How to send parameter from controller in other controller in springMVC?

Question

In post method I did generate an object and try to send him into another Controller:

@PostMapping("/main")
    public ModelAndView makesQuery(
            @RequestParam String query
    ){
//   create new explorer if
        Explorer explorer = explorerService.createByQuery(query);

//   determine status of explorer
        StatusEnum q = StatusEnum.getEnum(explorer.getStatus().getStatusName());

        String http = q == StatusEnum.FINISHED ?
                "redirect:/show" : "redirect:/parsing";

        ModelAndView modelAndView = new ModelAndView(http);
        modelAndView.addObject("explorer", explorer);

        return modelAndView;
    }

in next method I try to get object Explorer:

@GetMapping("/parsing")
public ModelAndView makesQuery(
        @ModelAttribute Explorer explorer
) {
    ModelAndView modelAndView = new ModelAndView("search");
    modelAndView.addObject("explorer", explorer);
    return modelAndView;
}

But have next error:

Error resolving template "parsing", template might not exist or might not be accessible by any of the configured Template Resolvers

When i change annotation for Explorer from @ModelAttribute to @RequestParam:

@GetMapping("/parsing")
public ModelAndView makesQuery(
        @RequestParam Explorer explorer
) {......

I did have error in browser:

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Wed Aug 15 14:15:52 EEST 2018 There was an unexpected error (type=Bad Request, status=400). Required Explorer parameter 'explorer' is not present

PS search.html file not have any logic in body - only string "test".

You can save the explore object in session.

HttpSession session = request.getSession(true); session.setAttribute( "explorer", explorer)

And to get

@GetMapping("/parsing") public ModelAndView makesQuery(HttpServletRequest request..) HttpSession session = request.getSession(); Explore explore = session.getAttribute("exolorer")
