@Convert doesn't work with Hibernate and QueryDSL

I have a table Incidencia with a CHAR (1 Byte) column visiblemovil. This column has 2 possible values: "S" or "N" (yes/no, si/no in Spanish) that I want convert to boolean using @Convert annotation. This is my code:

Converter:

@Converter
public class SiNoToBooleanConverter implements AttributeConverter<Boolean, String> {

    @Override
    public String convertToDatabaseColumn(Boolean aBoolean) {
        return aBoolean ? "S" : "N";
    }

    @Override
    public Boolean convertToEntityAttribute(String s) {
        return "S".equals(s);
    }
}

Entity:

@FilterDef(name = "PREGINCIDENCIA_FILTRO_FECHA", parameters = @ParamDef(name = "ultimaFechaSinc", type = "date"))
@Entity
public class Incidencia {

    private List<Incidenciapreguntas> preguntasList;

    private Integer codincidencia;

    private String descripcion;

    private Double horasfinalizacion;

    @Convert(converter = SiNoToBooleanConverter.class)
    private Boolean visiblemovil;

    private boolean tieneDocumentacion;

    @Id
    @Column(name = "CODINCIDENCIA")
    public Integer getCodincidencia() {
        return codincidencia;
    }

    public void setCodincidencia(Integer codincidencia) {
        this.codincidencia = codincidencia;
    }

    @Basic
    @Column(name = "DESCRIPCION")
    public String getDescripcion() {
        return descripcion;
    }

    public void setDescripcion(String descripcion) {
        this.descripcion = descripcion;
    }

    @OneToMany(mappedBy = "incidencia")
    @Filter(name = "PREGINCIDENCIA_FILTRO_FECHA", condition = "FMODIFICACION > :ultimaFechaSinc OR FMODIFICACION IS NULL")
    public List<Incidenciapreguntas> getPreguntasList() {
        return preguntasList;
    }

    public void setPreguntasList(List<Incidenciapreguntas> preguntasList) {
        this.preguntasList = preguntasList;
    }

    @Transient
    public boolean isTieneDocumentacion() {
        return tieneDocumentacion;
    }

    public void setTieneDocumentacion(boolean tieneDocumentacion) {
        this.tieneDocumentacion = tieneDocumentacion;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        Incidencia that = (Incidencia) o;

        if (codincidencia != null ? !codincidencia.equals(that.codincidencia) : that.codincidencia != null)
            return false;
        if (descripcion != null ? !descripcion.equals(that.descripcion) : that.descripcion != null) return false;
        return true;
    }

    @Override
    public int hashCode() {
        int result = codincidencia != null ? codincidencia.hashCode() : 0;
        result = 31 * result + (descripcion != null ? descripcion.hashCode() : 0);
        return result;
    }

    @Basic
    @Column(name = "HORASFINALIZACION")
    public Double getHorasfinalizacion() {
        return horasfinalizacion;
    }

    public void setHorasfinalizacion(Double horasfinalizacion) {
        this.horasfinalizacion = horasfinalizacion;
    }

//    @Basic
    @Column(name = "VISIBLEMOVIL")
    public Boolean getVisiblemovil() {
        return visiblemovil;
    }

    public void setVisiblemovil(Boolean visiblemovil) {
        this.visiblemovil = visiblemovil;
    }
}

When I execute a SELECT statement (with QueryDSL) I'm getting this error:

org.hibernate.exception.GenericJDBCException: Fail to convert to internal representation
javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Fail to convert to internal representation

Repository:

@Repository
public class IncidenciasDAO extends BaseDAO {

      public List<Incidencia> getIncidencias() {
        QIncidencia qIncidencia = QIncidencia.incidencia;
        JPAQuery query = new JPAQuery(entityManager);
        List<Incidencia> incidencias = query.from(qIncidencia).list(qIncidencia);
        return incidencias;
    }
}

You placed your mapping annotation on the getter for the mapped field in your entity class. According to chapter 2.3.1 of the specification, this leads to property-based access.

The specification states that only the getter should be annotated for the mapping. But perhaps that is not enough for the @Convert annotation?

You could try to annotate the field:

@Entity
public class Incidencia {

    @Column(name = "VISIBLE")
    @Convert(converter = SiNoToBooleanConverter.class)
    private Boolean visible;

    //other fields

    public Boolean getVisible() {
        return visible;
    }

    public void setVisible(Boolean visible) {
        this.visible = visible;
    }

}

(I corrected the name of the variable/field in your getter/setter methods.)

Your converter looks correct. The only thing is the @Basic annotation from your mapping. By definition, @Basic tells that an attribute is going to be persisted and a standard mapping will be used, so this can be an issue (Also I don't see any strong reason to mix @Basic and @Column in your case).

@Column(name = "VISIBLE")
@Convert(converter = SiNoToBooleanConverter.class)
public Boolean getVisible() {
    return visiblemovil;
}

Note: I haven't tested, but should solve the problem. Worth to try also moving annotations into the field, instead of getter.
