当根目录 / 通过拦截器访问。首先，我们必须创建自己的控制器，为我们的登录页创建模型。无法将其Map到 / 或者 /home 因为这些Map已经定义。

public class CustomHomeController {

    @RequestMapping(value = { "/customHome" }, method = RequestMethod.GET)
    public String landingPage(ModelMap model) {
        fill(model);

        // Here "home" refers to a view name e.g. as Freemarker template
        return "home";
    }
}

然后，我们就可以拦截 / 并使用 AsyncHandlerInterceptor :

public class HomeInterceptor extends HandlerInterceptorAdapter {

    /**The controller instance returning the view for the landing page. */
    private final CustomHomeController customHomeController;

    @Autowired
    public HomeInterceptor(CustomHomeController customHomeController) {
        this.customHomeController = customHomeController;
    }

    /**
     * Swaps the {@link ModelAndView} to the one returned by
     * {@link CustomHomeController#landingPage(ModelMap) }.
     * The controller performs no checking if the model and view is
     * actually one for the landing page. The correct setup
     * has to be ensured by the configuration.
     */
    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
        // Manually call the Controller custom home
        // If necessary, also request can be forwarded
        customHomeController.landingPage(modelAndView.getModelMap());
    }
}

在配置中，将注入处理程序：

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/"/>
        <bean class="com.example.HomeInterceptor"/>
    </mvc:interceptor>
</mvc:interceptors>

这需要 xmlns:mvc="http://www.springframework.org/schema/mvc" 以及 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd 在架构定义中。
如果需要，可以禁用原始 /home 通过安全配置Map。
