推荐答案

您应将sitemesh(任何模板引擎可能是图块)与HandlerInterceptorAdapter结合使用.下面是示例代码，

you should use sitemesh (any templating engine may be tiles) in conjunction with HandlerInterceptorAdapter. Below is sample code,

@Component
public class MenuHandler extends HandlerInterceptorAdapter {

@Autowired
private MenuService menuService;

@Override
public void postHandle(HttpServletRequest request,
        HttpServletResponse response, Object handler,
        ModelAndView modelAndView) throws Exception {
     load and set menu items in request attributes (session can also be used).
    }
}

并将请求/会话属性用于通用菜单jsp.

and use request/session attribute to common menu jsp.
