jsp 使用request为页面添加静态数据的实例

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 ArrayListString> list;
 static{
 list=new ArrayListString>();
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee");
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
 listdc.add("dcrewrwe3eeeeeeeeeeeeeeeee"); 
　　 public static ArrayListString> listdc;
 static{
 listdc=new ArrayListString>();
 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");
  ArrayListString>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">
     
      %
      ArrayListString> list =(ArrayListString>)request.getAttribute("new");
      if(list!=null)
       for(int i=0;ilist.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">
     %ArrayListString> listdc=(ArrayListString>)request.getAttribute("dc");
      if(listdc!=null)
      for(int i=0;ilistdc.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>
