若依框架使用的是mybatis-plus 分页插件。

参考原文
分页功能 (dromara.org)

1、从controller开始，使用PageQuery接收分页参数

@GetMapping("/companyInfo/listPlantEquipment")
    public TableDataInfo<WbPlantEquipmentDTO> listPlantEquipment(Long companyId, PageQuery pageQuery) {
        return wbCompanyInfoService.queryPlantEquipment(companyId, pageQuery);
    }

2.Service层

TableDataInfo<WbPlantEquipmentDTO> queryPlantEquipment(Long companyId, PageQuery pageQuery);

    @Override
    public TableDataInfo<WbPlantEquipmentDTO> queryPlantEquipment(Long companyId, PageQuery pageQuery) {
         TableDataInfo.build(baseMapper.queryPlantEquipment(companyId, pageQuery.build()));
}

3、mapper

Page<WbPlantEquipmentDTO> queryPlantEquipment( Long companyId, Page<Object> build);

xml

<select id="queryPlantEquipment" resultType="org.dromara.system.domain.dto.WbPlantEquipmentDTO">
        select *
        from wb_company_info  where id=#{companyId}
    </select>
