mysql - 在 JPA 中找不到实体实体类实例变量的属性

Question

我创建了一个患者实体类并将患者 ID 实例变量声明为主键。我在需要的地方使用每个 patientId ，但在我使用的地方没有 patientid 。当我运行我的应用程序时，我在运行时遇到此类错误。我正确检查了我的应用程序但我无法找到我的错误

Caused by: org.springframework.data.mapping.PropertyReferenceException: No property patientid found for type Patient! Did you mean 'patientId'?
