The betweern difference returns a plain modelandview and returns a redirection and redirection model

Question

I just found out Spring MVC web stream. I am confused by this:

return new ModelAndView("test");
return new ModelAndView("redirect:test");

Is call forwarding the same as response.sendRedirect()? And I'm just checking the Spring link, in fact, return new RedirectView()doing the same thing as response.sendRedirect(). So what's the difference between the three?

Answer 1

ModelAndView ( "test" ) ModelAndView ( ": " ) . RequestDispatcher request.sendRedirect() requestdispatcher sendredirect,

": " HttpServletResponse.sendRedirect(), RedirectView .
IMO, API , , , - -.

RedirectView HttpServletResponse.sendRedirect(), HTTP. URI URL- . , / , .

, spring MVC, . . ,

public String doSomething(Model model){
    return "test";
}
public ModelAndView i_am_similar_to_doSomething(){
    return new ModelAndView("test");
}

//You can guess that you can do the same thing with redirect.
