Mongodb @DBRef query spring

Question

I my spring project, I am using two models with a reference.

A model user which has a reference on a token object.

@Document(collection = "user")
public class User {

   @Id
   public String id;
   @DBRef
   public Token token;
}

Then my Token object:

@Document(collection = "token")
public class Token {

   @Id
   public String id;
   public String token;
}

I am trying to query a user from a token. I tried to create a MongoRepository interface :

@Repository
public interface UserRepository extends MongoRepository<User, String> {
    @Query(value="{ 'token.id' : ?0 }")
    User findByTokenId(String id);
}

But that's not working. How can I create such kind or request ?

Answer 1

you can use:

@Repository
public interface UserRepository extends MongoRepository<User, String> {
    @Query(value="{ 'token.id' : ?0 }")
    User findAllByToken_Id(String id);
}
