配置正确 删除修改级联不起作用分析：
删除直接用delete(object)删除
该object包含了所删数据的id,但是其他字段为空，外键关联不上，当前数据记录正常删除，级联失效
正确的逻辑应该是查出这个object 他有完整的数据 再进行delete ,update同样如此，问题完美解决。
正确写法：
@Override
public int deleteAwardModel(AwardModel awardModel) {
// TODO Auto-generated method stub
awardModel=(AwardModel) hibernateTemplate.getSessionFactory().getCurrentSession().get(AwardModel.class, awardModel.getUid());
hibernateTemplate.delete(awardModel);
return 1;
}
错误写法：
@Override
public int deleteAwardModel(AwardModel awardModel) {
// TODO Auto-generated method stub
hibernateTemplate.delete(awardModel);
return 1;
}
