BootStrap.groovy导致grails失败

将旧的2.2.2应用程序迁移到3.1.2，我能知道为什么这个应用程序会因为bootstrap.groovy而崩溃吗 任何帮助都将不胜感激，谢谢

使用：grails 3.1.2，mysql workbench 6

这是Bootstrap.groovy，它会导致整个应用程序停止运行

import grailsapp.Location;
import grailsapp.State;
import grailsapp.User;
import grailsapp.Type;

class BootStrap {

    def init = { servletContext ->

        new State(state: "Issuable", updates: [:]).save(failOnError:true)
        new State(state: "Holding", updates: [:]).save(failOnError:true)
        new State(state: "In for repair", updates: [:]).save(failOnError:true)

        new Location(location: "L163", specific: "Rack 3A", updates: [:]).save(failOnError:true)
        new Location(location: "L163", specific: "Rack 3B", updates: [:]).save(failOnError:true)
        new Location(location: "L163", specific: "Rack 3C", updates: [:]).save(failOnError:true)

        new User(username:"blah", password: User.hashPassword("password"), firstName:"blah", lastName:"blah", isAdmin:true, updates:[:]).save(failOnError:true)

        new Type(type:"Dell E6500").save(failOnError:true)
        new Type(type:"Dell E6510").save(failOnError:true)
        new Type(type:"Dell E6520").save(failOnError:true)

    }
    def destroy = {
    }
}

这些是它导致的错误

看起来

状态

上的

更新

字段是一个

集合

，但您正在使用

映射对其进行初始化。尝试：

new State(state: "Issuable", updates: []).save(failOnError:true)
new State(state: "Holding", updates: []).save(failOnError:true)
new State(state: "In for repair", updates: []).save(failOnError:true)

在看到State类之后，我检查了“updates”字段是否是一个hasMany关系。它表示从0到多个对象的关系。我的意思是，指定更新不是必须的，因此如果您编写的state类没有更新，那么它必须是有效的：

新状态（状态：“可发行”）
新州（州：“控股”）
新状态（状态：“待维修”）

您现在的问题是，如果您尝试：

新状态（状态：“可发布”，更新：[：]）。保存（FailOneError:true）或
新状态（状态：“可发布”，更新：[]）。保存（FailOneError:true）

您将得到一个错误，因为更新不是地图或列表。它必须是“Update”类的对象。
C:\dir\init\BootStrap.groovy:6:无法解析第6行第3列的类状态。新状态（状态：“保持”，更新：[]）。保存（FailOneError:true）^可能没有很好的理由在保存之前初始化
更新。请尝试Grails 3.1.1或3.1.3。3.1.2版本的验证存在一些错误。刷新您的保存。*。保存（failOnError:true，flush:true）
