我想让用户回答一系列问题，然后在最后告诉他们自己的分数

到目前为止，我已经得到了这个

许多。JSP，每个问题都写在里面。每页都有一个“下一步”按钮，将他们带到下一个问题。最后一个问题链接到一个名为“结果”的页面。jsp，它需要计算出他们的答案是正确的还是错误的，然后告诉他们他们的分数

我是库恩。jsp

<form action="/HelloSpring/results" method="post">

    <p> What is the correct wrapper class for the primitive int? </p>
    <input type="radio" name="radios" value="Int">Int<br>
    <input type="radio" name="radios" value="Enum">Enum<br>
    <input type="radio" name="radios" value="integer1">integer<br>
    <input type="radio" name="radios" value="Integer2">Integer<br>
    <input type="text" name="elc" autocomplete="off" >name<br>
             <input type="submit" value="Next" >

</form>
<FORM><INPUT Type="button" VALUE="Back" onClick="history.go(-1);return true;"></FORM>

</body>
</html>

一旦点击，你就会得到结果。jsp

<body>
<h2>Result</h2>

<p>Good day ${elc}, you scored ${a} </p>

<c:forEach items="${results}" var="total" >
    ${total};
    ${Score};
    ${score};
</c:forEach>

<section>
<p>Total score: ${total}</p>
</section>

</body>
</html>

这是网络控制器。java文件，该文件应处理最后一个问题的结果（如上所示）。它运行一个if语句，然后根据哪个if“运行”，它将向hashmap添加一个0或1。在某个时刻，我会打印出哈希映射的总数，以显示他们的分数，并添加其他问题的请求映射。我只想让第一个开始工作

 @RequestMapping(value = "/results", method = RequestMethod.POST)
        public String results(Model model, HttpSession session, HttpServletRequest request, @RequestParam String elc) {

                Object map2 = session.getAttribute("map");
                HashMap<String, Integer> map = (HashMap<String, Integer>) map2;

                request.getSession().setAttribute("score", "total");

                if(request.getParameter("radios") != null) {
                if(request.getParameter("radios").equals("Int")) {
                    model.addAttribute("Score", 0);
                    System.out.println("Int selected as your answer");
                }
                else if(request.getParameter("radios").equals("Enum")) {
                    model.addAttribute("Score", 0);
                    System.out.println("Enum selected as your answer");
                }
                else if(request.getParameter("radios").equals("integer1")) {
                    model.addAttribute("Score", 0);
                    System.out.println("integer was selected as your answer");
                }
                else {
                    System.out.println("Integer was selected as your answer");
                    model.addAttribute("Score", 1);
                }

            }
                   return "results";
        }
