저는 최신 v3.2.6의 간단한 grails 앱을 만들었습니다. grails-app/domain에 Authors와 Book 클래스를 만들었습니다. 오류없이 및 - Grails의-응용 프로그램에서grails 3.2.6 테스트 데이터를 초기화하지 못했습니다 "도메인 클래스가 아니거나 GORM이 제대로 초기화되지 않았습니다"
책 클래스/도메인 (나는 또한 책 클래스가) 내가 응용 프로그램을 시작
package org.softwood
class Book {
String title
Author author
//static belongsTo = [author:Author]
static constraints = {
author nullable:true
}
}
완전성에 대해
package org.softwood
//Author has many books logical model
class Author {
String name
Collection books
//static hasMany = [books:Book]
static constraints = {
books nullable:true
}
}
와 책 도메인 클래스 다음과 같습니다 저자의 인스턴스를 만들기 위해 grails 콘솔을 사용하려고 시도했는데 이런 오류가 발생했습니다.
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.
그래서 저는 BootStrap.groovy를 편집하여 이렇게 시작했을 때 시도해보십시오. 왜 Gorm을 제대로 기르지 못했을까요?
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"
}
}
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.

이상한 놈아으로하려고 다음과 내가 같은 메시지, 스택 추적과 함께 응용 프로그램을 시작하는이 오류가. 기다리는 동안 - 깨진으로 폐지하고 다시 새로운 앱을 다시 만들었습니다. 저자/책자를 다시 만들고 통합 테스트를 실행했습니다. 작동하고 대화 형 콘솔에서 콘솔에 입력 한 다음 작동합니다. 그래서 이전의 새로운 설치가 왜 작동하지 않았는지 전혀 알지 못합니다. 매우 이상한 –
도메인 클래스가 'Application' 클래스와 같은 패키지에 있습니까? 그렇지 않다면'packageNames()' –
을 무시해야 할 수도 있습니다. 기본 응용 프로그램 그루비는 "package coffeeshopapp"패키지에 있습니다 - 프로젝트와 동일합니다. 도메인 클래스는 "package org.softwood"에 있습니다. 내가 intellij에서 깨끗한 그라데이션을 수행했다는 언급은 커맨드 라인에서 run-app처럼 다시 고쳐지는 것처럼 보였다. 어떻게 당신이 무슨 뜻인지 확실하지 않은 "packageNames()"를 뜻합니까? –
