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=" rel="external nofollow" rel="external nofollow" 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=" rel="external nofollow" rel="external nofollow" width:644px">     <% out.print(listdc.get(i)); %>     </a><span>     [06-29]</span>     </li>     <% } %>     </ul>    </div>
