摘要随着移动互联网与社交媒体的普及网络论坛仍是用户进行深度讨论、知识分享与兴趣交流的重要载体。传统论坛系统往往功能单一、界面陈旧难以满足年轻用户对交互体验与内容治理的双重要求。本文设计并实现了一套基于 B/S 架构的 Web 论坛系统采用前后端分离模式面向普通用户、板块版主与论坛管理员三类角色覆盖板块浏览、发帖回复、点赞收藏、内容举报及后台审核统计等完整业务链路。系统后端基于 Spring Boot 3.2.5 构建 RESTful 服务持久层采用 MyBatis-Plus 3.5.7 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 单页应用配合 Element Plus 组件库与 ECharts 图表库前台采用渐变青蓝年轻化视觉风格后台提供统一管理界面。数据库共设计十张业务表包括管理员、版主、用户、板块、帖子、回复、点赞、收藏与举报等实体字段命名统一采用下划线风格保证接口一致性。系统在业务层采用“外键 ID 关联对象手动填充”的轻量关联策略对点赞与收藏采用唯一索引防止重复操作对举报流程支持版主与管理员分级处理。经功能测试与试运行系统各模块运行稳定权限边界清晰界面交互友好满足中小型社区论坛的日常运营需求对同类 Web 论坛系统的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、期末作业实验报告参考内容实验报告可供大家参考使用功能展示用户管理员博主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.Post; import com.springboot.entity.UserRole; import com.springboot.service.PostService; import jakarta.validation.Valid; import lombok.RequiredArgsConstructor; import org.springframework.web.bind.annotation.*; //帖子管理 RestController RequestMapping(/api/posts) RequiredArgsConstructor public class PostController { private final PostService postService; GetMapping public ApiResponsePageResultPost browse( RequestParam(required false) String keyword, RequestParam(required false) Long section_id, RequestParam(defaultValue 1) int page, RequestParam(defaultValue 10) int size) { return ApiResponse.ok(postService.browse(keyword, section_id, page, size)); } GetMapping(/manage) RequireRole({UserRole.ADMIN, UserRole.MODERATOR}) public ApiResponsePageResultPost listManage( RequestParam(required false) String keyword, RequestParam(required false) String status, RequestParam(required false) Long section_id, RequestParam(defaultValue 1) int page, RequestParam(defaultValue 10) int size) { return ApiResponse.ok(postService.listManage(keyword, status, section_id, page, size)); } GetMapping(/mine) RequireRole({UserRole.USER}) public ApiResponsePageResultPost listMine( RequestParam(defaultValue 1) int page, RequestParam(defaultValue 10) int size) { return ApiResponse.ok(postService.listMine(page, size)); } GetMapping(/{id}) public ApiResponsePost detail(PathVariable Long id) { return ApiResponse.ok(postService.getPublishedAndIncrView(id)); } PostMapping RequireRole({UserRole.USER}) public ApiResponsePost create(Valid RequestBody PostDTO dto) { return ApiResponse.ok(发布成功, postService.create(dto)); } PutMapping(/{id}/flags) RequireRole({UserRole.ADMIN, UserRole.MODERATOR}) public ApiResponsePost updateFlags(PathVariable Long id, RequestBody PostDTO dto) { return ApiResponse.ok(已更新, postService.updateFlags(id, dto)); } PutMapping(/{id}/status) RequireRole({UserRole.ADMIN, UserRole.MODERATOR}) public ApiResponsePost updateStatus(PathVariable Long id, RequestBody StatusDTO dto) { return ApiResponse.ok(状态已更新, postService.updateStatus(id, dto.getStatus())); } DeleteMapping(/batch) RequireRole({UserRole.ADMIN, UserRole.MODERATOR, UserRole.USER}) public ApiResponseVoid batchDelete(RequestBody IdsDTO dto) { postService.batchDelete(dto.getIds()); return ApiResponse.ok(删除成功, null); } DeleteMapping(/{id}) RequireRole({UserRole.ADMIN, UserRole.MODERATOR, UserRole.USER}) public ApiResponseVoid delete(PathVariable Long id) { postService.delete(id); 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.PageResult; import com.springboot.dto.PostDTO; import com.springboot.entity.*; import com.springboot.mapper.*; import lombok.RequiredArgsConstructor; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import org.springframework.util.StringUtils; import java.time.LocalDateTime; import java.util.*; import java.util.stream.Collectors; //帖子管理 Service RequiredArgsConstructor public class PostService { private final PostMapper postMapper; private final SectionMapper sectionMapper; private final UserMapper userMapper; private final ReplyMapper replyMapper; private final LikeMapper likeMapper; private final FavoriteMapper favoriteMapper; private final ModeratorService moderatorService; public PageResultPost browse(String keyword, Long sectionId, int page, int size) { var wrapper Wrappers.PostlambdaQuery() .eq(Post::getStatus, PUBLISHED) .like(StringUtils.hasText(keyword), Post::getTitle, keyword) .eq(sectionId !
