首先引入jar包：

     <dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId>       </dependency>

然后在mybatis配置文件中配置：

SqlMapConfig.xml

?

?

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration><plugins><!-- com.github.pagehelper 為 PageHelper 類所在包名 --><plugin interceptor="com.github.pagehelper.PageHelper"><!-- 設置數據庫類型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL 六種數據庫--><property name="dialect" value="mysql"/></plugin></plugins>
</configuration>

?

代碼中使用：

Service

package com.pinyougou.sellergoods.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import com.alibaba.dubbo.config.annotation.Service;
import com.github.pagehelper.Page;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.pinyougou.mapper.TbBrandMapper;
import com.pinyougou.pojo.TbBrand;
import com.pinyougou.sellergoods.service.BrandService;import entity.PageResult;@Service
public class BrandServiceImpl implements BrandService {@Autowiredprivate TbBrandMapper brandMapper;
@Overridepublic PageResult findPage(int pageNum, int pageSize) {//聲明下面的查詢要使用分頁插件
        PageHelper.startPage(pageNum, pageSize);//查詢方法一：直接將查詢結果強轉成 page對象Page<TbBrand> page = (Page<TbBrand>) brandMapper.selectByExample(null);return new PageResult(page.getTotal(), page.getResult()); //查詢方法二：將查詢結果封裝成pageInfo對象
//        List<TbBrand> list = brandMapper.selectByExample(null);
//        PageInfo<TbBrand> pageInfo = new PageInfo<>(list);
//        return new PageResult(pageInfo.getTotal(), pageInfo.getList()); 
    }}

Controller:

package com.pinyougou.manager.controller;import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
