Spring数据和带有@Query注释的mongodb数组

Question

I have the class:

public class Game {

@Id
private Integer gameId;

private int prize;
private int[] numbers;

//gets and sets

}

then I have the mongorepository class:

public interface GameRepository extends MongoRepository<Game, Integer> {

    @Query(value = "{ 'numbers' : {$all : [?0] }}")
    public List<JogoLotoFacil> myFind(int[] numbers);

}

When I execute the query straight onto mongodb I get the results that I want, but running on java with spring data I always get an empty list.

If I run findAll() I get the correst list.

Question is: is it possible to use @Query for arrays?

Answer 1

The custome @Query annotation is buggy for some operators. Would suggest to create your own custom interface and your implementation class to execute the custom query using the MongoTemplate. For example, create an interface with a name that appends Custom:

public interface GameRepositoryCustom {
    public List<JogoLotoFacil> myFind(int[] numbers); 
}

Modify the GameRepository and add the GameRepositoryCustom interface to be extended:

@Repository
public interface GameRepository extends GameRepositoryCustom, MongoRepository {

}

Create your implementation class to implement the methods defined in GameRepositoryCustom interface.

public class GameRepositoryImpl implements GameRepositoryCustom {

    @Autowired
    MongoTemplate mongoTemplate;

    @Override
    public List<JogoLotoFacil> myFind(int[] numbers) {
        return mongoTemplate.find(
            Query.query(Criteria.where("numbers").all(numbers)), Game.class);
    }
}
