spring mvc：在非@Controller 端点上应用@ModelAttribute

Question

我已阅读 了解如何在全局范围内向模型注入参数。我的理解是否正确，这种方法不会涵盖由例如呈现的视图<mvc:view-controller>，或 form-login 自定义登录页面？

如果是这样，有没有办法扩展这种机制以包括所有视图？

谢谢

最终使用 Interceptor, as laid-out in this reply. Registered interceptor to intercept all non-resource endpoints (using mvc:exclude-mapping).

public class HandlerInterceptor extends HandlerInterceptorAdapter {
@Override
public void postHandle(HttpServletRequest request,
                       HttpServletResponse response,
                       Object handler,
                       ModelAndView modelAndView) throws Exception {
    if (modelAndView == null)
        return;
    modelAndView.addObject("foo", "bar");
}
