will build both the application and database images.
If you want to build only one of them just specify the name assigned in docker compose file, e.g.:

docker-compose build ccd-definition-store-api

When the project has been packaged in target/ directory, you can run it by executing following command:

docker-compose up

As a result the following containers will get created and started:

  • Database exposing port 5451
  • API exposing ports 4451

Handling database

Database will get initiated when you run docker-compose up for the first time by execute all scripts from database directory.

You don't need to migrate database manually since migrations are executed every time docker-compose up is executed.

You can connect to the database at http:https://localhost:5451 with the username and password set in the environment variables.

Modules

The application is structured as a multi-module project. The modules are:

repository

Data access layer.

domain

Domain logic.

rest-api

Secured RESTful API giving access to part of the domain logic.

excel-importer

Secured endpoint and specific logic for importing case definition as an Excel spreadsheet.

application

Spring application entry point and configuration.

Functional Tests

The functional tests are located in aat folder. The tests are written using befta-fw library. To find out more about BEFTA Framework, see the repository and its README here.
