spring - ModelAndView object.addAttribute() equivalent to request.setAttribute

Question

Just a clarification. Is ModelAndView object.addAttribute() equivalent to request.setAttribute. I went through a Spring MVC example the author added an attribute with ModelAndView object.addAttribute(), then in the jsp retrieved it with request.getAttribute().

I tried the same example, it worked for me. Any thoughts on this?

Answer 1

ModelAndView#addObject(key,value)将属性放在request范围内。
