Spring @Service that depends on Mongo

Question

I want to auto-configure a @Service only if Mongo was configured.

What's the appropriate way to do it?

My thought is to use:

@ConditionalOnBean(MongoTemplate.class)

Is there a better @Conditional method I should use instead?

Answer 1

Yes, you can use Conditional on property having specific value. Here is simple annotation:

@ConditionalOnProperty(value = "database.type", havingValue = "MONGO", matchIfMissing = true)

You can use the annotation for all beans related with the specified DB for example or create config that is conditional on property
