Liferay 带日期条件的动态查询

我正在尝试使用动态查询实现搜索查询 我创建了这样的动态查询

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);

总结：

我想从数据库中获取基于搜索关键字的列表 和我的DB列类型id datetime

有人能帮我解决这个问题吗

谢谢

我认为，问题是因为您正在为

Date

行设置

criteria=RestrictionsFactoryUtil.or（criteria，RestrictionsFactoryUtil.like（DBConstants.OrderSubscription.ORDERDATE，StringPool.PERCENT+searchKeyword+StringPool.PERCENT））参数不应该是
日期
对象吗？如果是，则考虑<代码>开始日期> />代码>代码>取消日期< /代码>。那么，什么类型的<代码> dBrimest.OrrordPosial.OrthDeals>代码>实际上是我从搜索字段中得到的关键字，因此它不能总是日期。我刚刚从API确认了方法
like
的第一个参数是
String
类型。首先，尝试删除包含日期参数的行并检查其是否有效，然后添加条件以检查
searchKeyword
是否是日期字符串，首先将其转换为
date
对象，然后传递给
like
方法。
