Answer 1

To get all parameters at once try this:

public ModelAndView postResultPage(@RequestParam MultiValueMap params)

This feature is described in the @RequestParam java doc (3. Paragraph):

Annotation which indicates that a method parameter should be bound to a web request parameter. Supported for annotated handler methods in Servlet and Portlet environments.

If the method parameter type is Map and a request parameter name is specified, then the request parameter value is converted to a Map assuming an appropriate conversion strategy is available.

If the method parameter is Map or MultiValueMap and a parameter name is not specified, then the map parameter is populated with all request parameter names and values.
