问题 I am using spring-data-mongodb and querydsl-mongodb to perform more flexible queries. My application has users and orders.

问题 I was wondering how to configure sharding in a spring config file. I took a look at this post http://krams915.blogspot.com.es/2012/02/mongodb-replica-sets-with-spring-data_9536.html and seems to work for a single replica set.
