我有一个从txt文件RegistrationFormBean()读取的对象数组列表;是元素类型

    public List getuserList() throws IOException{

            InputStream input = new FileInputStream("log.txt");

                int i=0;

                String temp[]=new String[5];

                                          tmp= new RegistrationFormBean();
                BufferedReader in = new BufferedReader(new FileReader("log.txt"));

                while ((str = in.readLine()) != null) {

                              StringTokenizer st = new StringTokenizer(str,"\t\t");

                    while(st.hasMoreElements()){
                    temp[i]=st.nextElement().toString();
                                                }

                                                   tmp.setName(temp[0]);
                    tmp.setCognome(temp[1]);
                    tmp.setCitta(temp[4]);
                    tmp.setDdnascita(temp[2]);
                    tmp.setCodfisc(temp[3]);

                    userList.add(tmp);
                                        }
                in.close();

    return userList;
}
这是一个jsp页面,它应该迭代返回的arraylist并打印arraylist中每个元素的属性

所以我想知道如何访问下一个元素的元素,假设属性是element.name element.cognome element.ddnascita(元素的属性),我应该在读取txt文件的类中定义一些getter吗? 我应该在jsp页面中引用元素类型吗

请注意,对于我编写的代码,我只打印了第一列,其中包含“citta”,tmp中的“citta”是元素的最后一个属性, 我还进行了调试,正确加载了列表,因此我认为问题出在jsp页面上。

您可以使用
标记访问嵌套属性。 要使用它,您需要在JSP页面中添加标记库:

<%@ taglib uri="/tags/struts-nested" prefix="nested"%>

thx这就是我想要的,在apache页面旁边,我在哪里可以找到一些关于定制struts标签的适当参考?
<nested:nest property="userList">
    <!-- 'name' is just plain String, does not need a nested iteration --> 
    <nested:write property="name"/> 

    <!-- but 'cognome' has some inner properties, we are interested in exploring -->
    <nested:iterate property="cognome">
         <nested:write property="somePropertyOfCognome"/>
    </nested:iterate>

</nested:nest>
