use it like this

```java
public interface NoticeMapper {

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


}
```


```xml
<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>
