Junit中eclipse中的Java play框架错误

Question

我正在 eclipse 中运行 play 框架，当我在 Junit 中运行一些 @Tests 时，似乎收到一些错误消息。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]

如果我从 application.conf 中删除 ebean.default="models.*" ，错误消息会发生变化，所以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 注释连接到持久性提供程序(并且已经在您继承的父类(super class)上运行增强)，但您没有运行该增强进入你的构建阶段。您需要确保增强步骤正在运行，并使用适当的 Eclipse 方面和/或 Maven 插件。
