if you want to store the Enum type with int,you can:
    public Object nullSafeGet(ResultSet resultSet, String[] names, 
Object owner)
            throws HibernateException, SQLException {
        Object result = null;
        try {
            int index = resultSet.getInt(names[0]);
            if (!resultSet.wasNull()) {
                Object[] enumValue = enumValues.get(this.getClass());
                if (enumValue == null) {
                    Method method = null;
                    method = clazz.getDeclaredMethod("values", new 
Class[0]);
                    enumValue = (Object[]) method.invoke(null, new 
Object[0]);
                    enumValues.put(this.getClass(), enumValue);
                }
                result = enumValue[index];
            }
        } catch (Exception e) {
            e.printStackTrace();
            result = null;
        }
        return result;
    }

    public void nullSafeSet(PreparedStatement preparedStatement, 
Object value,
            int index) throws HibernateException, SQLException {
        if (null == value) {
            preparedStatement.setNull(index, Types.VARCHAR);
        } else {
            preparedStatement.setInt(index, ((Enum) value).ordinal());
        }
    }
