Java 传递给持久化的JPA错误分离实体

我在提交表单时遇到以下错误：

org.hibernate.PersistentObjectException:传递给的分离实体 persist:com.project.pmet.model.Account；嵌套异常是 javax.persistence.PersistenceException： org.hibernate.PersistentObjectException:传递给的分离实体 坚持：com.project.stock.business.offer.Tarif

优惠：

日志错误：

我做错了什么？

如果您试图持久化一个新实体Tarif，那么请检查Tarif自动生成的id不在数据库中。看起来您试图持久化一个新实体，而持久化上下文已包含具有给定id的实体

---

如果要更新Tarif，请加载实体，然后更新或合并实体。

更新时使用的代码是什么？
