fallbackExecution=true**：5 个 `@TransactionalEventListener` 原 `fallbackExecution=true` 隐性削弱"AFTER_COMMIT 才发 MQ"不变量——未来若新增非事务发布点（容易疏漏）会致消费者读到脏数据。恢复默认 `false`（无事务时 Spring 输出 WARN 并丢弃事件，强制要求所有发布点必须在

MeterRegistryPostProcessor 在 BeanPostProcessor 阶段强制枚举 MeterBinder 候选 → MetricsConfig 早于 RedisConfig 实例化致 NoSuchBean。@Lazy 让 Spring 注入代理对象，调度器首次执行时才解析真实 Bean ✅ +- **MyBatis Enum Handler 改 `EnumTypeHandler`**：MybatisEnumTypeHandler 强制要求 @EnumValue 注解，与项目所有业务枚举（按 name 与 DB ENUM 互转）的设计意图不符，启动报 `Could not find @EnumValue in Class`。改用 MyBatis 标准 EnumTypeHandler ✅ +- **Flyway

2026-06-19） + +> 针对真机走查发现的 9 项前端+后端问题，进行 3 轮回归修复。全量 16 个文件修改，涉及搜索页/谈判流式/取消预约/返回导航。 + +**搜索页修复（8 项）**： +- ✅ **titlebar 缺失** — `fragment_search.xml` 顶部引入 `page_toolbar`；`SearchFragment` 改继承 `BaseFragment` 并调 `setupToolbar` +- ✅ **分类导航箭头** — `strings.xml` 中 `category_nav = "分类导航 ▸"` 删除 Unicode `▸`（此前反复误改 `item_category.xml` 的 `ivExpand` ImageView） +- ✅ **清空按钮 icon** — 新建 `drawable/ic_close_vector.xml`（标准 X 形），替换 `ic_search_vector` + `rotation="45"` hack +- ✅ **热门搜索词** — 硬编码词条从 8 个扩展到 23 个 +- ✅ **搜索结果展示词条** — `SearchViewModel` 新增 `searchMethodLabel`（关键词搜索/ISBN搜索/分类浏览/高级搜索），格式 `关键词搜索 "机器学习" 找到 5 条结果` +- ✅ **"继续搜索"按钮** — 从 `fragment_search_results.xml` 删除（与 `page_toolbar` 返回按钮冲突） +- ✅ **ISBN 扫码返回无效** — `removeExtra("isbn")` 防止 `navigateUp` 返回 SearchFragment 时 `onViewCreated` 重复触发导航死循环 +- ✅ **返回按钮失效** — `BaseFragment.setupToolbar` 中 `navigateUp()` 在 startDestination 返回 false 时兜底调 `onBackPressed()` + +**谈判流式防闪退（4 项）**： +- ✅ **SSE `done` 事件丢失** — 后端 `event:done` 后 `data:` 为空导致 `dataBuf.length()==0`，`dispatchEvent` 被跳过。修复：空行时优先检查 `"done".equals(event)` +- ✅ **流结束后误报错** — `parseSseStream` 改为返回 `boolean`（done→true），`fromCallable` 捕获 `body.close()` 的 IOException 后按 `completed` 抑制（服务端 `emitter.complete()` 关闭连接导致 `close()` 抛异常） +- ✅ **流式跨 VM 污染** — `AcquisitionViewModel.onCleared()` 移除 `repository.disposeStreams()` 调用（repository 是 Hilt 全局单例，创建页 VM 清理会错误取消详情页的活跃流） +- ✅ **流式生命周期** — `NegotiationDetailFragment.onDestroyView` 主动调 `viewModel.disposeStreams()`；`AcquisitionRepository` 新增 `volatile streamCancelled` + `parseSseStream` 循环内检查 + +**取消预约修复（4 项）**： +- ✅ **后端终态扩展** — `ReservationServiceImpl.cancel()` 从仅允许 `WAITING` 改为拒绝 RESERVED/COMPLETED/EXPIRED/CANCELLED 四种终态，允许 NOTIFIED 取消 +- ✅ **V6 唯一约束根治** — 新增 `ReservationMapper.physicalCleanStaleWaiting`（`@Delete` 物理 DELETE，绕过 MyBatis-Plus 逻辑删除）。`reserve()` 前置调用清理 `deleted=1` 的旧 WAITING 记录释放索引槽位；`cancel()` 遇 `DataIntegrityViolationException` 时 `deleteById`→`physicalClean` +- ✅ **前端错误可见** — `ReservationListFragment` 改继承 `BaseFragment` 并调 `observeError()`；`ReservationViewModel.cancelReservation` 在 `result.isSuccess()==false` 和 throwable 两条路径均调 `postError` +- ✅ **取消反馈** — 失败时显示 Snackbar `cancel_failed` 替代静默吞没 + ### 待实现 -- 所有业务模块的 Controller/Service/Mapper/Entity 源码（📋 标注） -- library-security 的

