休眠“对象引用了未保存的瞬态实例”问题

时间：2018-09-06 06:56:18

标签： java hibernate

我阅读了很多有关我的问题的文档，但是建议无法解决我的问题，所以我不得不打开这个主题。

我的问题是，当我尝试保存实体时，出现以下错误。 我添加了实体类。谢谢。

保存代码 

 @Transactional
@Override
public void saveEmployee(EmployeeTable employeeToSave)
{
    employeeDao.saveOrUpdate(employeeToSave);
}

2 个答案:

答案 0 :(得分：0)

将CascadeType.PERSIST与使用saveOrUpdate混合使用时，会出现此问题，该@org.hibernate.annotations.Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE) 可用于持久化实体（JPA专有）的操作。

有两个选项：

选项1：

将以下CascadeType添加到收集字段：

employeeDao.persist(employeeToSave);

选项2：

CascadeType.PERSIST是JPA专有的，对persist（）有影响。 有关更多信息：http://www.objectdb.com/api/java/jpa/CascadeType。如果使用JPA，则应将Dao更改为使用persist，而不是saveOrUpdate。

ConstraintSet constraintSet = new ConstraintSet();
constraintSet.clone(constraintLayout);
constraintSet.setVisibility(childView.getId(), View.VISIBLE);
constraintSet.applyTo(constraintLayout);

答案 1 :(得分：0)

调试非常困难，我认为您必须在EmployeeTable实体中检查“ graduation”对象，实际上它可能不为null，但尚未存储在数据库中，并且在保存EmployeeTable对象时不会持久保存，它是抛出“对象引用了未保存的瞬态实例”异常
