二、技术选型
后端架构：
Spring Boot 3.1.6 | MyBatis-Plus 3.5.3.2 | Spring Security 6.1.5
Redis 7.0 | Elasticsearch 8.9.0 | MinIO 8.5.7前端架构：
Vue3 + TypeScript | Element Plus 2.3.14 | ECharts 5.4.2

校园活动摄影平台核心模块实现详解
一、活动管理子系统实现
1. 可视化活动日历实现
java:src/main/java/com/campus/activity/controller/ActivityController.java">// 活动日历数据接口
@GetMapping("/calendar")
@PreAuthorize("hasAnyRole('ORGANIZER','PHOTOGRAPHER')")
public R<List<ActivityCalendarVO>> getCalendarData(@RequestParam @DateTimeFormat(pattern="yyyy-MM") String month) {return R.success(activityService.getCalendarData(month));
}
<script setup>
import FullCalendar from '@fullcalendar/vue3';
const fetchEvents = async (info) => {const { data } = await api.get(`/activity/calendar?month=${info.startStr}`);return data.map(item => ({title: item.activityName,start: item.startTime,end: item.endTime,color: item.status === 1 ? '#67C23A' : '#909399'}));
};
</script>
2. 多维度权限控制实现
java:src/main/java/com/campus/common/config/SecurityConfig.java">@Bean
SecurityFilterChain filterChain(HttpSecurity http) throws Exception {http.authorizeHttpRequests(auth -> auth.requestMatchers("/activity/**").hasAnyRole("ORGANIZER", "ADMIN").requestMatchers("/works/**").hasAnyRole("PHOTOGRAPHER", "JUDGE").anyRequest().authenticated());return http.build();
}
3. 实时数据看板实现
java:src/main/java/com/campus/activity/service/impl/DashboardServiceImpl.java">public Map<String, Object> getRealTimeStats() {Map<String, Object> stats = new LinkedHashMap<>();// 使用Redis原子操作获取实时数据stats.put("todayVisitors", redisTemplate.opsForValue().increment("stats:visitors:"+LocalDate.now()));stats.put("activityCount", redisTemplate.opsForZSet().size("hot_activities"));return stats;
}
二、作品展示模块实现
1. 作品上传与元数据存储
java:src/main/java/com/campus/works/controller/WorkController.java">@PostMapping("/upload")
public R<String> uploadWork(@RequestPart MultipartFile file, @Valid @RequestPart WorkUploadDTO dto) {// 校验文件类型if (!FileTypeUtil.getType(file.getInputStream()).equals("jpg")) {throw new BusinessException("仅支持JPG格式");}String objectName = minioService.uploadWithWatermark(file);return R.success(workService.saveWork(dto, objectName));
}
2. 作品分页查询实现
java:src/main/java/com/campus/works/service/impl/WorkServiceImpl.java">public Page<WorkVO> listWorks(WorkQueryDTO query) {return workMapper.selectPage(new Page<>(query.getPage(), query.getSize()), Wrappers.<Work>lambdaQuery().eq(query.getActivityId() != null, Work::getActivityId, query.getActivityId()).eq(query.getStatus() != null, Work::getStatus, query.getStatus()).orderByDesc(Work::getVotes)).convert(this::toVO);
}
3. 前端作品展示组件
<template><div class="masonry-grid"><div v-for="work in works" :key="work.id" class="grid-item"><el-image :src="work.thumbnailUrl" :preview-src-list="[work.originalUrl]"loading="lazy":initial-index="0"><template #error><div class="image-error">加载失败</div></template></el-image><div class="work-meta"><span>{{ work.authorName }}</span><vote-button :work-id="work.id"/></div></div></div>
</template>
关键实现点说明
-
混合存储策略：
- 原始图片存储到MinIO（保留EXIF信息）
- 生成三种规格缩略图（1024px/512px/256px）
- 使用CDN加速缩略图访问
-
缓存优化方案：
java:src/main/java/com/campus/works/service/impl/WorkServiceImpl.java">@Cacheable(value = "works", key = "#id", unless = "#result == null")
public WorkDetailVO getWorkDetail(Long id) {return workMapper.selectDetailById(id);
}@CacheEvict(value = "works", key = "#workId")
public void updateVoteCount(Long workId) {// 更新投票数逻辑
}
-
安全控制措施：
- EXIF信息清洗（去除GPS定位数据）
- 动态水印生成（包含用户ID和时间戳）
- 防盗链签名（有效期30分钟）
-
前端性能优化：
<script setup>
const observer = useIntersectionObserver(entries => entries.forEach(entry => {if (entry.isIntersecting) {loadWork(entry.target.dataset.id);}})
);onMounted(() => {document.querySelectorAll('.grid-item').forEach(el => {observer.observe(el);});
});
</script>
校园活动摄影平台互动社区与数据统计实现
三、互动社区功能实现
1. 热度加权推荐算法
java:src/main/java/com/campus/recommend/service/impl/RecommendServiceImpl.java">public List<WorkVO> getHotWorks(int size) {FunctionScoreQueryBuilder functionQuery = QueryBuilders.functionScoreQuery().add(QueryBuilders.rangeQuery("createTime").gte("now-7d/d"),ScoreFunctionBuilders.weightFactorFunction(0.3f)).add(QueryBuilders.termQuery("isFeatured", true),ScoreFunctionBuilders.weightFactorFunction(1.5f)).scoreMode("sum");return elasticsearchTemplate.search(NativeQuery.builder().withQuery(functionQuery).withPageable(PageRequest.of(0, size)).build(), WorkDocument.class).stream().map(this::convertToVO).collect(Collectors.toList());
