Convert result from HQL into Object

Question

This is my method in repository class :

@Query("select max(entry_fee) as maxBuyInFee, max(prize) as maxPrize, max(participants_number) as maxParticipants from Tournament tournament")
    FilterMaxValues findFilterMaxValues();

And this is my FilterMaxValues class :

public class FilterMaxValues {

    private Integer maxBuyInFee;

    private Integer maxPrize;

    private Integer maxParticipants;

How can i convert result from this HQL into FilterMaxValues object ?

Now i get :

No converter found capable of converting from type [java.util.HashMap] to type [com.test.FilterMaxValues]

Answer 1

You could use projections if your FilterMaxValues is not an entity, like

interface FilterMaxValues {

Integer getMaxBuyInFee();

Integer getMaxPrize();

Integer getMaxParticipants();

}
