Answer 1

it seems like if you are using the #Param annotation in your Mapper interface method. In that case you must remove the paramType attribute from the select tag.
Other possible explanation for the exception is that the type attribute is not a integer. If the real type is short, by example, you get the IllegalArgumentException.
