JPA调用存储过程

@Transactional
    public BasAccount findByAccount(String account) {
        System.out.println(account);
        Query q = em.createNativeQuery("{call QueryBasAccount(?)}",BasAccount.class);
        q.setParameter(1, account);
        List<BasAccount> list = q.getResultList();
        BasAccount ba = null;
        if(list.size()>0){
             ba = (BasAccount)q.getResultList().get(0);
        }
        return ba;
    }

语法：{call methodName(?)} Query .setParameter(1, param1);

　　   {call methodName(?，？)} Query .setParameter(1, param1);Query .setParameter(2, param2);
