引入Jar依赖

Springboot的依赖此次省略，pom.xml

		<!-- springboot分页插件 -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.3.0</version>
        </dependency>

yml配置

# 分页配置
pagehelper:
  helper-dialect: mysql
  reasonable: true
  support-methods-arguments: true
  params: count=countSql

Service业务层代码

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;

@Override
    public PageInfo queryUserPage(User user, Page page) {
        PageHelper.startPage(page.getPageNum(), page.getPageSize());
        List<User> userList = userDao.queryList(user);
        return new PageInfo<>(userList);
    }

返回数据：
