我正在尝试使用动态查询实现搜索查询 我创建了像这样的动态查询
DynamicQuery dynamicQuery=DynamicQueryFactoryUtil.forClass(OrderSubscription.class,PortletClassLoaderUtil.getClassLoader());
DynamicQuery dynamicQueryCount=DynamicQueryFactoryUtil.forClass(OrderSubscription.class,PortletClassLoaderUtil.getClassLoader());
Criterion criterion = RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.ORDERNO, StringPool.PERCENT+searchKeyword+StringPool.PERCENT);
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.STATUS, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.ORDERDATE, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.PAYMENTSTATUS, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.ORDERSTATUS, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.ORDERID, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.PAYMENTTRANSACTIONTYPE, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.STARTDATE, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
criterion = RestrictionsFactoryUtil.or(criterion, RestrictionsFactoryUtil.like(DBConstants.OrderSubscription.CANCELDATE, StringPool.PERCENT+searchKeyword+StringPool.PERCENT));
dynamicQuery.add(junctionOR);
dynamicQueryCount.add(junctionOR);
List<OrderSubscription> orders = OrderSubscriptionLocalServiceUtil.dynamicQuery(dynamicQuery, start, end);
现在投掷错误

摘要：
我想根据来自DB的搜索关键字获取列表 和我的DB列类型id datetime。
任何人都可以帮我解决这个问题
