向ModelAndView添加属性 [英] Adding an attribute to a ModelAndView

问题描述

我正在编写一个HandlerInterceptor，需要将某个会话范围的bean插入到Model中. postHandle的签名如下:

I'm writing a HandlerInterceptor that needs to insert a certain session-scoped bean into the Model. postHandle's signature looks like this:

public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception

ModelAndView没有addAttribute功能.如何在ModelAndView中添加属性，以便可以在视图内部使用request.getAttribute访问它?

ModelAndView has no addAttribute function. How can I add an attribute to a ModelAndView so that I can access it with request.getAttribute inside my views?

推荐答案

使用

还有其他一些间接方式，通过modelAndView.getModel()或modelAndView.getModelMap().但是您应该更喜欢addObject(..)版本.实际上，它会调用getModelMap().addAttribute(..)

There are also some other indirect ways, through modelAndView.getModel() or modelAndView.getModelMap(). But you should prefer the addObject(..) version. In fact it invokes getModelMap().addAttribute(..)
