package com.mideaframework.core.web;

import com.google.common.collect.Lists;
import java.io.Serializable;
import java.util.List;

public class PageResponse implements Serializable {
    private static final long serialVersionUID = -2103014265407834780L;
    public List list;
    public Integer totalCount;
    public Integer totalPage;
    public Integer pageNo;
    public Integer pageSize;
    public Integer offset;

    public PageResponse() {
        this.list = Lists.newArrayList();
        this.totalCount = 0;
        this.totalPage = 0;
        this.pageNo = 1;
        this.pageSize = 30;
        this.offset = 0;
    }

    public List getList() {
        return this.list;
    }

    public void setList(List list) {
        this.list = list;
    }

    public Integer getTotalCount() {
        return this.totalCount;
    }

    public void setTotalCount(Integer totalCount) {
        this.totalCount = totalCount;
    }

    public Integer getTotalPage() {
        return this.totalPage;
    }

    public void setTotalPage(Integer totalPage) {
        this.totalPage = totalPage;
    }

    public Integer getPageNo() {
        return this.pageNo;
    }

    public void setPageNo(Integer pageNo) {
        this.pageNo = pageNo;
    }

    public Integer getPageSize() {
        return this.pageSize;
    }

    public void setPageSize(Integer pageSize) {
        this.pageSize = pageSize;
    }

    public Integer getOffset() {
        return this.offset;
    }

    public void setOffset(Integer offset) {
        this.offset = offset;
    }

    public PageResponse(Integer pageNo, Integer pageSize, Integer totalCount, List list) {
        this.list = Lists.newArrayList();
        this.totalCount = 0;
        this.totalPage = 0;
        this.pageNo = 1;
        this.pageSize = 30;
        this.offset = 0;
        this.init(pageNo, pageSize, totalCount, list);
    }

    public PageResponse(Integer pageNo, Integer pageSize, Integer totalCount) {
        this(pageNo, pageSize, totalCount, (List)null);
    }

    public PageResponse(Integer pageNo, Integer pageSize) {
        this(pageNo, pageSize, (Integer)null);
    }

    public void init(Integer pageNo, Integer pageSize, Integer totalCount, List list) {
        if (pageNo != null) {
            this.pageNo = pageNo;
        }

        if (pageSize != null) {
            this.pageSize = pageSize;
        }

        if (this.pageNo > 0) {
            this.offset = this.pageSize * this.pageNo;
        }

        if (totalCount != null) {
            this.totalCount = totalCount;
            this.totalPage = this.totalCount % pageSize > 0 ? this.totalCount / pageSize + 1 : this.totalCount / pageSize;
        }

        if (list != null) {
            this.list = list;
        }

    }
}

步骤2：实体类继承  PagingDomain

public class ErpWorkOrder extends PagingDomain{}

步骤3 数据层 ：

import com.midea.lmes.intelligent.logistics.domain.mes.base.entity.base.ErpWorkOrder;
import com.midea.lmes.intelligent.logistics.dto.mes.base.ErpWorkOrderDto;
import com.mideaframework.core.mapper.BaseMapper;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface ErpWorkOrderMapper extends BaseMapper{}

步骤4：业务层 使用分页

@Override
public PageResponse selectErpWorkOrderPage(ErpWorkOrder erpWorkOrder) {
    PageResponse pagingData = new PageResponse();
    if (null == erpWorkOrder) {
        LOGGER.warn("select erpWorkOrder page, but erpWorkOrder is null...");
        return pagingData;
    }
    //设置工单状态 用于IN 关键字查询
    if(StringUtils.isNotEmpty(erpWorkOrder.getStatusTypeName())){
        String[] str=erpWorkOrder.getStatusTypeName().split(",");
        StringBuffer stringBuffer =new StringBuffer();
        String statusTypeName="";
        List list =new ArrayList();
        for (int i = 0; i  erpWorkOrders = selectErpWorkOrderByIndex(erpWorkOrder);
    if(erpWorkOrders !=null && erpWorkOrders.size()>0){
        SysOrg sysOrg = new SysOrg();;
        for (int i = 0; i  listSysOrg =sysOrgClient.queryLineCodeByCodeAndOrgId(sysOrg);
                if(listSysOrg !=null && listSysOrg.size()>0){
                    for (int j = 0; j  
  
步骤5 控制层
 
  
/**
 * @return 查询集合
 */
 @PostMapping(value = "/fndContainerInvRelations/search")
 public JsonResponse search(@RequestBody FndContainerInvRelation fndContainerInvRelation,HttpServletRequest request) {
     RestDoing doing = jsonResponse -> {
        PageResponse PageResponse = fndContainerInvRelationServiceImpl.selectFndContainerInvRelationPage(fndContainerInvRelation);
        jsonResponse.data = PageResponse;
     };
    return doing.go(request, logger);

 }
