If you have complex types like javax.sql.DataSource and wants to allow to configure this via spring boot autoconfiguration in application.properties - then the generated spring boot classes with all the options will use getter/setter of types javax.sql.DataSource. That seems correct, but the spring-boot tooling itself (that generates additional json file) will skip those as it only support primitives and string types.
So we may need to fool, and generate the getter/setter as String type as you use it for configuring it as a bean reference by id anyway, eg
camel.component.jdbc.data-source = #myDataSource
We can add in the javadoc that the type is javax.sql.DataSource.
