SpringMVC中Controller跳转到另一个Controller方法

    1、直接Redirect后加 Controller/Action
    Response.Redirect("/User/Edit");
    // return Redirect("/User/Edit");
    return RedirectToAction("about","Home");
    Response.Redirect("/User/Edit");

    2、直接return后加 Controller/Action
    return Redirect("/User/Edit"); 

    3、RedirectToAction方法，直接跳到一个action
    return RedirectToAction("edit"); 

    4、跳转的页并不在该Controller中
    return RedirectToAction("about","Home"); 

    5. redirect跳转
    String url = "redirect:/test.do";
    mav = new ModelAndView(url);
