public class ViewNameMethodReturnValueHandler extends Object implements org.springframework.web.method.support.HandlerMethodReturnValueHandler
void and String interpreting
them as view name reference.
A null return value, either due to a void return type or
as the actual return value is left as-is allowing the configured
RequestToViewNameTranslator to select a view name by convention.
A String return value can be interpreted in more than one ways depending
on the presence of annotations like @ModelAttribute or
@ResponseBody. Therefore this handler should be configured after
the handlers that support these annotations.

public void setRedirectPatterns(String... redirectPatterns)
PatternMatchUtils.simpleMatch(java.lang.String, java.lang.String)) to use in order to recognize
custom redirect prefixes in addition to "redirect:".
Note that simply configuring this property will not make a custom redirect prefix work. There must be a custom View that recognizes the prefix as well.
