基于上面的分页，继续将Servlet也贴出来

import java.io.IOException;import java.sql.SQLException;import java.util.List;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;import com.gxa.bj.lg.model.UserInfo;import com.gxa.bj.lg.service.SerUserInfo;@WebServlet(name="page",urlPatterns="/page.do")public class PartPageServlet extends HttpServlet{    SerUserInfo serU = new SerUserInfo();    @Override    protected void doGet(HttpServletRequest req, HttpServletResponse resp)            throws ServletException, IOException {        HttpSession session = req.getSession();        String Index = req.getParameter("hf");         session.setAttribute("pageIndex", Index);        int pageIndex = Integer.parseInt(Index);        try {            List<UserInfo> list = serU.getListPage(pageIndex);            req.setAttribute("list", list);            req.getRequestDispatcher("partPage.jsp").forward(req, resp);        } catch (SQLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    @Override    protected void doPost(HttpServletRequest req, HttpServletResponse resp)            throws ServletException, IOException {        doGet(req,resp);    }}

下面是测试的jsp页面（用了jstl标签）

<body>  <script>    function showPrve() {        if(document.getElementById("hf").value=="") {            document.getElementById("hf").value = 1;        }else {            var pageIndex = parseInt(document.getElementById("hf").value)-1;            document.getElementById("hf").value = pageIndex;        }        document.form1.submit();    }    function showNext() {        if(document.getElementById("hf").value == "") {            document.getElementById("hf").value = 1;        }else {            var pageIndex = parseInt(document.getElementById("hf").value)+1;            document.getElementById("hf").value = pageIndex;        }        document.form1.submit();    }  </script>  <form method="post" name="form1" action="page.do">    <table>        <tr>            <td>用户名</td>            <td>邮箱</td>        </tr>        <c:forEach items="${requestScope.list }" var="user">            <tr>                <td>                    ${user.getUserName()}                </td>                <td>                    ${user.getUserEmail() }                </td>            </tr>        </c:forEach>        <input type="button" value="上一页" onclick="showPrve()" id="prve"/>        <input type="button" value="下一页" onclick="showNext()" id="next"/>        <input type="hidden" value="${sessionScope.pageIndex }" name = "hf" id="hf"/>    </table>  </form> </body>
