springboot+mybatisplus實現自定義分頁

xml層

<select id="getRecords" parameterType="java.util.HashMap" resultType="com.dongzhengafc.common.entity.approval.ApprovalRecordsEntity">
   select * from table1
   <where>
      <if test="start!=null and start!=''">
         and insert_day &gt;= #{start}
      </if>
      <if test="end!=null and end!=''">
         and insert_day &lt;= #{end}
      </if>

   </where>
</select>

dao層

public interface ApprovalRecordsDao extends BaseMapper<ApprovalRecordsEntity> {
    List<ApprovalRecordsEntity> getRecords(Pagination page, Map<String, Object> map);
}

Service層

public interface ApprovalRecordsService extends IService<ApprovalRecordsEntity>  {

   PageUtils queryPage(Map<String, Object> params);
   
}

Impl層

@Service("approvalRecordsService")
public class ApprovalRecordsServiceImpl extends ServiceImpl<ApprovalRecordsDao, ApprovalRecordsEntity> implements ApprovalRecordsService {

   private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

   @Override
   public PageUtils queryPage(Map<String, Object> params) {
      String start = (String)params.get("start");
      String end = (String)params.get("end");
      //當前頁
      int page = Integer.parseInt((String)params.get("page"));
      //每頁size
      int size = Integer.parseInt((String)params.get("limit"));
      if(StringUtils.isBlank(start)&&StringUtils.isBlank(end)) {
         start = sdf.format(new Date());
         end = sdf.format(new Date());
      }
      params.put("start", start);
      params.put("end", end);
      Page<ApprovalRecordsEntity> result = new Page<ApprovalRecordsEntity>(page, size,"insert_time", false);
      result.setRecords(this.baseMapper.getRecords(result, params));
      return new PageUtils(result);
   }
