我已经创建了一个简单的grails应用程序和最新的v3.2.6。在grails-app/domain中创建了一个Authors和Book类。 Grails中，应用grails 3.2.6未能初始化测试数据“不是域类，或者GORM没有正确初始化”
书类/域看起来是这样的（我有一个书类也）
package org.softwood
//Author has many books logical model
class Author {
String name
Collection books
//static hasMany = [books:Book]
static constraints = {
books nullable:true
}
}
和书籍领域类的完整性
package org.softwood
class Book {
String title
Author author
//static belongsTo = [author:Author]
static constraints = {
author nullable:true
}
}
我开始应用 - 没有任何错误和试图用grails控制台创建Author的实例并得到这样的错误
java.lang.IllegalStateException: Either class [org.softwood.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.
so i编辑BootStrap.groovy来尝试像这样在启动时创建一个。为什么它没有正确地提出Gorm？
import org.softwood.*
class BootStrap {
def init = { servletContext ->
environments {
development{
createDevData()
}
test {}
production {}
}
}
def destroy = {
}
def createDevData() {
Author a = new Author(name:"will")
def res = a.save (flush:true, failOnExit:true)
assert res
assert Author.get(1).name == "will"
}
}
这个错误，当我开始用同样的消息，堆栈跟踪应用程序如下
java.lang.IllegalStateException: Either class [org.softwood.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.

怪异的小鬼。等待 - 报废，并重新创建一个全新的应用程序。重新创建了作者/书籍，并重新运行为集成测试 - 它工作，去控制台并在交互式控制台上键入 - 它的工作。所以我不知道为什么以前的新鲜安装不起作用 - 但明显破碎。非常奇怪 –
你的域类与你的'Application'类是否在同一个包中？如果不是，你可能需要重写'packageNames（）' –
不要graeme他们不是 - 默认的应用程序groovy是在包“包coffeeshopapp” - 与项目相同。域类位于“包org.softwood”中。正如我所提到的，在intellij中做一个gradle clean似乎再次修复 - 就像命令行中的run-app一样。如何重写“packageNames（）”不确定你的意思 –
