MyBatis使用@MapKey注解接收多个查询记录到Map中

maper.xml

<select id="getUsers" resultType="java.util.Map"  parameterType="java.util.Map">
select id,name,sex from t_user
</select>

java dao代码

@MapKey("id")
public Map<Integer,Map<String,Object>>getUsers(Map<String,Object>param);

返回的结果是
{1={name:jasion,sex:1},2={name:jack,sex=1}}
