1、导入相关依赖PageHelper自带了mybatis、mybatis-spring,不排除会报错

<!-- pagehelper分页插件依赖 -->
<dependency>
    <groupId>com.github.pagehelper</groupId>
    <artifactId>pagehelper-spring-boot-starter</artifactId>
    <version>1.2.10</version>
    <exclusions>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2、在application.yml 配置文件中配置指定数据库

#pagehelper配置
pagehelper:
  helper-dialect: mysql

其他相关配置:https://www.cnblogs.com/mengw/p/11673637.html

或者使用配置类

3、使用Pagehelper多条件分页

条件类:

@Data
@AllArgsConstructor
@NoArgsConstructor
public class HouseQueryInfo implements Serializable{
    private static final long serialVersionUID = 1034989291292817460L;
    //private int pageIndex;//当前页码(页面传递)
    //private int pageSize;//页容量(后台设置)
    private String title;
    private String price_on;
    private String price_down;
    private String street_id;
    private String type_id;
    private String floorage_on;
    private String floorage_down;
    
}

service层接口:

public interface IHouseService extends IService<House>{
    //根据条件查询所有房屋信息,分页显示
    List<House> findAllHouse(HouseQueryInfo houseInfo) throws Exception;

    //使用pagehelper分页查询
    public PageInfo<House> findBookPage(Integer pageIndex,Integer pageSize,HouseQueryInfo houseInfo) throws Exception;
}

serviceimpl实现类:

@Service
public class HouseServiceImpl extends ServiceImpl<IHouseMapper, House>  implements IHouseService {
    @Autowired
    private IHouseMapper houseMapper;
    //根据条件查询所有房屋信息,分页显示
    @Override
    public List<House> findAllHouse(HouseQueryInfo houseInfo) throws Exception {
        return houseMapper.findAllHouse(houseInfo);
    }
   //根据所有信息进行分页
    @Override
    public PageInfo<House> findBookPage(Integer pageIndex,Integer pageSize,HouseQueryInfo houseInfo) throws Exception {
        PageHelper.startPage(pageIndex,pageSize);
        PageInfo<House> pageinfo = new PageInfo<>(houseMapper.findAllHouse(houseInfo));
        return pageinfo;
    }

controller层:

PageInfo<House> pageInfo = houseService.findBookPage(houseInfoVo.getPageIndex(),3,houseInfo);
// 将租房信息存入model中
 model.addAttribute("pageInfo", pageInfo);

页面数据的展示:

<TR th:each="house:${pageInfo.getList()}">
      <TD class=house-thumb><span>
    <img th:src="${house.photopath != null} ? |/img/${house.photopath}| :‘../images/thumb_house.gif‘ " width="100" height="75"</span></TD>
      <TD>
          <DL>
               <DT>
                  <A href="#" th:text="${house.title}"></A>
               </DT>
                    <DD>
                       <span th:text="${house.streets.name}"/>
                       <span th:text="${house.streets.district.name}"/>
                       <span th:text="${house.floorage}"/> 平米<BR>联系方式:<span th:text="${house.contact}"/> 
                     </DD>
          </DL>
       </TD>
    <TD class=house-type><span th:text="${house.typess.name}"/></TD>
    <TD class=house-price><SPAN th:text="${house.price}"></SPAN>元/月</TD>
</TR>
