让hibernate支持递归、start with connect by prior 查询
由于hibernate的结果对象映射功能很好用，但是有些特殊的sql文hibernate并不支持，比如start with connect by prior，如何让hibernate支持这种特殊sql查询，还能使用hibernate的对象功能呢。方法如下：
1、普通sql文:select {city.*} from T_IP_CITY_INVEST city start with city.PROFESSION_AUDITOR = ‘wuy’ connect by prior city.PARENT_PROJECT_CODE = city.PROJECT_CODE and order by city.id
2、使用方法
this.getSession().createSQLQuery(sql).addEntity(“city”, TIpCityInvest.class)
.list();即可，从上面可以看出，和普通sql文最大的区别就是 {city.*}，这个实际上就是把查询结果集转为映射对象。
3、hibernate解析后的sql文:
Hibernate:
