我已经盯着这个问题太久了。当执行 .list() 行时,spring 会抛出关于 .add(Restrictions.in("LocationCode", locations)) 的异常 java.util.Arrays$ArrayList 不能转换为 java.lang.String。
Restrictions.in 期待 (string, Object[]) no??
有人可以指出我在传递到 Restrictions.in 时缺少什么吗?
public List getIDsByDivision(String SelectedAccountCode,
List SelectedDivision, String SelectedLocation) {
List IDs=null;
String result="--Select--";
Session session=null;
String[] locations=SelectedLocation.split(",");
try
{
session=sessionFactory.openSession();
if(null!=SelectedAccountCode && !SelectedAccountCode.equals("--Select--")
&&SelectedDivision.size()>0&&!SelectedDivision.equals("--Select--")
&&locations.length>0&&!SelectedLocation.equals("--Select--"))
{
IDs=session.createCriteria(Customer.class)
// TODO fix this to location
.setProjection(Projections.distinct(Projections.property("ID")))
.add(Restrictions.eq("AcctCode", SelectedAccountCode))
.add(Restrictions.eq("Division", SelectedDivision))
.add(Restrictions.in("LocationCode", locations ))
.list();
}
