谷粒商城–仓库管理–笔记十 0.解决gulimall-ware模块分页插件未生效问题

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/config/WareMyBatisConfig.java

新增配置文件 (与gulimall-ware模块的MyBatisConfig配置文件其实是一致的)

package site.zhourui.gulimall.ware.config;

import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@EnableTransactionManagement
@MapperScan("site.zhourui.gulimall.ware.dao")
@Configuration
public class WareMyBatisConfig {

    //引入分页插件
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        // 设置请求的页面大于最大页后操作， true调回到首页，false 继续请求  默认false
//        paginationInterceptor.setOverflow(true);
//        // 设置最大单页限制数量，默认 500 条，-1 不受限制
//        paginationInterceptor.setLimit(1000);
        return paginationInterceptor;
    }
}

解决效果

1.启动gulimall-ware

添加配置文件

server:
  port: 11000

spring:
  datasource:
    username: root
    password: root
    url: jdbc:mysql://192.168.157.129:3306/gulimall_wms
    driver-class-name: com.mysql.jdbc.Driver

  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
  application:
    name: gulimall-ware

  jackson:
    date-format: yyyy-MM-dd HH:mm:ss


mybatis-plus:
  mapper-locations: classpath:/mapper/**
        QueryWrapper queryWrapper = new QueryWrapper<>();
        String skuId = (String) params.get("skuId");
        if(!StringUtils.isEmpty(skuId)){
            queryWrapper.eq("sku_id",skuId);
        }

        String wareId = (String) params.get("wareId");
        if(!StringUtils.isEmpty(wareId)){
            queryWrapper.eq("ware_id",wareId);
        }


        IPage page = this.page(
                new Query().getPage(params),
                queryWrapper
        );

        return new PageUtils(page);
    }

重启gulimall-ware服务测试

4.采购需求

原因:商品库存肯定不是手动创建添加的,而是系统增加的

需要增加库存就需要创建采购需求,合并成为采购单,完成采购单商品库存才能增加

0.采购流程

1.采购需求查询

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/PurchaseDetailServiceImpl.java

修改queryPage方法实现

@Override
    public PageUtils queryPage(Map params) {

        

        QueryWrapper queryWrapper = new QueryWrapper();

        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            //purchase_id  sku_id
            queryWrapper.and(w->{
                w.eq("purchase_id",key).or().eq("sku_id",key);
            });
        }

        String status = (String) params.get("status");
        if(!StringUtils.isEmpty(status)){
            //purchase_id  sku_id
            queryWrapper.eq("status",status);
        }

        String wareId = (String) params.get("wareId");
        if(!StringUtils.isEmpty(wareId)){
            //purchase_id  sku_id
            queryWrapper.eq("ware_id",wareId);
        }

        IPage page = this.page(
                new Query().getPage(params),
                queryWrapper
        );

        return new PageUtils(page);
    }

实现效果

2.合并采购需求

采购需求需要合并成为采购单,然后再被分配

合并整单操作就是讲采购需求合并为采购单

1.未指定采购单查询

合并采购需求时需要可以指定到采购单,需要查询为被领取的采购单采购单

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/PurchaseService.java

新增接口

PageUtils queryPageUnreceivePurchase(Map params);

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/PurchaseServiceImpl.java

新增接口实现

 @Override
    public PageUtils queryPageUnreceivePurchase(Map params) {
        IPage page = this.page(
                new Query().getPage(params),
                new QueryWrapper().eq("status",0).or().eq("status",1)
        );

        return new PageUtils(page);
    }

2.合并采购单 1.新增MergeVo对象

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/vo/MergeVo.java

package site.zhourui.gulimall.ware.vo;

import lombok.Data;

import java.util.List;

