mybatis的xml映射文件

1，在进行统计查询时候，不想写映射的实体类，这时候设置返回的resultType类型是map

   <select id="getMap" resultType="java.util.Map" parameterType="java.util.Map" >

     select

     count(*) as totalTimes ,sum(brushLong) as totalSecond

     from xxxx   where toothId = #{toothId,jdbcType=BIGINT}

     and date(brushDate) = DATE_FORMAT(#{date,jdbcType=TIMESTAMP},'%Y-%m-%d') ;

  </select>

2 , 调用方法

	Map<String,Object> parms2 = new HashMap<String,Object>();

	parms2.put("toothId", 10000);

	parms2.put("date","2018-08-08");

	Map object = (Map) toothDao.getMap(parms2);

	String  totalTimes = 0;

	if(object.containsKey("totalTimes")){

		totalTimes =object.get("totalTimes").toString();

	}
