将服务器端对象从一个JSP页面传递到另一个 [英] Passing server-side objects from one JSP page to another

问题描述

我知道我可以使用getParameter()传递客户端对象，但是我想知道如何像使用getParameter一样传递服务器端对象.我已经看过getAttribute，但是我需要在第一个JSP页面上使用setAttribute，然后在第二个页面上使用getAttribute.任何帮助将不胜感激.

I know that I can use the getParameter() to pass client-side objects, but I am wondering what to use to pass server-side objects like I do with the getParameter. I have seen the getAttribute but do I need to use the setAttribute on the first JSP page and then the getAttribute on the second page. Any help would be greatly appriciated.

推荐答案

• 如果从一页到另一页使用forward(jsp:foprward或RequestDispatcher)，请使用request.setAttribute(..)和request.getAttribute()，因为您属于同一请求
• 如果您正在使用redirect(通过response.sendRedirect())，请使用request.getSession().setAttribute(..)和request.getSession().getAttribute()
• If you are using forward (jsp:foprward or RequestDispatcher) from one page to another, then use request.setAttribute(..) and request.getAttribute(), because you are within the same request
• If you are using redirect (via response.sendRedirect()), then use request.getSession().setAttribute(..) and request.getSession().getAttribute()
