You can user a Spring-MVC Interceptor

public class TrimInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        Enumeration<String> e = request.getParameterNames();
        while(e.hasMoreElements()) {
            String parameterName = e.nextElement();

            request.setParameter(parameterName, request.getParameter(parameterName).trim());
        }

        return true;
    }

And set up your HandlerMapping interceptors property

<bean id="interceptorTrim" class="br.com.view.interceptor.TrimInterceptor"/>
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" p:interceptors-ref="interceptorTrim"/>
}

Or use a Servlet Filter
