grails 3.2.6无法初始化测试数据＆＃34;不是域类或GORM尚未正确初始化＆＃34;

我用最新的v3.2.6创建了一个简单的grails应用程序。在grails-app / domain中创建了一个Authors和Book类。

grails-app / domain中的图书课程看起来像这样（我也有图书课程）

package org.softwood

//Author has many books logical model

class Author {

    String name
    Collection books

    //static hasMany = [books:Book]

    static constraints = {
        books nullable:true
    }
}

并预订完整性的域名

package org.softwood

class Book {

    String title
    Author author

    //static belongsTo = [author:Author]

    static constraints = {
        author nullable:true
    }
}

我启动了应用程序 - 没有错误，并尝试使用grails控制台创建一个Author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.

所以我编辑了BootStrap.groovy尝试在启动时创建一个这样的。为什么没有正确地提出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"
    }
}

当我使用相同的消息启动应用程序时出现此错误，堆栈跟踪如下

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.

答案 0 :(得分：0)

试试这个

package org.softwood

//Author has many books logical model

class Author {

    String name
    //Collection books

    static hasMany = [books:Book]

    static constraints = {
        books nullable:true    // you may not need this.
    }
}
