Hibernate级联删除(一对多)

 

1. 当级联属性cascade="all"时，发现无法删除对一端的数据 
2. <set name="tripBusTravelSet" table="trip_bus_travel_depa_info" lazy="false" inverse="false" 
3.         cascade="all" sort="unsorted"> 
4.         <key column="TRIP_BUS_TRAVEL_ID" /> 
5.         <one-to-many class="com.myway.followme.model.bus.TripBusTravelDepaInfo" /> 
6.     </set>
7.  
8. 然后改成cascade="all-delete-orphan"时，可以实施级联删除
9. <set name="tripBusTravelSet" table="trip_bus_travel_depa_info" lazy="false" inverse="false"
   cascade="all-delete-orphan" sort="unsorted">
   <key column="TRIP_BUS_TRAVEL_ID" />
   <one-to-many class="com.myway.followme.model.bus.TripBusTravelDepaInfo" />
   </set>
