SpringMVC从一个controller跳转到另一个controller

return "redirect:……路径……";

    @RequestMapping(value = "/index", method = RequestMethod.GET)

    public String index(ModelMap model) {

        Admin admin = adminService.getCurrent();

        if(admin.getSeller()!=null)

        {

            return "redirect:/admin/seller/order/list";

        }

        model.addAttribute("systemName", systemName);

        model.addAttribute("systemVersion", systemVersion);

        model.addAttribute("systemDescription", systemDescription);

        model.addAttribute("systemShowPowered", systemShowPowered);

        model.addAttribute("javaVersion", System.getProperty("java.version"));

        model.addAttribute("javaHome", System.getProperty("java.home"));

        model.addAttribute("osName", System.getProperty("os.name"));

        model.addAttribute("osArch", System.getProperty("os.arch"));

        model.addAttribute("serverInfo", servletContext.getServerInfo());

        model.addAttribute("servletVersion", servletContext.getMajorVersion() + "." + servletContext.getMinorVersion());

        model.addAttribute("waitingPaymentOrderCount", orderService.waitingPaymentCount(null));

        model.addAttribute("waitingShippingOrderCount", orderService.waitingShippingCount(null));

        model.addAttribute("marketableProductCount", productService.count(null, true, null, null, false, null, null));

        model.addAttribute("notMarketableProductCount", productService.count(null, false, null, null, false, null, null));

        model.addAttribute("stockAlertProductCount", productService.count(null, null, null, null, false, null, true));

        model.addAttribute("outOfStockProductCount", productService.count(null, null, null, null, false, true, null));

        model.addAttribute("memberCount", memberService.count());

        model.addAttribute("unreadMessageCount", messageService.count(null, false));
