从Servlet的重定向 [英] Redirect from Servlet

问题描述

ObjectInputStream in = new ObjectInputStream((InputStream) request.getInputStream());
        List<Double> al=(List<Double>)in.readObject();
        in.close();
        for(int x=0;x<al.size();x++)
        {
            System.out.println("List");
            System.out.println(al.get(x));
        }
        System.out.println("going to demo.jsp");
        response.sendRedirect("demo.jsp");

我写一个客户端服务器程序。我从Android手机发送一个ArrayList，我能够接受的名单中还，但在那之后我想这个servlet重定向到demo.jsp，但它只是不会重定向。试着用的RequestDispatcher了。请帮忙。我在哪里去了？

I am writing a client server program. I am sending an arraylist from an android phone and i am able to receive the list also but after that I want the servlet to redirect to demo.jsp but it just wont redirect. Tried with requestdispatcher too. Please help. Where am I going wrong?

编辑：这是servlet code，它是在doPost方法

this is the servlet code and it is in the doPost method.

推荐答案

我张贴这个答案，因为一个得票最多使我误入歧途。从一个servlet重定向，你只需做到这一点：

I'm posting this answer because the one with the most votes led me astray. To redirect from a servlet, you simply do this:

response.sendRedirect("simpleList.do")

在这个特殊的问题，我想@MD正确地解释了为什么提问者是有他的问题，但由于这是当你搜索从Servlet的重定向谷歌的第一个结果，我认为有一个答案是很重要的帮助大多数人，而不仅仅是原来​​的提问者。

In this particular question, I think @M-D is correctly explaining why the asker is having his problem, but since this is the first result on google when you search for "Redirect from Servlet" I think it's important to have an answer that helps most people, not just the original asker.
