deleted object would be re-saved by cascade (remove deleted object from associat

阅读更多

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

 

 

我一般采用方法2,方法3设置为CascadeType.REMOVE,会把主表记录也删除。