@Data
public class MergeVo {

   private Long purchaseId; //整单id
   private List items;//[1,2,3,4] //合并项集合
}

2.新增采购相关常量

gulimall-common/src/main/java/site/zhourui/common/constant/WareConstant.java

package site.zhourui.common.constant;

public class WareConstant {

    public enum  PurchaseStatusEnum{
        CREATED(0,"新建"),ASSIGNED(1,"已分配"),
        RECEIVE(2,"已领取"),FINISH(3,"已完成"),
        HASERROR(4,"有异常");
        private int code;
        private String msg;

        PurchaseStatusEnum(int code,String msg){
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }


    public enum  PurchaseDetailStatusEnum{
        CREATED(0,"新建"),ASSIGNED(1,"已分配"),
        BUYING(2,"正在采购"),FINISH(3,"已完成"),
        HASERROR(4,"采购失败");
        private int code;
        private String msg;

        PurchaseDetailStatusEnum(int code,String msg){
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }
}

3.新增合并接口

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/PurchaseService.java

新增接口

void mergePurchase(MergeVo mergeVo);

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/PurchaseServiceImpl.java

新增接口实现

 @Transactional
    @Override
    public void mergePurchase(MergeVo mergeVo) {
        Long purchaseId = mergeVo.getPurchaseId();
        if(purchaseId == null){
            //1、新建一个
            PurchaseEntity purchaseEntity = new PurchaseEntity();

            purchaseEntity.setStatus(WareConstant.PurchaseStatusEnum.CREATED.getCode());
            purchaseEntity.setCreateTime(new Date());
            purchaseEntity.setUpdateTime(new Date());
            this.save(purchaseEntity);
            purchaseId = purchaseEntity.getId();
        }

        //TODO 确认采购单状态是0,1才可以合并

        List items = mergeVo.getItems();
        Long finalPurchaseId = purchaseId;
        List collect = items.stream().map(i -> {
            PurchaseDetailEntity detailEntity = new PurchaseDetailEntity();

            detailEntity.setId(i);
            detailEntity.setPurchaseId(finalPurchaseId);
            detailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.ASSIGNED.getCode());
            return detailEntity;
        }).collect(Collectors.toList());


        detailService.updateBatchById(collect);

        PurchaseEntity purchaseEntity = new PurchaseEntity();
        purchaseEntity.setId(purchaseId);
        purchaseEntity.setUpdateTime(new Date());
        this.updateById(purchaseEntity);
    }

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/controller/PurchaseController.java

@PostMapping("/merge")
    public R merge(@RequestBody MergeVo mergeVo){

        purchaseService.mergePurchase(mergeVo);
        return R.ok();
    }

5.采购单 1.采购单查询(此部分视频没有)

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/PurchaseServiceImpl.java

修改queryPage方法

@Override
    public PageUtils queryPage(Map params) {
        QueryWrapper queryWrapper = new QueryWrapper();

        String key = (String) params.get("key");
        if(!StringUtils.isEmpty(key)){
            //purchase_id  sku_id
            queryWrapper.and(w->{
                w.like("assignee_name",key);
            });
        }

        String status = (String) params.get("status");
        if(!StringUtils.isEmpty(status)){
            //purchase_id  sku_id
            queryWrapper.eq("status",status);
        }
        IPage page = this.page(
                new Query().getPage(params),
                queryWrapper
        );

        return new PageUtils(page);
    }

2.采购单查询前端部分

src/views/modules/ware/purchase.vue

此处添加状态值
status: this.dataForm.status,

3.领取采购单 1.新增PurchaseItemDoneVo对象

package site.zhourui.gulimall.ware.vo;

import lombok.Data;

@Data
public class PurchaseItemDoneVo {
    //{itemId:1,status:4,reason:""}
    private Long itemId;
    private Integer status;
    private String reason;
}

2.新增PurchaseDoneVo对象

package site.zhourui.gulimall.ware.vo;

import lombok.Data;

import javax.validation.constraints.NotNull;
import java.util.List;

