摘要電子商務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。本文設計并實現了一套基于 B/S 架構的網上書店系統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、下單結算、訂單處理、庫存維護、評價審核等核心業務。系統后端基于 Spring Boot 3 構建 RESTful 服務持久層采用 MyBatis-Plus 訪問 MySQL 數據庫通過 JWT 實現無狀態身份認證與基于角色的訪問控制前端采用 Vue 3 單頁應用用戶端與商家/管理員后臺采用雙布局設計配合 Element Plus 與 ECharts 實現業務頁面與統計圖表。數據庫共設計 9 張業務表字段命名統一為 snake_case業務層采用外鍵 ID 與 Service 層手動填充關聯信息在下單結算時使用事務校驗庫存并扣減保障數據一致性。經功能測試系統各模塊運行穩定滿足網上書店日常運營的信息化需求對同類電商類 Web 應用開發具有一定的參考價值。技術棧 Spring Boot 3 MyBatis-Plus MySQL Vue 3 Element Plus ECharts數據庫表9張文末獲取聯系文末獲取聯系作者介紹專注計算機課設、畢設輔導個人開發堅持原創非工作室源碼全網唯一。?技術主流SpringBoot Vue 前后端分離MySQLEcharts數據統計可本地運行?配套資料源碼 數據庫 實驗報告/論文 答辯 PPT部署演示遠程調試問題解答技術范圍SpringBoot、Vue、數據可視化、小程序、HLMT、Nodejs、uni-app、MySQL數據庫、ElementUi等設計與開發。適用范圍軟件工程、軟件技術、數據庫課程設計、計算機科學與技術、數據庫系統原理、JavaWeb開發、JavaEE、Java、Web應用開發、動態網頁設計的課程設計、課設、大作業、課程實驗、期末作業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據庫及架構系統數據庫設計為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 !
