=============操作========

增加

                ComposeIdPK composeIdPK=new ComposeIdPK ();
                composeIdPK.setAuthId(authId);
                composeIdPK.setRoleId(roleId());
                RoleAuth roleAuth=new RoleAuth();
                roleAuth.setComposeIdPK(composeIdPK);
                roleAuthManager.save(roleAuth);

查询

        Session session = getSession();
        List<RoleAuth> roleAuthList = session.createCriteria(RoleAuth.class).add(Restrictions.eq("composeIdPK.roleId", roleId)).list();