@Data
public class PurchaseDoneVo {

    @NotNull
    private Long id;//采购单id

    private List items;
}

3.领取采购单接口

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/PurchaseService.java

新增接口

    void received(List ids);

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/PurchaseServiceImpl.java

新增接口实现

@Override
public void received(List ids) {
    //1、确认当前采购单是新建或者已分配状态
    List collect = ids.stream().map(id -> {
        PurchaseEntity byId = this.getById(id);
        return byId;
    }).filter(item -> {
        if (item.getStatus() == WareConstant.PurchaseStatusEnum.CREATED.getCode() ||
                item.getStatus() == WareConstant.PurchaseStatusEnum.ASSIGNED.getCode()) {
            return true;
        }
        return false;
    }).map(item->{
        item.setStatus(WareConstant.PurchaseStatusEnum.RECEIVE.getCode());
        item.setUpdateTime(new Date());
        return item;
    }).collect(Collectors.toList());

    //2、改变采购单的状态
    this.updateBatchById(collect);



    //3、改变采购项的状态
    collect.forEach((item)->{
        List entities = detailService.listDetailByPurchaseId(item.getId());
        List detailEntities = entities.stream().map(entity -> {
            PurchaseDetailEntity entity1 = new PurchaseDetailEntity();
            entity1.setId(entity.getId());
            entity1.setStatus(WareConstant.PurchaseDetailStatusEnum.BUYING.getCode());
            return entity1;
        }).collect(Collectors.toList());
        detailService.updateBatchById(detailEntities);
    });
}

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/controller/PurchaseController.java

    @PostMapping("/received")
    public R received(@RequestBody List ids){

        purchaseService.received(ids);

        return R.ok();
    }

4.测试

http://localhost:88/api/ware/purchase/received

测试结果

4.完成采购 1.远程调用商品服务增加商品库存

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/feign/ProductFeignService.java

package site.zhourui.gulimall.ware.feign;


import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import site.zhourui.common.utils.R;

@FeignClient("gulimall-product")
public interface ProductFeignService {

    
    @RequestMapping("/product/skuinfo/info/{skuId}")
    public R info(@PathVariable("skuId") Long skuId);
}

2.增加库存接口

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/WareSkuService.java

    void addStock(Long skuId, Long wareId, Integer skuNum);

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/WareSkuServiceImpl.java

@Override
    public void addStock(Long skuId, Long wareId, Integer skuNum) {
        //1、判断如果还没有这个库存记录新增
        List entities = wareSkuDao.selectList(new QueryWrapper().eq("sku_id", skuId).eq("ware_id", wareId));
        if(entities == null || entities.size() == 0){
            WareSkuEntity skuEntity = new WareSkuEntity();
            skuEntity.setSkuId(skuId);
            skuEntity.setStock(skuNum);
            skuEntity.setWareId(wareId);
            skuEntity.setStockLocked(0);
            //TODO 远程查询sku的名字，如果失败，整个事务无需回滚
            //1、自己catch异常
            //TODO 还可以用什么办法让异常出现以后不回滚？高级
            try {
                R info = productFeignService.info(skuId);
                Map data = (Map) info.get("skuInfo");

                if(info.getCode() == 0){
                    skuEntity.setSkuName((String) data.get("skuName"));
                }
            }catch (Exception e){

            }


            wareSkuDao.insert(skuEntity);
        }else{
            wareSkuDao.addStock(skuId,wareId,skuNum);
        }

    }

3.完成采购接口

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/PurchaseService.java

void done(PurchaseDoneVo doneVo);

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/service/impl/PurchaseServiceImpl.java

@Transactional
    @Override
    public void done(PurchaseDoneVo doneVo) {

        Long id = doneVo.getId();


        //2、改变采购项的状态
        Boolean flag = true;
        List items = doneVo.getItems();

