MyBatis中调用MySQL存储过程

MyBatis文件：AssetMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.topnpl.web.asset.mapper.AssetMapper">
	<!-- 资产地图各种统计 -->
	<select id="getMapCharts" resultType="java.util.HashMap" statementType="CALLABLE" >
		{call MAP_CHARTS(
			#{type, jdbcType=INTEGER, mode=IN},
			#{locationId, jdbcType=INTEGER, mode=IN}
		)}
	</select>
</mapper>

存储过程：

CREATE DEFINER=`root`@`%` PROCEDURE `MAP_CHARTS`(IN `type` INT ( 1 ), IN `locationId` INT ( 15 ))
BEGIN

# 当前区名，当前区所在的市名
IF type = 1 or type =0 THEN
	SELECT 
		location_name AS countryName,
        parent_id AS parentId,
        (SELECT location_name FROM topnpl_location WHERE id = parentId) AS cityName
	FROM 
		topnpl_location 
	WHERE
		isdel = 0
        AND id = locationId;
END IF;

# 当前区市场均价
IF type = 2 or type = 0 THEN
	SELECT 
		market_price marketAvg
	FROM
		topnpl_market_avg_price
	WHERE
		year_and_month = DATE_FORMAT(CURDATE(), '%Y-%m')
		AND location_id = locationId;
END IF;

END
