I could do it that way... I could also put a type handler on every single string column I get back from the database...
The reason I don't really want to do either is because I've got a lot of tables and a lot of POJOs, and doing either is a pain in the neck. Also, I normally write my domain objects to an interface, and you can't specify that sort of behaviour in an interface. And sometimes I return values in HashMaps, and I don't really want to extend HashMap just so I can trim some strings. For now, in the places where it's causing me problems, I've used the type handler/resultmap solution - it's less invasive, even if it's very verbose.
