How can I trim spaces from request parameters in Spring MVC

Question

I am struggling to believe that my need to trim leading and trailing spaces from the query parameters is not a general requirement, and yet I cannot find anyone who has a good answer to its solution.

Of course, is there an easy way to customize, say, Spring WebDataBinderto trim all spaces from parameter values ​​before matching them with the target?

I would really like to know how other people handled this.
