解决hibernate 删除异常: deleted object would be re-saved by cascade (remove deleted object from associations)
在hibernate 删除关联时会出现eleted object would be re-saved by cascade (remove deleted object from associations)的异常,结合别人的和自己的经验通常有三种解决的方案:
方法1 删除Set方的cascade:
方法2 解决关联关系后,再删除
onside.getManys().remove(thisMany); //在所关联的一方的set中移走当前要删除的对象
thisMany.setOne(null); //设置所对应的一方为空,解除它们之间的关系
manyDao.delete(thisMany);
方法3 在many-to-one方增加cascade 但值不能是none
