Add support for restricting results by document types in the @Query annotation [DATAMONGO-2151]

[spring-projects-issues]

tinesoft opened DATAMONGO-2151 and commented

Since #53, it is now possible to  restrict results of a query to specific types, thanks to the new 'restrict ()' method on the Query object.

it would be nice if this feature could be made available on the @Query annotation as well.

This could be done, for example, via a restrict parameter that would accept a array of Class<?>, just like the restrict method on the Query class.

For example:

@Query(restrict={BaseDoc.class, SpecialDoc1.class, SpecialDoc2.class})
BaseDoc findBySomething();

 

Of course i could also use:

@Query(" '_class': {'$in': ['com.mydomain.BaseDoc', 'com.mydomain.SpecialDoc1', 'com.mydomain.SpecialDoc2']}")
BaseDoc findBySomething();

 
to do the job, but i'm looking for a more typesafe approach. Beside i would like to still be able to use the query method mechanism to generate the actual query.
