Return HashMap in mybatis and use it as ModelAttribute in spring MVC

I want to display list of categories in my Jsp page using spring mvc @modelAttribute.

In my mapper.xml file is

<select id="selectAllCategories" resultMap="BaseResultMap">
  select id, name from categories  
</select>

In my Mapper.java class I have method

List<Map<String, String>> selectAllCategories();

I want to have a method like this:

Map<Integer, String>`selectAllCategories();

instead of List<Map<>>, is that possible?
