[Jpa 框架 erupt模板 ] 报错:org.hibernate.PropertyValueException

Dear 丶 2023-10-04 14:34 6阅读 0赞

因为这个属性, 我当时数据库的属性是null值; 在删除数据的时候报错:  
如果 实体类 这个属性对应的数据库字段有值 删除就不会报错: 没有值就会报错; 我就把下图红框的删除了 ,删除数据成功  
题外话: 这里主键使用的是 BIgint

*  org.hibernate.PropertyValueException: not-null property  
    references a null or transient value

**unique=true是指这个字段的值在这张表里不能重复，所有记录值都要唯一，就像主键那样;  
nullable=false是这个字段在保存时必需有值，不能还是null值就调用save去保存入库;**
