Spring Hibernate findByCriteria(...)方法 使用

Java代码

publicList < DispatchTask > findByCriteria
(DetachedCriteria criteria)
{
log.debug("findingDispatchTaskinstancebycriteria");
try
{
List < DispatchTask > results = getHibernateTemplate().findByCriteria
(criteria);
log.debug("findbycriteriasuccessful,resultsize:" + results.size());
returnresults;
}
catch (RuntimeExceptionre)
{
log.error("findbycriteriafailed", re);
throwre;
}
}

这是Service的片段
Java代码

publicList < DispatchTask > getByQuery(DispatchTaskinstance, DatequeryTime1,
DatequeryTime2)
{
StringtaskId = instance.getTaskId();
StringdeptName = instance.getDeptName();
Stringlinkman = instance.getLinkman();
StringplateNum = instance.getPlateNum();
ShortstatusId = instance.getStatusId();
DatequeryTime3 = null;
if (queryTime2 != null)
{
queryTime3 = newDate();
queryTime3.setTime(queryTime2.getTime() + (newLong("86400000")));
}
DetachedCriteriacriteria = DetachedCriteria .forClass(DispatchTask.class);
if (taskId != null && taskId != "")
{
criteria.add(Expression.like("taskId", taskId, MatchMode.ANYWHERE));
}
if (deptName != null && deptName != "")
{
criteria.add(Expression.like("deptName", deptName, MatchMode.ANYWHERE));
}
if (linkman != null && linkman != "")
{
criteria.add(Expression .like("linkman", linkman, MatchMode.ANYWHERE));
}
if (plateNum != null && plateNum != "")
{
criteria.add(Expression.like("plateNum", plateNum, MatchMode.ANYWHERE));
}
if (statusId != null && statusId != 999)
{
criteria.add(Expression.eq("statusId", statusId));
}
if (queryTime1 != null)
{
if (queryTime2 != null)
{
if (queryTime1.getTime() <= queryTime2.getTime())
{
criteria.add(Expression.between("dispatchDate", queryTime1,
queryTime3));
}
}
else
{
criteria.add(Expression.ge("dispatchDate", queryTime1));
}
}
}
else
{
if (queryTime2 != null)
{
criteria.add(Expression.le("dispatchDate", queryTime3));
}
}
returndispatchTaskDAO.findByCriteria(criteria);
}
