MyBatis查询结果在HashMap中？

Question

For the below query,

 SELECT 
     MSGS.MSGTYPE,
     count(*) as NOOFRECORDS 
 FROM 
     SCHEMA.MESSAGES MSGS
 GROUP BY 
     MSGS.MSGTYPE

What would be the equivalent in MyBatis mapper so that I can get a Result as a HashMap with MSGS.MSGTYPE as the key and NOOFRECORDS as the value ?

<select id="selectAllCategories" resultType="hashmap">
 select id, name from categories  
</select>
