    }

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

实体:

@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;
