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，我得到一个以这个错误开头的长堆栈跟踪，然后或多或少地重复它大约400行：

我认为相关部分是这样的：
org.hibernate.MappingException: property [sponsoringManager] not found on entity [com.mycompany.myapp.ManagerDelegate]
这是ManagerDelegate域类的代码，它是多对多的连接类：
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确实包含一个sponsoringManager属性，该属性在belongsTo语句中声明。这在Grails 1.3.9中完美运行。
这是User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，不会显示任何内容，也不会生成日志输出。
