Getting values ​​using boolean field in sleep mode

I am using postgres and I have a table like this:

    CREATE TABLE entity_transaction
    (
      id bigint NOT NULL DEFAULT nextval('entity_transactionid_seq'::regclass),
      transaction_ref character varying(11) NOT NULL,
      transaction_type character varying(10) NOT NULL,
      is_remitted boolean DEFAULT false);

      

        
        
        
      

    

I created a model class as follows for this table.

    @Entity
    @Table(name = "entity_transaction")
    public class Transaction implements Serializable {

        private static final long serialVersionUID = 1L;

        @Id
        @Column(name = "id")
        Long id;

        @Column(name = "transaction_ref")
        String transactionRef;

        @Column(name = "transaction_type")
        String transactionType;

        @Column(name = "is_remitted")
        Boolean isRemitted;

      

        
        
        
      

    

I'm just trying to get values ​​from this table using the supplied "isRemitted", true or false. For this I am trying the following query

    @Repository(value = "collectionsRepositary")
    public class CollectionsRepositoryImpl implements CollectionsRepository {

        @Resource
        private SessionFactory sessionFactory;

        @Override
        public List<Transaction> getUnmatchedList() {
            Query query = createQuery("select t from Transaction where t.transactionType = 'c' and t.isRemitted is true");      
            return query.list();
        }

        public Query createQuery(String queryString) {
            return getSession().createQuery(queryString);
        }

        private Session getSession() {
            return sessionFactory.getCurrentSession();
        }
    }       

      

        
        
        
      

    

But I cannot get the values ​​returning an empty list. This table has data that contains this boolean and the type of transaction.

Can anyone give me the correct way?

thanks in advance,
