我发现了一个与我的问题相关的问题here，但没有任何人回复。我遇到了同样的问题。
我正在Spring和Hibernate中实现RBAC（基于角色的访问控制）。要获得所有权限我正在使用以下查询
String query = "SELECT P.permid, P.permname , U.loginname, U.userid, R.rolename"
+ " FROM net.lynncom.fieldforce.persistence.model.Permission AS P \n"
+ " INNER JOIN net.lynncom.fieldforce.persistence.model.Rolepermission AS RP ON P.permid = RP.permid\n"
+ " INNER JOIN net.lynncom.fieldforce.persistence.model.Role AS R ON R.roleid=RP.roleid\n"
+ " INNER JOIN net.lynncom.fieldforce.persistence.model.Userrole AS UR ON UR.roleid=R.roleid\n"
+ " INNER JOIN net.lynncom.fieldforce.persistence.model.Usercredential AS U ON u.userid=UR.userid\n"
+ " WHERE U.loginname='akash' AND RP.deleted=false AND UR.deleted= false";
我的Java代码就是那样
List<Object> results=getCurrentSession().createQuery(query).list();
我收到以下错误：
type Exception report

description The server encountered an internal error that prevented it from fulfilling this request.
