Can I list all of the dataSources available?

Question

I would like to iterate over all the available dataSources for the current environment, trying to see if any of them contain a particular domain instance. Each environment has different dataSources.

The best I've hacked up so far is grailsApplication.config.findAll { it.key.contains('dataSource_') }. Is there a better or more legitimate way to do this?

Answer 1

You can also query against the bean names in the application context.

Something like

ctx.beanDefinitionNames.findAll{ it.contains( 'dataSource' ) }

At least that is what the DatasourcesUtils in the Datasources plugin does -
