SpringData MongoDB Using projection

spring-data, spring-data-mongodb

Solution

Here's the relevant section of the docs concerning repositories. Also the section on querying documents has a brief mention of it.

When using `MongoOperations` you can use the `Query` instance to restrict the result to certain fields:

Query query = Query.query(Criteria.where("lastname").eq("…"));
// Configure the field spec you want to use for this query
query.fields().include(…).slice(…);

I've filed DATAMONGO-839 to improve the discoverability of this and also polish the JavaDoc of the `Query` class.

Problem

Is their any way via which I can use mongodb projection feature to fetch selected fields from the document. Even after searching for whole day on internet not able to find any clue.
