Using @EnableJdbcRepositories and extending JdbcConfiguration causes duplicate bean registrations [DATAJDBC-243]

[spring-projects-issues]

Mark Paluch opened DATAJDBC-243 and commented

@EnableJdbcRepositories imports JdbcConfiguration which prevents users from extending from JdbcConfiguration in their code when using Spring Boot 2.1 with strict override detection.

In any case, this arrangement causes bean overrides and sorting out the priority in which beans are registered causes trouble for users.

We should remove the JdbcConfiguration import and leave it to users to import the required configuration.
In a second step, we should conditionally register the required components (RelationalMappingContext, RelationalConverter) within JdbcRepositoryConfigExtension to align with other store modules
