我安装了最新的Grails
PayPal插件(0.6.4)
,出现以下错误:

Problems occurred (un)installing plugins. See details for more information
------System.out:-----------

我将
notify()
重命名为
notifyPaypal()
=>

但该插件似乎干扰了springSecurity,因为如果我尝试登录,会出现以下错误:

| Error 2012-02-05 21:42:07,245 ["http-bio-8080"-exec-8] ERROR [/projectname].[default]  - Servlet.service() for servlet [default] in context with path [/projectname] threw exception
Message: The specified user domain class 'Person' is not a domain class

如何修复它?

请注意,自0.6.4以来已经发布了两个版本,现在它的行为与您要求的关于“notify()”方法的行为相同(可能要感谢您的报告)
