一、数据库表的设计

二、后端实现

环境配置

引入mybatis-plus依赖

        <dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.3</version></dependency>

model层

package com.mrjj.java.model;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@NoArgsConstructor
@AllArgsConstructor
@TableName("merchandise_details")
public class MerchandiseDetails {@TableId(type= IdType.AUTO)public int id;public String salesPlatform;public String merchandiseName;public int freightCharge;public String notes;
}

mapper层

package com.mrjj.java.mapper;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.mrjj.java.model.MerchandiseDetails;
import org.apache.ibatis.annotations.Mapper;@Mapper
public interface MerchandiseDetailsMapper extends BaseMapper<MerchandiseDetails> {
}

service层

MerchandiseDetailsService文件

package com.mrjj.java.service;import com.baomidou.mybatisplus.extension.service.IService;
import com.mrjj.java.model.MerchandiseDetails;public interface MerchandiseDetailsService extends IService<MerchandiseDetails> {
}

package com.mrjj.java.service.impl;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.mrjj.java.mapper.MerchandiseDetailsMapper;
import com.mrjj.java.model.MerchandiseDetails;
import com.mrjj.java.service.MerchandiseDetailsService;
import org.springframework.stereotype.Service;@Service("MerchandiseDetailsService")
public class MerchandiseDetailsServiceImpl extends ServiceImpl<MerchandiseDetailsMapper, MerchandiseDetails> implements MerchandiseDetailsService {
}

service层单元测试

package com.mrjj.java.service;import com.mrjj.java.model.MerchandiseDetails;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.transaction.annotation.Transactional;import javax.annotation.Resource;
import java.util.List;@SpringBootTest
@Transactional
public class MerchandiseDetailsServiceTest {@ResourceMerchandiseDetailsService merchandiseDetailsService;@Testpublic void getAll() {List<MerchandiseDetails> list = merchandiseDetailsService.list();System.out.println(list);}@Testpublic void update() {MerchandiseDetails change = new MerchandiseDetails(30, "淘宝", "天堂伞", 16, "质量好");merchandiseDetailsService.updateById(change);}
}

controller层

package com.mrjj.java.controller;import com.mrjj.java.model.MerchandiseDetails;
import com.mrjj.java.model.Result;
import com.mrjj.java.service.MerchandiseDetailsService;
import org.springframework.web.bind.annotation.*;import javax.annotation.Resource;
import java.util.List;@RestController
@RequestMapping("/MerchandiseDetails")
public class MerchandiseDetailsController {@ResourceMerchandiseDetailsService merchandiseDetailsService;@GetMappingpublic Result<List<MerchandiseDetails>> listMerchandiseDetails() {return Result.success(merchandiseDetailsService.list());}@PutMappingpublic Result updateMerchandiseDetails(@RequestBody MerchandiseDetails merchandiseDetails) {boolean result = merchandiseDetailsService.updateById(merchandiseDetails);if (result) {return Result.success("更新商品详细信息成功！");} else {return Result.fail(210, "更新商品详细信息失败", merchandiseDetails);}}
}

三、前端实现

interface接口

export interface MerchandiseDetails {id: number;salesPlatform: string;merchandiseName: string;freightCharge: number;notes: string;
}

接口api层

import request from '../request'
import axios, { type AxiosPromise } from 'axios'
import type { MerchandiseDetails } from '@/types/merchandises_details/types'
const instance = axios.create({baseURL: '/merchandiseDetails',timeout: 30000,headers: { 'Content-Type': 'application/json;charset=utf-8' }})export default instanceexport function listMerchandiseDetailsApi(): AxiosPromise<MerchandiseDetails[]> {return request({url: '/merchandiseDetails',method: 'get',})
}export function updateMerchandiseDetailsApi(data: MerchandiseDetails) {return request({url: '/merchandiseDetails',method: 'put',data: data,})
}
