mysql存储过程怎么调用？怎么把值放入map?我写的mybatis调用mysql

根据网上材料写的mybatis 调用mysql储存过程报错
这是测试类里面的

try {
     String resource = "com/qipei/mapper/DdmlMapper.xml";
     Reader reader= Resources.getResourceAsReader(resource);
    SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(reader);

     SqlSession session = sessionFactory.openSession();

     Map<String, Object> parms = new HashMap<String, Object>();  
     parms.put("CZDX", "DDML");
     parms.put("CJDM", "000001");
     parms.put("RQ", "20161213"); 
     String user1 = (String) session.selectOne("com.qipei.dao.IDdmlDao.getZyh", parms);
     System.out.println(parms.get("CZDX"));  
     System.out.println(parms.get("oCursor"));  
     System.out.println(user1);  
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} 

  报错
    Exception in thread "main" org.apache.ibatis.exceptions.PersistenceExceptio n:

配置map文件，将查询到的值放入map

<resultMap type="com.qipei.bean.Ddml" id="ddml">
    <id column="zyh" property="zyh" />
  </resultMap>
  <parameterMap type="hashmap" id="zyhMap">
    <parameter property="CZDX" jdbcType="VARCHAR" mode="IN" />
    <parameter property="CJDM" jdbcType="VARCHAR" mode="IN" />
    <parameter property="RQ" jdbcType="VARCHAR" mode="IN" />
    <parameter property="oCursor" jdbcType="VARCHAR" mode="OUT"/>
  </parameterMap>
   <select id="getZyh" statementType="CALLABLE" parameterMap="zyhMa p" >
         {call getzyh(?,?,?,?)}
    </select>
