本文介绍了一种使用CardtypeBizCom实例获取特定ID的卡片类型模型，并通过Mapper映射进行属性复制及修改的过程。示例中，首先通过GetModelByPK方法获取ID为421的卡片类型，然后使用Mapper进行对象映射，最后修改卡片类型的名称并添加到系统中。

  var t = CardtypeBizCom.GetInstance().GetModelByPK(421);
            var t2 = Mapper.Map<Cardtype, Cardtype>(t);//id没被过滤
          
            
            //copyObject(t, t2); 
            t2.Cardtypename = "4444";
            CardtypeBizCom.GetInstance().Add(t2)

今天遇到一个Hibernate报错【A different object with the same identifier value was already associated with the session】，百度翻译【具有相同标识符值的另一个对象已与会话关联】hibernate有三种状态：临时态、持久态、游离态。持久态保存在会话里，因此我认为错误原因应该是saveOrUpdate的之前执行过相同主键的对象操作，致使session中已含有相同主键的对象。②将相同主键持久化对象转化为游离态。

经过DEBUG发现，原来是因为 saveAll里面的List中的数据的字段全部为null，导致了主键冲突。所以，上面报错的意思就是主键冲突，需要检查下需要持久化的数据。使用了SpringBoot + JPA。

hibernate级联更新出现a different object with the same identifier value was already associated

注：使用注解配置映射关系时从数据库中查询出来再更新也有这个问题，需要在一方中将多方实体中的一方对象清空再执行更新否则也会报a different object with the same identifier value was already associated with the session错误。在执行更新方法时前端传入的班级对象，通常认为前端需要传一个班级的id进行关联这样会导致。此为个人遇到此问题解决的办法，大佬们如果有更好的解决办法，欢迎留言。解决办法：因为使用级联所以不需要班级的id关联，
