嵌套异常是org.hibernate.MappingException：无法获取org.hibernate.persister.entity.SingleTableEntityPersister的构造函数

Question

我正在尝试将一些记录插入到一​​个名为LOG的表中但无法使用hibernate和spring启动应用程序，使用构建器模式生成对象LogBuilder类也包含在普通实体类中。请建议减少这个问题。

Answer 1

经过一些谷歌搜索后我找到了答案，如果我们有getter方法，那么我们必须为每个属性设置setter方法，Hibernate假设将从数据库中读取值，所以为了设置这些值，它需要setter方法。

您的HistoryLogEntity

需要无参数构造函数