security 71 + kg 3 + acquisition 10；bootstrap 1 项 @Disabled）。 + +- **P1 重要修复**：GlobalExceptionHandler 补 `DataIntegrityViolationException` handler（409 冲突响应）+ `spring-tx` 依赖；OperationLogAspect 分层合规——新建 `OperationLogService`/`OperationLogServiceImpl` 封装 Mapper，AOP 改注 Service 替代直接调 Mapper；GraphBuildServiceImpl `writeToNeo4j()` N+1 → UNWIND 批量写入（`batchMergeNodes`/`batchMergeRelationships`，从 >30 次往返降至 7 次固定调用）；清理 `EmbeddingServiceImpl` 未使用的 `MAX_RETRIES` 死代码；`fallbackNer()` 作者名分隔注释修正（正确反映不按空格分割西方全名）✅ +- **P2 实现质量优化**：RecommendationServiceImpl 超时后先收集部分结果再取消未完成任务（与日志一致）；ReservationZsetReconcileJob `ZRANGE 0 -1` → ZSCAN 分页（防大集合阻塞 Redis）；DuplicateCheckServiceImpl 输入标题 NLP 预处理提到循环外（消除 O(N) 次重复 tokenize）；NegotiationServiceImpl 注入 Spring `ObjectMapper` + `updateRecord` 接受已加载实体消除冗余

v1.13（对齐版本历史表，此前头部滞后于历史最新条目）；`docs/README.md` 目录结构示意图补阶段 9 两份文档条目（导航表已有、目录树遗漏）✅ +- **操作日志脱敏兑现**：`OperationLogAspect` 实现 `maskSensitive()`，对参数 JSON 中 password/passwd/secret/token/accessToken/refreshToken/credential/apiKey 等字段值脱敏为 `***`（兑现 `@OperationLog.logParams` Javadoc"敏感字段将由切面自动脱敏"的承诺，此前注释承诺但未实现）；新增 4 项单测覆盖，security 模块 71→75 ✅ +- **ES 重建批量优化**：`BookESRepository` 新增 `bulkSave(List)`（BulkRequest + `response.errors()` 部分失败检测）；`EsRebuildJob` 由逐条 `save` 改为先批量构建文档再 `bulkSave` 一次性写入（N 次网络往返→1 次），批量失败时降级逐条 `save` 隔离单条失败（阶段 9 后审计 P2-01 遗留）✅ +- **图谱事务边界澄清**：`GraphBuildServiceImpl.buildGraph()`/`rebuildAll()` 的 `@Transactional` 添加注释说明——其仅管理 MySQL 事务，而本方法无 MySQL 写操作（仅 select 读取），Neo4j 写入通过 Driver 独立 Session auto-commit 不在事务内、不可回滚；图谱一致性实际由 MERGE 幂等语义 + `KgBuildListener` 重试保证（消除 `@Transactional` 对 Neo4j 事务保护的误导）✅ +- **记录未改项**：`@ConditionalOnExpression` 在 `LlmConfig` @Bean 与 `LlmServiceImpl`/`EmbeddingServiceImpl` 类上重复声明同一 SpEL（阶段 9 后审计

