Hibernate多对象查询

public void findUserInfoAll(Integer userId) {
              String sql = " select user, jfpoint from VoUser user,VoJfPoint jfpoint where user.id = jfpoint.userId and user.id = " + userId;
              EntityManager em = JPAUtil.currentSession();//获取session
              Query query = em.createQuery(sql);
              List list = query.getResultList();
              Object[] ob = (Object[])list.get(0);
              VoUser user = (VoUser)ob[0];
              VoJfPoint point = (VoJfPoint)ob[1];
              //这样就可以获取到user,point中属性
       }
