摘要電子商務(wù)與移動支付的普及線上購書已成為高校師生及社會公眾獲取圖書的重要方式。傳統(tǒng)線下書店在圖書檢索、庫存查詢、訂單跟蹤等方面存在信息分散、效率較低等問題。本文設(shè)計并實現(xiàn)了一套基于 B/S 架構(gòu)的網(wǎng)上書店系統(tǒng)采用前后端分離模式面向用戶、商家與管理員三類角色覆蓋圖書分類瀏覽、全站圖書查詢、購物車管理、下單結(jié)算、訂單處理、庫存維護、評價審核等核心業(yè)務(wù)。系統(tǒng)后端基于 Spring Boot 3 構(gòu)建 RESTful 服務(wù)持久層采用 MyBatis-Plus 訪問 MySQL 數(shù)據(jù)庫通過 JWT 實現(xiàn)無狀態(tài)身份認證與基于角色的訪問控制前端采用 Vue 3 單頁應(yīng)用用戶端與商家/管理員后臺采用雙布局設(shè)計配合 Element Plus 與 ECharts 實現(xiàn)業(yè)務(wù)頁面與統(tǒng)計圖表。數(shù)據(jù)庫共設(shè)計 9 張業(yè)務(wù)表字段命名統(tǒng)一為 snake_case業(yè)務(wù)層采用外鍵 ID 與 Service 層手動填充關(guān)聯(lián)信息在下單結(jié)算時使用事務(wù)校驗庫存并扣減保障數(shù)據(jù)一致性。經(jīng)功能測試系統(tǒng)各模塊運行穩(wěn)定滿足網(wǎng)上書店日常運營的信息化需求對同類電商類 Web 應(yīng)用開發(fā)具有一定的參考價值。技術(shù)棧 Spring Boot 3 MyBatis-Plus MySQL Vue 3 Element Plus ECharts數(shù)據(jù)庫表9張文末獲取聯(lián)系文末獲取聯(lián)系作者介紹專注計算機課設(shè)、畢設(shè)輔導(dǎo)個人開發(fā)堅持原創(chuàng)非工作室源碼全網(wǎng)唯一。?技術(shù)主流SpringBoot Vue 前后端分離MySQLEcharts數(shù)據(jù)統(tǒng)計可本地運行?配套資料源碼 數(shù)據(jù)庫 實驗報告/論文 答辯 PPT部署演示遠程調(diào)試問題解答技術(shù)范圍SpringBoot、Vue、數(shù)據(jù)可視化、小程序、HLMT、Nodejs、uni-app、MySQL數(shù)據(jù)庫、ElementUi等設(shè)計與開發(fā)。適用范圍軟件工程、軟件技術(shù)、數(shù)據(jù)庫課程設(shè)計、計算機科學與技術(shù)、數(shù)據(jù)庫系統(tǒng)原理、JavaWeb開發(fā)、JavaEE、Java、Web應(yīng)用開發(fā)、動態(tài)網(wǎng)頁設(shè)計的課程設(shè)計、課設(shè)、大作業(yè)、課程實驗、期末作業(yè)實驗報告實驗報告可供大家參考使用功能展示用戶管理員商家數(shù)據(jù)庫及架構(gòu)系統(tǒng)數(shù)據(jù)庫設(shè)計為Controller及Service層核心代碼寫法package com.springboot.controller; import com.springboot.auth.RequireRole; import com.springboot.dto.*; import com.springboot.entity.Book; import com.springboot.entity.UserRole; import com.springboot.service.BookService; import jakarta.validation.Valid; import lombok.RequiredArgsConstructor; import org.springframework.web.bind.annotation.*; RestController RequestMapping(/api/books) RequiredArgsConstructor public class BookController { private final BookService bookService; GetMapping(/browse) RequireRole(UserRole.USER) public ApiResponsePageResultBook browse( RequestParam Long merchant_id, RequestParam(required false) String category, RequestParam(defaultValue 1) int page, RequestParam(defaultValue 10) int size) { return ApiResponse.ok(bookService.listByMerchant(merchant_id, category, page, size)); } GetMapping(/search) RequireRole(UserRole.USER) public ApiResponsePageResultBook search( RequestParam(required false) String keyword, RequestParam(required false) String category, RequestParam(defaultValue 1) int page, RequestParam(defaultValue 10) int size) { return ApiResponse.ok(bookService.searchForUser(keyword, category, page, size)); } GetMapping RequireRole({UserRole.ADMIN, UserRole.MERCHANT}) public ApiResponsePageResultBook list( RequestParam(required false) String keyword, RequestParam(required false) String category, RequestParam(required false) String status, RequestParam(required false) Long merchant_id, RequestParam(defaultValue 1) int page, RequestParam(defaultValue 10) int size) { return ApiResponse.ok(bookService.list(keyword, category, status, merchant_id, page, size)); } GetMapping(/{id}) RequireRole({UserRole.ADMIN, UserRole.MERCHANT, UserRole.USER}) public ApiResponseBook detail(PathVariable Long id) { return ApiResponse.ok(bookService.detail(id)); } PostMapping RequireRole({UserRole.ADMIN, UserRole.MERCHANT}) public ApiResponseBook create(Valid RequestBody BookDTO dto) { return ApiResponse.ok(新增成功, bookService.create(dto)); } PutMapping(/{id}) RequireRole({UserRole.ADMIN, UserRole.MERCHANT}) public ApiResponseBook update(PathVariable Long id, Valid RequestBody BookDTO dto) { return ApiResponse.ok(更新成功, bookService.update(id, dto)); } DeleteMapping(/batch) RequireRole({UserRole.ADMIN, UserRole.MERCHANT}) public ApiResponseVoid batchDelete(Valid RequestBody IdsDTO dto) { bookService.batchDelete(dto.getIds()); return ApiResponse.ok(刪除成功, null); } } package com.springboot.service; import com.baomidou.mybatisplus.core.toolkit.Wrappers; import com.baomidou.mybatisplus.extension.plugins.pagination.Page; import com.springboot.auth.AuthContext; import com.springboot.dto.BookDTO; import com.springboot.dto.PageResult; import com.springboot.entity.Book; import com.springboot.entity.Merchant; import com.springboot.mapper.BookMapper; import com.springboot.mapper.MerchantMapper; import lombok.RequiredArgsConstructor; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import org.springframework.util.StringUtils; import java.util.*; import java.util.stream.Collectors; Service RequiredArgsConstructor public class BookService { private final BookMapper bookMapper; private final MerchantMapper merchantMapper; public PageResultBook list(String keyword, String category, String status, Long merchant_id, int page, int size) { if (AuthContext.isMerchant()) { merchant_id AuthContext.getUserId(); } var wrapper Wrappers.BooklambdaQuery() .eq(merchant_id !
