blocks|key|3766990|text|好吧，我找到了一个变通方法。或者，这也可能是底层Spring框架所做的一切。我只是在HttpServletRequest中自动连接并调用了setAttribute。似乎工作得很好。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3766991|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Well, I found a workaround. Or maybe it's all that the underlying Spring framework is doing anyway. I just autowired in the HttpServletRequest and called setAttribute. Seems to work fine.

I would not use the <code>@Autowired</code> on <code>HttpServletRequest</code> as it will confuse future developers working on the code of threadsafety. 

Instead you should use either a <code>@ModelAttribute</code> or an <code>Interceptor</code>.

<h3>@ModelAttribute</h3>

See:
<a href="http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/mvc.html#mvc-ann-modelattrib-method-args" rel="nofollow">http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/mvc.html#mvc-ann-modelattrib-method-args</a>

But you can do something like this and add this method to your controller:

<pre><code>@ModelAttribute
public preloadModel(HttpServletRequest request, ModelMap model) {
 //Add stuff to model.
}
</code></pre>

<h3>Interceptor</h3>

See: <a href="http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/mvc.html#mvc-handlermapping-interceptor" rel="nofollow">http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/mvc.html#mvc-handlermapping-interceptor</a>

<pre><code>public class PreloadModelInterceptor extends HandlerInterceptorAdapter {

 @Override
 public void postHandle(HttpServletRequest request, 
 HttpServletResponse response, 
 Object handler,
 ModelAndView modelAndView) throws Exception {
 // add model attibutes for your view to see but not your controller
 }
}
</code></pre>

Sorry about the title. I couldn't think of a better wording.

Is there any way to set the default Model that Spring will supply the page without first retrieving it as an argument in the @RequestMapping method?

I'm using aspects to take the return value of controller methods(returning the view) and insert it into the model, then rendering a different global view which then includes what I added into the model. This works fine on methods that request the Model as a parameter.

However, I also want to be able to catch all methods that don't explicitly request the model and still insert the return value into it (via @AfterReturning advice). Any ideas?

很抱歉标题有误。我想不出更好的措辞了。有没有办法设置Spring将提供页面的默认Model，而不首先在@RequestMapping方法中将其作为参数检索？我使用方面来获取控制器方法的返回值(返回视图)，并将其插入到模型中，然后呈现一个不同的全局视图，其中包括我添加到模型中的内容。这在将Model作为参数请求的方法上工...
