We're creating a new PropertySource that uses a database as it's repository. The idea is that we can update property values at runtime. At the same time, we'd like to use @ConfigurationProperties to so we can include validation as well as use the application-{profile} naming conventions...
Database connections:The mysql database is inside Vagrant instance, and can be accessed via SSH to localhost with a private key file, which is also stored in the repository. There are no security issues with sharing private key or passwords in the project files, as this is lo...
