SSM框架使用分页插件 PageHelper进行分页

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%>">

<nav aria-label="Page navigation">

   </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>
