使用插件中的域类

Question

我目前正在尝试第一次 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 
}

我正在取消具有以下依赖项的 Grails 3.2.9：

你们对我如何在插件中存储域类并在某些应用程序中使用它有什么建议或答案吗？

Answer 1

对于 GORM 错误，版本必须相同。对于其他 grails 的东西，groovy 版本通常必须相同才能实现二进制兼容性。虽然并非 100% 要求在每种情况下都保持每个版本相同，但在 grails 3 中比在 grails 2 中更需要，并且可能只是目前的最佳实践。
