通过jpa getResultList 获取查询到的内容

        String sql = "select * from  spatial_event ";

        Query query = em.createNativeQuery(sql);
//        query.setParameter(1, email);
//        query.setParameter(2, id);
        List a = query.getResultList();
        for (Object item : a) {
            Object[] obj = (Object[]) item;
            for(Object o:obj){
            if (o != null) {
                System.out.print(o.toString());
                System.out.print("   ");
            }
            }
            System.out.println();
        }
