jsp:使用request为页面添加静态数据。

一，在div中插入要显示的数据！

 1，以下是原网页插入数据代码：

<div>
  <ul class="list-content">
<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa.</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa.</a><span>[06-29]</span></li>
<ul>
<div>
<div>
<ul class="list-content">
<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>
  <li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa...</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa</a><span>[06-29]</span></li>
<li><a href="">aaaaaaaaaaaaaaaaaaa...</a><span>[06-29]</span></li>
<ul>
   </div>

2,在src中创建servlet类：

使用request.setAttribute发送数据

public static ArrayList<String> list;
    static{
        list=new ArrayList<String>();
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");    
　　    public static ArrayList<String> listdc;
    static{
        listdc=new ArrayList<String>();
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
        listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
    }
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
            request.setCharacterEncoding("UTF-8");
            response.setContentType("text/html");
            ArrayList<String>list=getData();
            
            request.setAttribute("new", list);
            request.setAttribute("dc", listdc);
            request.getRequestDispatcher("/page/default.jsp").forward(request, response);
    }

3，在需要插入数据的地方加入jsp脚本：

使用request.getAttribute接收数据

通过for循环打印数据

<div>
                                    <ul class="list-content">
                                     
                                           <%
                                               ArrayList<String> list =(ArrayList<String>)request.getAttribute("new");
                                               if(list!=null)
                                                   for(int i=0;i<list.size();i++){
                                           %>
                                                      <li>
                                                          <a href="" style="width:644px">
                                                            <%  out.print(list.get(i)); %>
                                                          </a><span>
                                                               [06-29]
                                                         </span>
                                                      </li>
                                           <%     }%>

                                    </ul>
                                </div>
                                <div>
                                    <ul class="list-content">
                                        <%ArrayList<String> listdc=(ArrayList<String>)request.getAttribute("dc");
                                                if(listdc!=null)
                                           for(int i=0;i<listdc.size();i++){
                                        %>
                                        <li>
                                        <a href="" style="width:644px">
                                        <% out.print(listdc.get(i)); %>
                                        </a><span>
                                        [06-29]</span>
                                        </li>
                                        <% } %>
                                    </ul>
                                </div>
