1.pom文件

        <!--pagehelper -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>
            <artifactId>pagehelper-spring-boot-starter</artifactId>
            <version>1.2.5</version>
        </dependency>

2.application.xml

本项目数据库为oracle

# PageHelper分页插件
pagehelper:
  helperDialect: oracle
  reasonable: true
  supportMethodsArguments: true
  params: count=countSql

3.使用

    public Result<*>(*VO *VO) {
        Result<*> resultVO = new Result<>();
        // 分页
        Page page = new Page();
        if (!CommonUtil.isEmpty(*VO.getPageNum()) && !CommonUtil.isEmpty(*VO.getPageSize())) {
            page = PageHelper.startPage(*VO.getPageNum(), *VO.getPageSize());
            resultVO.setPageNum(*VO.getPageNum());
            resultVO.setPageSize(*VO.getPageSize());
        }
        // ASC是根据id 正向排序，DESC是反向排序
        if (!CommonUtil.isEmpty(*VO.getOrder())) {
            PageHelper.orderBy(*VO.getOrder());
        }
        // 业务查询 只有这一句是业务查询！！！
        List<*VO> result = *Service.query(*VO);
        // 分页总数封装
        Long total = page.getTotal();
        resultVO.setTotal(total);
        // 实体封装
        resultVO.setData(result );
        return resultVO;
    }

注意：Result实体类和输入实体都需要继承BaseEntity

public class *VO extends BaseEntity

public class BaseEntity {

    /**
     * 页码
     */
    private Integer pageNum;

    /**
     * 条数
     */
    private Integer pageSize;

    /**
     * 返回总数
     */
    private Long total;

    /**
     * 排序字段
     */
    private String order;

    /**
     * 数据权限
     */
    private String dataScope;
}
