Improve documentation to reveal which artifact provides which configuration property

[ghferrari]

I'm using Spring Modulith 1.3.5 with Spring Data JPA and postgresql 16. I'm seeing issues with these two settings:

• spring.modulith.events.jdbc.schema-initialization.enabled
• spring.modulith.events.jdbc.schema

Neither property appears in Intellij Idea's completion suggestions, which suggests to me they're not defined when Spring Data JPA is in use.

Also, when I try to put Spring Modulith's tables inside a custom database schema named modulith and set spring.modulith.events.jdbc.schema to that value, I see this error:

Schema-validation: missing table [event_publication]

which likewise suggests that Spring Modulith is not using the defined schema value i.e. it's still looking in the public schema rather than the intended modulith schema.

That's correct, as our JPA integration ends at the JPA level and all database management is handled by your JPA provider or an alternative you configure. Thus, the spring.modulith.events.jdbc properties are only applied if the spring-modulith-events-jdbc module is used.

I'll use this ticket to augment the section of reference documentation listing the properties to include information about which artifact provides the corresponding property.

Thanks @odrotbohm . I'm mainly interested in being able to define a custom schema where the event_publication and event_publication_archive tables will live. Is there a way to configure Spring Modulith to use a custom schema when using JPA?

You'd need to use the configuration options of your JPA provider (Hibernate?) to achieve that. Note that you can also use the spring-modulith-events-jdbc module with an application that uses JPA as primary persistence mechanism.
