使用插件中的域类

Question

我目前正在第一次尝试grails 3。

我创建了一个插件(应该包含一些域类)和一个简单的应用程序。

现在，我收到了以下错误：

Caused by: java.lang.IllegalStateException: Either class [de.foo.Author] is not a domain class or GORM has not been initialized correctly or has already been shutdown. Ensure GORM is loaded and configured correctly before calling any methods on a GORM entity.

作者域类：

class Author { 
  String name 
}

我正在取消Grails 3.2.9中的以下依赖项：

你们对我有什么建议或答案吗?我如何在插件中存储域类并在某些应用程序中使用它？

Answer 1

对于GORM错误，版本必须是相同的。对于其他grails，对于二进制兼容性，groovy版本通常必须是相同的。虽然在每一种情况下都不是100%要求每个版本保持相同，但在grails 3中它比grails 2更有必要，而且可能只是目前的最佳实践。
