如何在Struts2中从乘法无线电接收值

Question

I am developing an online exam system that mainly include multiply choice. 我正在开发一个主要包括多项选择的在线考试系统。

I used <input type='radio'/> to show some options in form. 我使用<input type='radio'/>来显示一些选项。 But I don't know how to receive the lots of options when click the button 'submit'. 但是我不知道如何在单击“提交”按钮时接收大量选项。
The datas from database have almost 100 items, and I have set pagination in show_questions_info.jsp , now every page show 3 questions and every question has 7 options. 来自数据库的数据几乎有100项，我在show_questions_info.jsp中设置了分页，现在每个页面显示3个问题，每个问题有7个选项。
I want to use Action to receive value if it can be done. 我想使用Action来获得价值（如果可以做到的话）。 The <s:property value="question_code" /> is question number. <s:property value="question_code" />是问题编号。

show_questions_info.jsp show_questions_info.jsp

 <%@ taglib prefix="s" uri="/struts-tags" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> <form action=""> <s:iterator value="questionInfoBeanList" > <table> <tr> <td><s:property value="question_code" /></td> <td><s:property value="content" /></td> </tr> </table> <table> <tr> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_A" />" id="1"> <lable for="1"><s:property value="op_type_A" /></lable> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_B" />" id="2"> <lable for="2"><s:property value="op_type_B" /></lable> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_C" />" id="3"> <lable for="3"><s:property value="op_type_C" /></lable> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_D" />" id="4"> <lable for="4"><s:property value="op_type_D" /></lable> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_E" />" id="5"> <lable for="5"><s:property value="op_type_E" /></lable> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_F" />" id="6"> <lable for="6"><s:property value="op_type_F" /></lable> <input type="radio" name="<s:property value="question_code" />" value="<s:property value="op_type_G" />" id="7"> <lable for="7"><s:property value="op_type_G" /></lable> </tr> </table> </s:iterator> <s:submit value="提交" /> </form> </html>

Let's say you have reference of Questions List (displayed on JSP) in action class,simply iterate that list for questionCode(since in jsp <s:property value="question_code" /> is used for rendering q question) 假设您在动作类中引用了“问题列表”（显示在JSP上），只需对该列表进行迭代即可（因为jsp <s:property value="question_code" />用于呈现q问题）

   for(String questionCode:questionCodes){
     System.out.println(" For questionCode= "+questionCode+" selected option ="+request.getParameter(questionCode);):
    }
