Documentation: Extension Development

Step-by-Step Guide

1. Create maven submodule

The different STA Profiles (vanilla, citsci, ufzaggregata) are currently organized in different maven submodules. It is recommended to create a new submodule if major new functionality is to be added. See Module Documentation for a overview about the existing modules

2. Add Profile to loading routine

The profiles are loaded using Spring @Profile Annotations. The currently active profile can be set in application.yml

• To prevent default loading of the extension the Application.java needs to be adjusted to exclude any profile-specific packages: Example
• The specific loading is then done by a profile-specific loader, e.g. this loader for ufzaggregata: Example

3. Implement custom @Components

To implement a full dao persistence layer, start by implementing an EntityServiceFactory that provides the http/mqtt layers with a central point for requesting entity-specific services for data persistence/retrieval
