Add $update support to MongoRespository (@Query annotation) [DATAMONGO-1253]

It would be great if the MongoRepository supported the $update operation to enable updating parts of a document. Right now the only way to do this with Spring Data MongoDB is to write code using a MongoTemplate

That's basically as expected. There's no point in exposing store specific API on the repository level as this would require the repository clients to be aware of the underlying persistence mechanism which to avoid is the exact purpose of a repository in the first place. Repositories are a level of abstraction, not just a more convenient template.

The actual way to go is to manually implement a custom method in the repository using the MongoTemplate API via a use-case specific method name

I should point out that spring-data-jpa does support the type of feature that I requested. See http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.modifying-queries

Good one! I thought you were asking for dedicated methods on the repository. Reopened for more detailed consideration
