Hibernate 为什么Grails中的Spock规范会导致'；projectname.Event实例的标识符已从1更改为2'；？

运行

测试应用程序集成：spock

会导致以下错误：

的实例的标识符 projectname.Event已从1更改为 至2；嵌套异常是 org.hibernate.HibernateException：的实例的标识符 projectname.Event已从1更改为 到2

org.springframework.orm.hibernate3.HibernateSystemException： 的实例的标识符 projectname.Event已从1更改为 至2

嵌套异常是 org.hibernate.HibernateException：的实例的标识符 projectname.Event已从1更改为 到2点 projectname.EventControllerSpec.save： 一 事件（EventControllerSpec.groovy:74）

原因： org.hibernate.HibernateException：的实例的标识符 projectname.Event已从1更改为 到2

这个问题从何而来？

如何解决这个问题？

[可选]是否有人可以创建标记“”

你的斯波克测试扩展了什么课程？它应该是

spock.lang.Specification

或

---

grails.plugin.spock.IntegrationSpec

而不是为单元测试设计的

grails.plugin.spock.ControllerSpec

。

如果您可以发布事件的定义，可能会有所帮助。另外，您使用什么数据库进行集成测试？我尝试了MySQL和HSQLDB；你认为域类的定义对这一点有什么影响？嗨，Peter，我在开发的后期将规范从单元转移到了集成（因此仍然扩展了ControllerSpec）。现在，按照您的提示并更改为IntegrationSpec（或spock.lang.Specification）将删除对“controller”的访问（没有这样的属性：controller for class:corilla.EventControllerSpec）。我试过几种方法来找回它（新的…（），Mock（）），但显然我做错了什么…正确。IntegrationSpec没有“控制器”属性。您必须自己实例化控制器并连接到任何服务或其他Springbean中。这是集成测试的标准实践。顺便问一下，为什么要对控制器使用集成测试？它的价值通常很低，而访问数据库的服务的集成测试的价值通常较高。
