org.springframework.web.servlet.support.RequestDataValueProcessor
A contract for inspecting and potentially modifying request data values such as URL query parameters or form field values before they are rendered by a view or before a redirect.
Implementations may use this contract for example as part of a solution to provide data integrity, confidentiality, protection against cross-site request forgery (CSRF), and others or for other tasks such as automatically adding a hidden field to all forms and URLs.
View technologies that support this contract can obtain an instance to delegate to via {@link RequestContext#getRequestDataValueProcessor()}. @author Rossen Stoyanchev @since 3.1
