Spring boot mongoclient preferred configuration

I wanted to ask what is the best way to configure MongoClientOptions for MongoClient bean using spring boot. For instance I want to set readPreference to secondary. For some of mongodb connection configuration I can provide settings using application.yml file and 'spring.data.mongodb' properties. Is there a way to specify it also as a property, or it has to be done with java configuration? Could you redirect me to some decent examples?

Looking over the autoconfig classes in the boot repo is where I usually start:

https://github.com/spring-projects/spring-boot/tree/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/mongo

If you look at MongoAutoConfiguration.java, you can see that it will attempt to autowire a bean of type MongoClientOptions. If you just create a @Bean of this class in your application, I believe it will use that configuration. As far as I can tell, only a few of the configuration properties are currently configurable in the application.yml (see the MongoProperties.java class for the full set).

I can't say this is the "best" way, but I suspect it is what the author intended up to this point. I could definitely see an enhancement being made to the configuration properties that allows more of the client options to be set via properties (and that would feel more "booty" IMO).
