Spring request parameter handling

Question

I am developing a questionnaire application with spring MVC. I have the form with 30 questions and 30 radio buttons. When the user submit the form I have to get the user answers from the request I have three decision.

1. Inside a loop call request.getParameter() 30 times

2. :

   public class QuestionBank {
   
       private List<Question>  question;
   ....
   }
   
   
        <form:form action="question.html" modelAttribute="QuestionList" >
   
           <c:forEach items="${QuestionList.question}" var="q" varStatus="status">
            ...
                       <input type="radio" name="question[${status.index}].useranswer" value="1" />
                       <input type="radio" name="question[${status.index}].useranswer" value="2" />
                   ...
                   </div>
           </c:forEach>
   
                   <input type="submit" value="submit" />
            </form:form>
   

   process the list inside controller

3. Use the Ajax submission (create a json format of answers)

From this three Which the recommended and fast processing ?

Answer 1

IMHO It's not a good idea that we search for the fastest way to doing something ! I think we should see what we want to do , the fastest way is relative to our issue ! If we just want to calculate the "time of processing" , it can not help us to find the better solution. Request , ajax or spring are 3 way to sending request to server. In your problem , I think it's better to use the object mapping with spring , because you are really sending a FORM and maybe you want to validate it and it's better spring do it for you, surely reloading all content of the page or a part of it is not the problem .
