SpringBoot Spring Session JDBC does not work when lazy initialization is enabled

The initializer that creates the database tables isn't called. This causes the attempt to save the session to fail:

This is happening as nothing depends on the JdbcSessionDataSourceInitializer so, with lazy initialization enabled, it is never initialized. JdbcIndexedSessionRepository beans should be configured to depend on JdbcSessionDataSourceInitializer beans, and perhaps also on any other beans that may initialise the database such as Flyway and Liquibase.
