I need to create java modules for existing Spring application. I have no experience regarding modules, but so far I've gathered I require to migrate existing packages to new module in order for new modules to work. When I run the app I get the following message:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

I understand this is due to application.properties. How can I define global properties. I have created .yml in resource package of said module, but I still get the same error. Also in order to boot all the modules I require something like docker?

  • Could you add more information, e.g. by providing a [minimal, reproducible example](https://stackoverflow.com/help/minimal-reproducible-example) of (an essential part of) your application? – qutax May 05 '20 at 15:23
