无需其他关联配置

启动：



mybatis分页：

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
    @Override
    public PageInfo<DictBuildingWithBLOBs> getBuildingByPage(BuildingQueryDto queryDto) {
        PageHelper.startPage(queryDto.getPageNo(),queryDto.getPageSize());
        return new PageInfo(dictBuildingMapper.queryBuilding());
    }