单测）；`EmbeddingServiceImpl.batchEmbed` 批次间失败隔离（单批失败降级零向量，保证整体部分可用）；OpenAPI trace `{id}`→`{bookId}`、keypath `targetId`→`targetBookId` 契约对齐；架构文档 §2.3 用户管理权限注释"Admin 专有"→"Librarian 及以上"（对齐 `AdminUserController @RequireRole`）；**JWT 默认密钥 `dev-only-do-not-use-in-prod`（27 字节 < 32）触发 `@PostConstruct` fail-fast 致开发环境启动失败**——第一轮加固引入的回归，`application.yml` + `JwtProperties` 默认值改为 ≥32 字节 ✅ +- **P2 实现质量**：`BookUpdateDTO.totalCopies` 补 `@Min(1)`；`ReservationServiceImpl.batchLoadQueuePositions` `zRange 0 -1` 全量拉取→按用户 `rank` 逐条查询（防大集合阻塞 Redis）；`LlmServiceImpl`/`EmbeddingServiceImpl` `.block` 超时改为 `readTimeout×(maxRetries+1)+20s` 预算（修复重试被切断）；`LlmServiceImpl.onStatus` 统一 `isError()`；`Neo4jRepository` 新增 `ALLOWED_REL_TYPES`+`requireValidLabel/requireValidRelType` 在 `pageRank`/`saveNode`/`batchMerge*` 入口校验（与 `countNodes` 白名单对称）；`OperationLogAspect` 异步写入 `ForkJoinPool.commonPool`→注入 `taskExecutor`（手写构造器 + 测试同步 `Runnable::run`）；`KgRecommendQueryService` 删 `$topN`

开发默认密钥硬编码** | P0 | **仍为 P0** | 与实例数无关——密钥泄露或被猜测导致任何人均可签发 Token，是认证体系根基 | +| **CORS 默认回退 `"*"`** | P0 | **降为 P2** | 课设环境通常不涉及跨域攻击面，且单机部署；但答辩演示时配置遗漏仍可能被注意到 | +| **定时任务无分布式锁** | P0 | **降为 P3** | 单实例下 `@Scheduled` 天然互斥，不存在并发执行问题 | +| **OverdueCheckJob 收敛风险** | P1 | **降为 P2** | 单实例下 maxIterations=1000 兜底通常足够，但 SQL 逻辑缺陷（重复扫描同一批）仍存在 | +| **Reservation.setIfAbsent 空指针混淆** | P1 | **仍为 P1** | Redis 不可用时的误报与单/多实例无关，是代码逻辑缺陷 | +| **ES refresh=WaitFor** | P1 | **降为 P2** | 课设借阅量低，ES 写等待不会成为瓶颈 | +| **账户级登录失败锁定缺失** | P1 | **降为 P2** | 课设场景下撞库攻击低概率，但功能完整度上可加分 | +| **CF 全表内存矩阵** | P2 | **降为 P3** | 课设数据量（<1000 条借阅）完全在内存可承受范围内 | +| **evictAllSearchCache SCAN 集群问题** | P2 | **降为 P3** | 单实例 Redis 不存在此问题 | + +**结论**：在课设单实例场景下，上一版 P0 列表中仅 JWT 默认密钥（P0）与 Reservation 锁 null 路径混淆（P1）仍需作为必须修复项；其余 P0/P1 均可降级。**但需注意**：答辩老师可能因"代码健壮性"而扣分，建议在报告中标注设计意图并在代码注释中说明"课设单实例前提下省略分布式锁"。 + +### 1.2 当前安全措施对课设的充分性 + +| 措施 | 对课设意义 | 评价 | +|---|---|---| +| JWT 双 Token + Lua 原子轮换 + 重放检测 | 答辩加分项，展示了安全设计能力 | 优秀 | +| RBAC

