Class RequestUtils

  org.springframework.web.bind.RequestUtils

Deprecated. as of Spring 2.0: use ServletRequestUtils instead

public abstract class RequestUtils
extends Object
extends Object

Parameter extraction methods, for an approach distinct from data binding, in which parameters of specific types are required.

This approach is very useful for simple submissions, where binding request parameters to a command object would be overkill.
