I looked all over but couldn't find one, but it would be nice if there was a parameterized single column row mapper in Spring. There is one available for the non-java 5 code base, but there isn't one with use for generics. I've written one that simply wraps the SingleColumnRowMapper but I thought framework should contain such a class.
I can provide my class if you like but it was very easy to implement (~35 lines of code).
