今天客戶方服務(wù)器上突然有一個功能保存了，查看日志信息后發(fā)現(xiàn)，錯誤信息：
Could not instantiate class XXX from tuple at AliasToBeanConstructorResultTransformer...
Google了很久才發(fā)現(xiàn)有可能是HQL語句中別名的問題，具體原因未知，現(xiàn)在處理辦法是，將下面的語句中的別名去掉：
StringBuffer hql = new StringBuffer("select new ContractItem(l, "
+ " pi.unitPrice, " + " pi.currencyType, " + "pi.currencyTypeDisplay," + " pi.units, "
+ " sum(pi.quantity + pi.adjQuantity), " + " pp, " + " pi.task) "
+ " from PurchasePlanItem pi " + " join pi.purchasePlan pp"
+ " join pi.priorList l " + " where l.supplierNo = ? "
+ " and pp.id in (");
具體是否可以解決，還要看一會兒的部署情況。
