一、POM.xml
<dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>4.1.6</version> </dependency>
踩坑:使用5.0以上的版本报错,能力有限还未理解什么问题,有大牛可以给评论下感激不尽。
二、Spring-*.xml
<!-- 配置分页插件 --> <property name="plugins"> <array> <bean class="com.github.pagehelper.PageHelper"> <property name="properties"> <value> <!-- 你使用的数据库类型 --> dialect=mysql reasonable=true </value> </property> </bean> </array> </property>
三、Controller
@Controller @RequestMapping(value = "/uu", method = { RequestMethod.GET, RequestMethod.POST }) public class UserTest { @Autowired private AdminUserService auc; @RequestMapping("/userList") public String userList(@RequestParam(required=true,defaultValue="1") Integer page,HttpServletRequest request,Model model){ //page默认值是1,pageSize默认是10,我写的是2 意思是从第1页开始,每页显示2条记录。 PageHelper.startPage(page, 2); List<AdminUser> userList = auc.selectByList(); System.out.println(userList); PageInfo<AdminUser> p=new PageInfo<AdminUser>(userList); model.addAttribute("page", p); model.addAttribute("userList",userList); return "/admin/test.jsp"; } }
导入
import java.util.List; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import com.github.pagehelper.PageHelper; import com.github.pagehelper.PageInfo;
四、Service
List<AdminUser> selectByList();
五、ServiceImpl
@Override public List<AdminUser> selectByList() { // TODO Auto-generated method stub return adminUserMapper.selectByList(); }
六、Dao
List<AdminUser> selectByList();
七、Mapper.xml
<select id="selectByList" resultType="com.*.*.entity.AdminUser"> select * from adminuser T </select>
resultType="com.*.*.entity.AdminUser
上面是你的实体类
八、Jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; %> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'test.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- 最新版本的 Bootstrap 核心 CSS 文件 --> <link rel="stylesheet" href="https ://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous"> <!-- 可选的 Bootstrap 主题文件(一般不用引入) --> <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous"> <!-- 最新的 Bootstrap 核心 JavaScript 文件 --> <script src="https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script> </head> <body> <center> <table width="200" border="1" class="table table-striped"> <tr> <th scope="col">序号</th> <th scope="col">ID</th> <th scope="col">姓名</th> <th scope="col">密码</th> <th scope="col">年龄</th> </tr> <c:forEach begin="0" step="1" items="${userList}" var="list" varStatus="userlist"> <tr> <td></td> <td>${list.userId}</td> <td>${list.userName}</td> <td>${list.userPassword}</td> <td></td> </tr> </c:forEach> </table> <p>当前表格共${page.pages}页、${page.total}条记录</p> <nav aria-label="Page navigation"> <ul class="pagination"> <li> <a href="<%=request.getContextPath()%>/uu/userList?page=${page.firstPage}" aria-label="Previous"> <span aria-hidden="true">«</span> </a> </li> <c:forEach var="s" begin="1" end="${page.pages}"> <li><a href="<%=request.getContextPath()%>/uu/userList?page=${s}">${s}</a></li> </c:forEach> <li> <a href="<%=request.getContextPath()%>/uu/userList?page=${page.lastPage}" aria-label="Next"> <span aria-hidden="true">»</span> </a> </li> </ul> </nav> </center> </html>
九、效果图(没有多少字段也没展示多少字段 )
