<select id="keyEquipmentShiftAutomatedModelData" parameterType="java.util.Map" resultType="java.util.Map"> SELECT ID, SUM(VALUE1 + VALUE2) Total FROM tableName GROUP BY ID </select>

Returns below result in sql 
ID, Total 
1 (null) 
But when returned in Map result in myBatis returns {ID=1} where as Total is missing. How to get the column with null into the result set as well something like this {ID=1,Total=null} or something like this {ID=1,Total=""}

Adding
<settings>
<setting name="callSettersOnNulls" value="true"/>
</settings>

mybatis-config.xml fixes the issue if using mybatis 3.2 + version
