摘要电子商务与移动支付的普及线上购书已成为高校师生及社会公众获取图书的重要方式。传统线下书店在图书检索、库存查询、订单跟踪等方面存在信息分散、效率较低等问题。本文设计并实现了一套基于 B/S 架构的网上书店系统采用前后端分离模式面向用户、商家与管理员三类角色覆盖图书分类浏览、全站图书查询、购物车管理、下单结算、订单处理、库存维护、评价审核等核心业务。系统后端基于 Spring Boot 3 构建 RESTful 服务持久层采用 MyBatis-Plus 访问 MySQL 数据库通过 JWT 实现无状态身份认证与基于角色的访问控制前端采用 Vue 3 单页应用用户端与商家/管理员后台采用双布局设计配合 Element Plus 与 ECharts 实现业务页面与统计图表。数据库共设计 9 张业务表字段命名统一为 snake_case业务层采用外键 ID 与 Service 层手动填充关联信息在下单结算时使用事务校验库存并扣减保障数据一致性。经功能测试系统各模块运行稳定满足网上书店日常运营的信息化需求对同类电商类 Web 应用开发具有一定的参考价值。技术栈 Spring Boot 3 MyBatis-Plus MySQL Vue 3 Element Plus ECharts数据库表9张文末获取联系文末获取联系作者介绍专注计算机课设、毕设辅导个人开发坚持原创非工作室源码全网唯一。✅技术主流SpringBoot Vue 前后端分离MySQLEcharts数据统计可本地运行✅配套资料源码 数据库 实验报告/论文 答辩 PPT部署演示远程调试问题解答技术范围SpringBoot、Vue、数据可视化、小程序、HLMT、Nodejs、uni-app、MySQL数据库、ElementUi等设计与开发。适用范围软件工程、软件技术、数据库课程设计、计算机科学与技术、数据库系统原理、JavaWeb开发、JavaEE、Java、Web应用开发、动态网页设计的课程设计、课设、大作业、课程实验、期末作业实验报告实验报告可供大家参考使用功能展示用户管理员商家数据库及架构系统数据库设计为Controller及Service层核心代码写法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(删除成功, 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 !
