将应用程序从 Grails 3.3.11 迁移到 Grails 4.0.6 后，我无法运行集成测试。当我尝试运行集成测试时，它会抛出错误：

在调查未来时，我发现
Grails 域类 API 已弃用 表示域类及其属性的遗留类已被弃用，取而代之的是映射上下文 API。
这样做的原因是为了避免在 GORM 和 Grails 之间重复解析相同的类数据并减少整体启动时间。
这些类中方法的内部实现现在委托给映射上下文。由于该更改，在应用程序上下文可用之前，有关您的域类的信息不可用。
例如，在以前的 Grails 版本中，可以访问 GrailsDomainClass 实例并检查插件中 doWithSpring 方法内的 GrailsDomainClassProperty 属性。
如果您有遵循该示例的代码，则会抛出一个错误，类似于“在 GORM 初始化之前无法访问该方法......”。解决方案是将在上下文可用之前执行的任何逻辑移动到在上下文可用之后执行的其他地方。
所有使用 GrailsDomainClass 或 GrailsDomainClassProperty 类的代码都应该重写以使用映射上下文 api。
首先，注入 grailsDomainClassMappingContext bean。有关 MappingContext、PersistentEntity (GrailsDomainClass) 和 PersistentProperty (GrailsDomainClassProperty) 的更多信息，请参阅 api 文档。
