MyBatis uses @MapKey annotation to receive multiple query records into Map

maper.xml

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

java dao code

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

The result returned is
{1={name:jasion,sex:1},2={name:jack,sex=1}}
