我不明白错误。谁能解决这个问题?

i did not understand the error. Can anyone solve this?

当我登录我的应用程序时出现此错误。
有人可以解释一下吗??

错误:-

Error 500: Internal Server Error
URI/BookForAsia/Classorg.hibernate.hql.internal.ast.QuerySyntaxException
Message securityUser is not mapped
Around line 101 of grails-app\realms\org\ng\securityDbRealm.groovy

101: def results = SecurityUser.executeQuery("select distinct p from securityUser 
 as user join user.permissions as p where user.username = '$principal'")    

也许您必须在 HQL 查询中将 securityUser 大写,使其变为 SecurityUser?
