我正在将应用程序从 Grails 1.3.9 升级到 Grails 2.2.1。当我发出 run-app 命令时，我得到一个很长的堆栈跟踪，它以这个错误开头，然后或多或少地重复了大约 400 行：

我认为相关的部分是：

org.hibernate.MappingException: property [sponsoringManager] not found on entity [com.mycompany.myapp.ManagerDelegate]

这是 ManagerDelegate 域类的代码，它是一个多对多连接类：

package com.mycompany.myapp

class ManagerDelegate extends Base implements Serializable {

    static belongsTo = [sponsoringManager:User, delegate:User]

    boolean equals(other) {
        if (!(other instanceof ManagerDelegate)) {
            return false
        }
        other.sponsoringManager.id == sponsoringManager.id && other.delegate.id == delegate.id
    }

    static mapping = {
        id composite: [
            'sponsoringManager',
            'delegate'
        ]
        version false
    }
}

如您所见，ManagerDelegate 确实包含在 belongsTo 语句中声明的赞助管理器属性。这在 Grails 1.3.9 中完美运行。

这是用户类：

class User {
    static hasMany = [sponsoringManagers: ManagerDelegate, delegates: ManagerDelegate]
    static mappedBy = [sponsoringManagers: "delegate", delegates: "sponsoringManager"]

    static mapping = {
        id generator: 'uuid'
        sponsoringManagers cascade: 'all-delete-orphan'
        delegates cascade: 'all-delete-orphan'
    }

    ...

}

当我尝试从浏览器访问应用程序时，没有显示任何内容，也没有生成日志输出。
