1.將PageResultSet.java文件編譯成class文件，并放入你的Web
應(yīng)用程序的WEB-INF/classes/com/youngor/util目錄下，可以對包名做相應(yīng)修改。

2.在你的Action類中:
先從業(yè)務(wù)處理邏輯類中取出數(shù)據(jù)(ArrayList或Vector格式)
UserBO userBO=new UserBO();
Collection data=userBO.findUsers();//示例方法
再得到當(dāng)前頁curPage和每頁記錄數(shù)pageSize
int curPage = Integer.parseInt(request.getParameter(“cur_page“));
int pageSize=15;
然后生成PageResultSet對象
PageResultSet dataList = new PageResultSet(data, curPage, pageSize);
request.setAttribute("usersList", dataList );

3.在你的JSP頁面中:
   <%
          PageResultSet pageResultSet=(PageResultSet)request.getAttribute("usersList");
   ArrayList usersList=(ArrayList)pageResultSet.getData();
   for(int i=0;i<usersList.size();i++)
   {
            UserEO userEO=(UserEO)usersList.get(i);%>
      <tr>
        <td><a href="view_user.do?id=<%=userEO.getId()%>"><%=userEO.getUsername()%></a></td>
        <td><%=userEO.getName()%></td>
        <td><%=userEO.getPhoneNumber()%></td>
        <td><%=userEO.getEmailBox()%></td>
        <td><%=userEO.getAddress()%></td>
        <td><%=userEO.getPostcode()%></td>
        </tr>
    <%}%>
    </table></td>
  </tr>
</table>

<!-- 顯示分頁工具欄 -->

<%=pageResultSet.getToolBar("list_users.do")%>


注意：
1、如果你覺得分頁工具欄不能滿足你的要求，可以用PageResultSet類中的公共方法
first()、previous()、next()、last()定制自己的工具欄，并且，你還可以在PageResultSet中定義多個樣式的工具欄；
2、getToolBar(String url)方法接受帶查詢字符串的參數(shù)，比如“list_users.do?class_id=1“。
