What is the best way to configure a bean override of MongoDatastore class in a Grails application that use GORM mongoDB plugin?

Question

In a standard Grails Application that use GORM MongoDB plugin, if you override the class MongoDatastore with a new one (for adding some custom behaviour) eg:

class MyMongoDatastore extends MongoDatastore{ 

      here the override methods and property

}

and you want to configure it to be used by plugin, what's the best approach to use?

Answer 1

In resources.groovy define the bean you're overriding and the class your overriding with:

beans = {
    mongoDatastore(MyMongoDatastore)
}

I've not used mongo before - assuming those names are correct given your example.
