DAO does not write interface, write implementation class directly

 Public List<dept> Tree (string hql, string par) {        = gethibernatetemplate (). Getsessionfactory ()                . Getcurrentsession ();         New ArrayList ();         if (par.length () = = 0)            {= session.createquery (hql). List ()        ; Else {            = Session.createquery (HQL). setString (0, par). List ();        }         return list;    }

Service Implementation Class

 Public     List<dept> Tree (Dept Dept) {        = "";         = "";         if (Dept.getid () =null | | dept.getid (). Trim (). Equals ("")) {            = "from Dept d where D.dept is null" c12>;        } Else {            = "from Dept d where d.dept.id =?" ;             = Dept.getid ();        }                 return Deptdao.tree (hql, par);    }
