Only expose certain fields when viewing specific item with Spring Data?

Question

I\'m currently using Spring Boot to create a REST API with a mongodb backend. Is it possible to only expose certain fields when viewing a specific item, and not a list of it

Answer 1

You have to add @Query annotation on the find method in the repository and specify the fields parameter:

public interface PersonRepository extends MongoRepository

  @Query(value="{ 'firstname' : ?0 }", fields="{ 'firstname' : 1, 'lastname' : 1}")
  List findByThePersonsFirstname(String firstname);

}
