mybatis調用存儲過程

mysql 存儲過程能夠經過select 能夠直接返回結果集

咱們寫兩個存儲過程一個有參數，另外一個沒有參數

--無參數
DELIMITER $$

DROP PROCEDURE IF EXISTS `pro1`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `pro1`()
BEGIN
  select * from course_info;
END$$

DELIMITER ;
-- 有參數
DELIMITER $$

DROP PROCEDURE IF EXISTS `pro2`$$

CREATE DEFINER=`root`@`localhost` PROCEDURE `pro2`(in idParam int)
BEGIN
  select * from course_info where id = idParam;
END$$

DELIMITER ;

course_info 表數據

CREATE TABLE `course_info` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `cname` varchar(255) DEFAULT '',
  `caddress` varchar(255) DEFAULT '',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8

mybatis代碼調用存儲過程

    

<resultMap id="BaseResultMap" type="com.dlh.enty.courseInfo" >
    <!--

    -->
    <id column="id" property="id" jdbcType="INTEGER" />
    <result column="cname" property="cname" jdbcType="VARCHAR" />
    <result column="caddress" property="caddress" jdbcType="VARCHAR" />
  </resultMap>

 --沒有參數傳入
 <select id="queryByProcedure" resultMap="BaseResultMap" statementType="CALLABLE">
  {call pro1()}
  </select>
 --有參數傳入 相對於上面調用沒有參數的存儲過程 多了個parameterType 接口層是把相關參數放到一個map裏面
    <select id="queryByProcedureByMap" parameterType="java.util.Map" resultMap="BaseResultMap" statementType="CALLABLE">

    {call pro2(  
    #{idParam,jdbcType=VARCHAR,mode=IN})}  
 
  </select>
