Where does the Spring Model that is passed to a JSP goes to?
jsp, spring-mvc
Solution
When you do something like `${attributename}`, JSP EL will check a variety of sources to find it, including the page and request contexts (in that order).
When your Spring controller returns a model (e.g. inside the `ModelAndView`), this model is decomposed by Spring's `AbstractView` class and inserted into the request context (this is the "magic" part), so that when your JSP EL expression refers to an item from the model, it's available to be used.
Problem
I've been reading docs and tutorials about spring (3.0), so I've learnt how to return a `ModelAndView` with the JSP name and a Map as the model. I've learnt also that in a JSP, if you want to access one key of that map you do `${attributename}` and so on. That's JSP EL. Now my questions: - What object of the page is the EL accessing? Is that `PageContext`? I tried to find those keys in `PageContext.getAttribute` but they are not there. - Whatever the object is, is it automatic that the things in the model go there? Feel free to add resources to clarify my ideas