3 种关系：`AUTHORED_BY`、`HAS_KEYWORD`、`BELONGS_TO`。 +- 搜索整个代码库中 `CITES` 的使用：仅在 `Neo4jRepository` 白名单、`LiteratureTracingServiceImpl` 查询、`GraphRelationType` 枚举中声明，但**没有任何构建代码会创建 CITES 边**。 +- 实体关系抽取（NER/RE）也只处理 AUTHORED_BY / HAS_KEYWORD / BELONGS_TO 三类，不包含引用关系。 +- 因此，即使用户通过 Admin 面板点击"重建知识图谱"（调用 `rebuildAll`），Neo4j 中也不会有任何 CITES 边，`trace()` 永远返回空 `paths`。 + +**结论**：文献溯源功能**代码完整但数据源缺失**。CITES 边需要从图书元数据（如参考文献字段）中提取，但当前系统未实现引用关系抽取逻辑。 + +#### 2.2.2 学科主题网络（`/kg/subject/{name}`） + +**代码链路**：[KnowledgeGraphController.java](file:///f:/CodeforJAVA/LibrarySystem-SIT/library-server/library-knowledge-graph/src/main/java/com/library/kg/controller/KnowledgeGraphController.java) →

计算并写入。但该方法**没有任何 API 端点触发**——Controller 没有对应接口，前端也没有按钮调用它。查询 `buildTopicNetwork` 的调用方，只在测试代码中出现过。 + +第二层：即使有 pagerank，也需要数据库中先有 Subject 节点，且 Subject 节点下有 Book 节点关联关键词。这需要：① 图书已通过 `buildGraph` 写入 Neo4j（创建 Book/Keyword/Subject 节点 + BELONGS_TO/HAS_KEYWORD 关系），② 需要学科分类名与 Neo4j 中 Subject 节点的 `name` 属性完全匹配。当前前端传递的 `name` 参数未知，可能与分类名不一致。 + +**结论**：学科主题网络功能**代码完整但无触发链**。需要手动调用 `buildTopicNetwork()` 生成 RELATED_TO 边和 PageRank 值，且需要图谱数据已存在。 + +#### 2.2.3 实体搜索（`/kg/search`） + +**代码链路**：[GraphQueryServiceImpl.searchEntities()](file:///f:/CodeforJAVA/LibrarySystem-SIT/library-server/library-knowledge-graph/src/main/java/com/library/kg/service/impl/GraphQueryServiceImpl.java#L96-L130)

LIMIT 50 +``` + +**根本原因**：**Neo4j 中没有任何节点**。 + +数据进入 Neo4j 的唯一路径是：图书创建/更新 → `BookCreatedEvent`/`BookUpdatedEvent` → `EventBusBridge` → RabbitMQ → `KgBuildListener` → `GraphBuildServiceImpl.buildGraph()` → 写入 Neo4j。 + +这条链路**代码完整**，但触发条件严格： +- 必须是**通过 API 创建或更新图书**（而非直接 INSERT 数据库），才会触发 Spring Event。 +- 如果用户用的是现有数据库数据（V100 种子或手动 SQL 插入），这些图书从未触发过 `BookCreatedEvent`，Neo4j 中不会有任何节点。 +- 如果 RabbitMQ 未启动，事件会进入 DLQ 而不会写入 Neo4j。 +- 如果 Neo4j 未启动，`KgBuildListener` 消费时会失败。 + +**解决方案**：Admin Dashboard 已有"重建知识图谱"按钮，点击后会调用 `POST /admin/kg/rebuild-all`，分页扫描所有 MySQL 图书并逐本 `buildGraph`。**但**此按钮需要以 ADMIN 角色登录才能看到，且需要 Neo4j 在线。 + +### 2.3 修复方案 + +| 功能 | 修复措施 | 工作量 | +|---|---|---| +| **文献溯源** | 在 `GraphBuildServiceImpl`