        List updates = new ArrayList<>();
        for (PurchaseItemDoneVo item : items) {
            PurchaseDetailEntity detailEntity = new PurchaseDetailEntity();
            if(item.getStatus() == WareConstant.PurchaseDetailStatusEnum.HASERROR.getCode()){
                flag = false;
                detailEntity.setStatus(item.getStatus());
            }else{
                detailEntity.setStatus(WareConstant.PurchaseDetailStatusEnum.FINISH.getCode());
                3、将成功采购的进行入库
                PurchaseDetailEntity entity = detailService.getById(item.getItemId());
                wareSkuService.addStock(entity.getSkuId(),entity.getWareId(),entity.getSkuNum());

            }
            detailEntity.setId(item.getItemId());
            updates.add(detailEntity);
        }

        detailService.updateBatchById(updates);

        //1、改变采购单状态
        PurchaseEntity purchaseEntity = new PurchaseEntity();
        purchaseEntity.setId(id);
        purchaseEntity.setStatus(flag?WareConstant.PurchaseStatusEnum.FINISH.getCode():WareConstant.PurchaseStatusEnum.HASERROR.getCode());
        purchaseEntity.setUpdateTime(new Date());
        this.updateById(purchaseEntity);
    }

gulimall-ware/src/main/java/site/zhourui/gulimall/ware/controller/PurchaseController.java

///ware/purchase/done
    @PostMapping("/done")
    public R finish(@RequestBody PurchaseDoneVo doneVo){

        purchaseService.done(doneVo);

        return R.ok();
    }

4.测试

http://localhost:88/api/ware/purchase/done
{
   "id": 1,
   "items": [{"itemId":1,"status":3,"reason":""}]
}

测试结果

6.SPU规格维护 1.点击规格404问题

解决方案

src/router/index.js 下添加以下代码

{ path: '/product-attrupdate', component: _import('modules/product/attrupdate'), name: 'attr-update', meta: { title: '规格维护', isTab: true } }

解决效果

2.根据spuid查询属性值查询接口

gulimall-product/src/main/java/site/zhourui/gulimall/product/controller/AttrController.java

新增接口

List baseAttrlistforspu(Long spuId);

gulimall-product/src/main/java/site/zhourui/gulimall/product/service/impl/ProductAttrValueServiceImpl.java

新增接口实现类

@Override
    public List baseAttrlistforspu(Long spuId) {
        List entities = this.baseMapper.selectList(new QueryWrapper().eq("spu_id", spuId));
        return entities;
    }

gulimall-product/src/main/java/site/zhourui/gulimall/product/controller/AttrController.java

// /product/attr/base/listforspu/{spuId}
    @GetMapping("/base/listforspu/{spuId}")
    public R baseAttrlistforspu(@PathVariable("spuId") Long spuId){

        List entities = productAttrValueService.baseAttrlistforspu(spuId);

        return R.ok().put("data",entities);
    }

效果

3.修改spuid对应的属性值接口

gulimall-product/src/main/java/site/zhourui/gulimall/product/controller/AttrController.java

新增接口

void updateSpuAttr(Long spuId, List entities);

gulimall-product/src/main/java/site/zhourui/gulimall/product/service/impl/ProductAttrValueServiceImpl.java

新增接口实现类

@Transactional
    @Override
    public void updateSpuAttr(Long spuId, List entities) {
        //1、删除这个spuId之前对应的所有属性
        this.baseMapper.delete(new QueryWrapper().eq("spu_id",spuId));


        List collect = entities.stream().map(item -> {
            item.setSpuId(spuId);
            return item;
        }).collect(Collectors.toList());
        this.saveBatch(collect);
    }

gulimall-product/src/main/java/site/zhourui/gulimall/product/controller/AttrController.java

///product/attr/update/{spuId}
    @PostMapping("/update/{spuId}")
    public R updateSpuAttr(@PathVariable("spuId") Long spuId,
                           @RequestBody List entities){

        productAttrValueService.updateSpuAttr(spuId,entities);

        return R.ok();
    }

效果

机身长度属性修改成功
