mybatis中用注解如何处理存储过程返回的多个结果集？

sql代码：

create procedure sptest.getnamesanditems()
reads sql data
dynamic result sets 2
BEGIN ATOMIC
  declare cur1 cursor for select * from sptest.names;
  declare cur2 cursor for select * from sptest.items;
  open cur1;
  open cur2;
END
go

<resultMap type="org.apache.ibatis.submitted.sptests.Name" id="nameResult">
    <result column="ID" property="id"/>
    <result column="FIRST_NAME" property="firstName"/>
    <result column="LAST_NAME" property="lastName"/>
  </resultMap>

  <resultMap type="org.apache.ibatis.submitted.sptests.Item" id="itemResult">
    <result column="ID" property="id"/>
    <result column="ITEM" property="item"/>
  </resultMap>

  <select id="getNamesAndItems" statementType="CALLABLE"
    resultMap="nameResult,itemResult">
    {call sptest.getnamesanditems()}
  </select>

@Test
    public void testGetNamesAndItems() throws SQLException {
        SqlSession sqlSession = sqlSessionFactory.openSession();
        try {
            SPMapper spMapper = sqlSession.getMapper(SPMapper.class);

            List<List<?>> results = spMapper.getNamesAndItems();
            assertEquals(2, results.size());
            assertEquals(4, results.get(0).size());
            assertEquals(3, results.get(1).size());
        } finally {
            sqlSession.close();
        }
    }
