hibernate criteria projections 映射使用

Criteria criterion=super.getSession().createCriteria(PaymentRecord.class);
criterion.add(
Restrictions.and(
Restrictions.eq("worker", worker),
Restrictions.eq("status", Constants.paymentrecord_status_confirmed),
Restrictions.ge("createTime", start),
Restrictions.le("createTime", end)
));//传递restrictions ，增加查询条件
criterion.setProjection(
Projections.projectionList()
.add(Projections.sqlGroupProjection(
"sum(amount) as amount,date(createTime) as day", //设置计算函数和返回值
"DATE(createTime) order by day asc", //设置group ，并且加入order
new String[]{"amount","day"},//记录 值变量
new Type[]{BigDecimalType.INSTANCE,DateType.INSTANCE}))//设置值类型
//  .add(Projections.groupProperty("worker"))//在此可增加group property
.add(Projections.rowCount())
);
criterion.setResultTransformer(Transformers.aliasToBean(DaysIncome.class));//设置 bean vo,此bean的属性要和以上 查询返回的属性一致包括类型，否则 会最终出现异常
@SuppressWarnings("unchecked")
List<DaysIncome> ls=criterion.list();
return ls;

华丽的分割线，以下为一复杂应用 -----------------------------------------------------

Criteria categoryCriteria = sessionFactory.getCurrentSession().createCriteria(TaskCategorySummary.class, "c");
//                .createAlias("c.favorite","f");
categoryCriteria.createAlias("requesterAccount", "r");
//                .setProjection(Projections.count("f.id").as("favoriteCount"))
categoryCriteria.setProjection(Projections.projectionList()
.add(Projections.property("r.name").as("requesterAccount"))
