@Tests我在 eclipse 中运行 play 框架，当我在 Junit 中运行一些错误消息时似乎收到了一些错误消息。我得到的错误是

[error] c.a.e.s.d.BeanDescriptorManager - Error in deployment
javax.persistence.PersistenceException: Error with [models.PurchaseRequest] It has not been enhanced but it's superClass [class play.db.ebean.Model] is? (You are not allowed to mix enhancement in a single inheritance hierarchy) marker[play.db.ebean.Model] className[models.PurchaseRequest]

如果我ebean.default="models.*"从application.conf错误消息中删除更改，那么我认为这可能是问题的根源。

Play 期望您使用字节码增强（例如，AspectJ）将 JPA 注释连接到您的持久性提供程序（并且已经在您继承的超类上运行了增强），但您没有在您的建造。您需要确保使用适当的 Eclipse facet 和/或 Maven 插件运行增强步骤。
