add MapValue annotation

[min1854]

I want to be able to define the value of the map in addition to the key of the map, Implemented through the MapValue annotation, And it doesn't affect the original MapKey annotation

#2865

public interface NoticeMapper {

  @MapKey("status")
  @MapValue("count")
  Map<Integer, Integer> groupStatus();


}

<mapper namespace="org.apache.ibatis.submitted.mapkey_value.NoticeMapper">


  <resultMap id="groupStatusMap" type="hashmap">
    <result column="count" javaType="Integer" property="count"/>
    <result column="status" javaType="Integer" property="status"/>
  </resultMap>


  <select id="groupStatus" resultMap="groupStatusMap">
  select count(*) as count , status
    from notice group by status
  </select>


</mapper>
