为什么 Grails 中的 Spock 规范会导致“projectname.Event 实例的标识符从 1 更改为 2；”？

Question

运行test-app integration:spock 会导致以下错误：

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

org.springframework.orm.hibernate3.HibernateSystemException： 实例的标识符 projectname.Event 从 1 更改 到 2;

嵌套异常是 org.hibernate.HibernateException：实例的标识符 projectname.Event 从 1 更改 到 2 在 项目名称.EventControllerSpec.save： 一个 事件（EventControllerSpec.groovy:74）

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

1. 此问题源于何处？
2. 如何解决？
3. [可选] 有人可以创建标签“spock”吗？

    when: "I save that event"
    def result = controller.save() // THIS IS LINE #74 AS STATED IN THE ERROR

    then: "The event is successfully saved and the show-view rendered"

您的 Spock 测试扩展了什么类？它应该是spock.lang.Specification 或 grails.plugin.spock.IntegrationSpec 而不是为单元测试而设计的grails.plugin.spock.ControllerSpec。