}
2. 三级评论系统实现
java:src/main/java/com/campus/comment/controller/CommentController.java">@GetMapping("/tree/{targetId}")
public R<List<CommentNodeVO>> getCommentTree(@PathVariable String targetId,@RequestParam(defaultValue = "0") int level) {return R.success(commentService.getCommentTree(targetId, level));
}// 使用闭包表存储评论层级关系
@Entity
@Table(name = "comment_closure")
public class CommentClosure {@Id@GeneratedValue(strategy = GenerationType.IDENTITY)private Long id;private Long ancestor;private Long descendant;private Integer depth;
}
3. 实时弹幕支持
java:src/main/java/com/campus/websocket/handler/BarrageWebSocketHandler">@Component
public class BarrageWebSocketHandler extends TextWebSocketHandler {@Overrideprotected void handleTextMessage(WebSocketSession session, TextMessage message) {BarrageDTO dto = JSON.parseObject(message.getPayload(), BarrageDTO.class);// 敏感词过滤if (sensitiveFilter.contains(dto.getContent())) {session.sendMessage(new TextMessage("ERROR:包含敏感词"));return;}// 广播给同活动用户redisTemplate.convertAndSend("channel:barrage:"+dto.getActivityId(), JSON.toJSONString(dto));}
}
4. 版权水印服务
java:src/main/java/com/campus/common/service/impl/WatermarkServiceImpl.java">public void addTextWatermark(InputStream input, OutputStream output, String text) {BufferedImage image = ImageIO.read(input);Graphics2D g = image.createGraphics();// 设置水印参数g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.4f));g.setFont(new Font("微软雅黑", Font.BOLD, 30));g.setColor(Color.WHITE);// 计算水印位置FontMetrics metrics = g.getFontMetrics();int x = image.getWidth() - metrics.stringWidth(text) - 10;int y = image.getHeight() - metrics.getHeight() + 30;// 绘制文字和边框g.drawString(text, x, y);g.drawRect(x-5, y-metrics.getAscent()-5, metrics.stringWidth(text)+10, metrics.getHeight()+5);g.dispose();ImageIO.write(image, "jpg", output);
}
四、数据统计中心实现
1. 实时数据采集
java:src/main/java/com/campus/statistics/job/RealTimeDataJob.java">@Scheduled(fixedRate = 60000)
public void aggregateData() {// 从Redis获取原始数据Map<String, String> rawData = redisTemplate.opsForHash().entries("stats:real_time");// 生成统计快照StatsSnapshot snapshot = new StatsSnapshot();snapshot.setUv(rawData.values().stream().distinct().count());snapshot.setPv(rawData.values().size());// 存入ElasticsearchelasticsearchTemplate.save(snapshot);
}
2. 可视化分析接口
<script setup>
const loadData = async () => {const requests = [api.get('/stats/activity?type=heatmap'),api.get('/stats/user?type=geo'),api.get('/stats/works?type=category')];const [heatmap, geo, category] = await Promise.all(requests);heatmapChart.setOption({calendar: { top: 30 },visualMap: { min: 0, max: 1000 },series: { data: heatmap.data }});geoChart.setOption({tooltip: { trigger: 'item' },visualMap: { type: 'piecewise' },series: { data: geo.data }});
};
</script>
3. 数据大屏组件
java:src/main/java/com/campus/statistics/controller/StatsController.java">@GetMapping("/complex")
public R<ComplexStatsVO> getComplexStats(@RequestParam String dimension) {ComplexStatsVO vo = new ComplexStatsVO();// 并行获取各维度数据CompletableFuture<ActivityStats> activityFuture = statsService.getActivityStats();CompletableFuture<UserStats> userFuture = statsService.getUserStats();CompletableFuture<WorkStats> workFuture = statsService.getWorkStats();CompletableFuture.allOf(activityFuture, userFuture, workFuture).join();vo.setActivityStats(activityFuture.join());vo.setUserStats(userFuture.join());vo.setWorkStats(workFuture.join());return R.success(vo);
}
关键技术实现说明
-
混合推荐策略：
- 时间衰减因子：每天衰减15%热度值
- 互动权重：浏览1分，点赞3分，收藏5分，评论2分
- 人工加权：运营人员可手动提升优质内容
-
弹幕优化方案：
消息处理流程：
客户端 -> WebSocket网关 -> Kafka消息队列 -> 分布式处理节点 -> Redis发布订阅 -> 客户端频率控制规则：
- 同一用户：5秒内不超过3条
- 全局频率：每秒不超过1000条
- 敏感词过滤：采用DFA算法实现毫秒级检测
- 统计架构设计：
java:src/main/java/com/campus/statistics/config/StatsConfig.java">@Bean
public StatsPipeline statsPipeline() {return StatsPipeline.builder().addSource(new RedisSource(redisTemplate)) // 实时数据.addSource(new ESSource(elasticsearchTemplate)) // 历史数据.addProcessor(new UVProcessor()) // 独立访客计算.addProcessor(new RetentionProcessor()) // 留存率计算.addSink(new MysqlSink()) // 结构化存储.addSink(new ESRealTimeSink()) // 实时分析.build();
}
- 水印安全方案：
水印信息编码规则：
{用户ID}-{时间戳}-{设备指纹}-{CRC校验码}实现特性：
- 隐形水印：使用LSB算法在图片元数据中嵌入加密信息
- 动态位置：根据图片内容自动选择干扰最小的区域
- 抗编辑性：支持经过裁剪、缩放后仍可识别
