Well both JPA and MongoDB config are basically beans, in case of JPA it's some kind of DataSource() bean and incase of MongoDB, it's the MongoTemplate() bean. But, if you are configuring the beans using application.yaml with built in properties like spring.data spring.data.xxx or spring.mongo.xxx If I understood correctly what you meant by

configuration changes

then you are meaning feature toogle. In that case there are a number of ways to achieve that in Spring. @ConditionalOnPropety, @ConditionaOnMissingBean, Spring profiling - @ActiveProfile etc.

It basically depends on your particulary use case. Aditionally you can make disable any bean injection like as follows:

(@Autowired(required=false))

That way, any bean injection can be avoided.
