How can I trim whitespace from request parameters in Spring MVC

Question

I'm struggling to believe that my need to trim leading and trailing whitespace from request parameters is not a common requirement, and yet I can't seem to find anyone who has a good answer to solving it.

Surely there is some simple way to configure, say, the Spring WebDataBinder to trim all whitespace from parameter values before mapping them to a target object?

I'd be really keen to know how other people have tackled this.

You can try registering a custom PropertyEditor in the WebDataBinder

 registerCustomEditor(String.class, propertyEditor)

Either create one or use the StringTrimmerEditor, and instantiate it with a set of whitespaces.
