Question

我正在尝试在Grails控制台中运行GORM方法（在运行命令grails console之后）。我正在使用 Grails 2.3.11 。这是我从控制台运行的代码：

import com.company.dualenroll.registration.DualEnrollStudent

DualEnrollStudent.list()

我希望这可以毫无问题地工作，但它会抛出异常。值得注意的是，DualEnrollStudent域类来自内联插件。这是堆栈跟踪：

java.lang.IllegalStateException: Method on class [com.company.dualenroll.registration.DualEnrollStudent] was used outside of a Grails application. If running in the context of a test using the mocking API or bootstrap Grails correctly.

确保从app文件夹中运行“grails console”。此外，您还需要在以下位置运行代码：

DualEnrollStudent.withTransaction { status -> // your code here }

否则你会得到一个异常，告诉你你没有初始化Hibernate会话。
