在 Spring Boot 中創建 bean jpaMappingContext 時出錯

Question

我收到這個錯誤，我不明白為什么，我剛剛開始通過制作一個網站來學習 springframework。我添加了所有的錯誤，也許它會更容易幫助我，因為我真的不明白為什么會出現這個錯誤，我有專制的二傳手。 如果有人有任何想法可以，我刪除了有人可以幫忙嗎？

Answer 1

如錯誤消息中所述：

無法確定類型：com.deiutz.BuildIT.User.products.cos，表：users，列：[org.hibernate.mapping.Column(cos)]

您正在使用這樣的屬性：

私人cos；

Hibernate 不理解這種類型。 如果這不打算在架構中使用，則將其標記為：@Transient

Answer 2

正如 Faizan 所寫，Hibernate 不知道如何映射 cos 類型。 要么不保留它（@Transient）或定義一個映射 - 可能你想將它保存為 JSON 類型，其中 hibernate-types https://github.com/vladmihalcea/hibernate-types可以提供幫助。 您還可以在https://bootify.io 上創建架構，包括 JSON 類型。
