case when 无法执行，为什么 HibernateJavaORMDAOServlet

Hql 语句：
select sum(case when to_char(t.accountinoutDate,'yyyymmdd hh24:mi:ss') < to_char(to_date('2010-07-01 00:00:00','yyyy-mm-dd hh24:mi:ss'),'yyyymmdd hh24:mi:ss') then (case when t.accountinoutDirection = 0 then 1 else -1 end) * t.accountinoutMoney end) as startmoney, t.inneraccountsCode,t.orgCode from FundAccountinout t
group by t.inneraccountsCode,t.orgCode

报错：

原因是红色部分，即类名写错了，严格区分大小写
case when在hibernate中是可以使用的，但是语法比较严格
hql语句应改为(注意红色部分)
select sum(case when to_char(t.accountinoutDate,'yyyymmdd hh24:mi:ss') < to_char(to_date('2010-07-01 00:00:00','yyyy-mm-dd hh24:mi:ss'),'yyyymmdd hh24:mi:ss') then ((case when t.accountinoutDirection = 0 then 1 else -1 end) * t.accountinoutMoney) end) as startmoney, t.inneraccountsCode,t.orgCode from FundAccountinout t
group by t.inneraccountsCode,t.orgCode
另外注意，xml中需要<prop key="hibernate.query.factory_class">org.hibernate.hql.ast.ASTQueryTranslatorFactory</prop>
