4. 分析结论 ### 4.1 活跃事件(有发布+有消费):11 个 这是系统核心业务链路,全部正常: - `workflow.task.completed` → 随访自动完成 - `device.readings.synced` → 告警评估 - `alert.triggered` → 告警通知 - `patient.created` → 欢迎消息 - `appointment.confirmed/cancelled` → 预约通知 - `follow_up.overdue` → 逾期升级 - `health_data.critical_alert` → 危急值告警 - `ai.analysis.completed` → 医生通知 - `dialysis.record.created` → 日志 - `consent.granted/revoked` → 知情同意通知 ### 4.2 有发布无消费事件:14 个 这些事件被发布到 EventBus 并持久化到 domain_events 表,但没有业务消费者。它们可能仅用于审计追踪或 SSE 前端推送。 **风险评估**: | 事件 | 风险 | 说明 | |------|------|------| | `patient.updated` | LOW | 信息性事件,更新操作已直接处理 | | `vital_signs.created` | LOW | 数据已写入 DB,无需后续触发 | | `lab_report.uploaded` | LOW | 同上 | | `lab_report.reviewed` | LOW | 同上 | | `follow_up.created` | LOW | 任务已创建,无需后续触发 | | `follow_up.completed` | LOW | 状态已更新,无需后续触发 | | `consultation.*` | LOW | 会话管理已在 service 内直接处理 | | `article.published/rejected` | LOW | 状态已更新,无需后续触发 | | `points.earned/exchanged/expired` | LOW | 积分操作已在 service 内完成 | | `daily_monitoring.created` | LOW | 数据已写入 | | `doctor.online_status_changed` | LOW | 状态已更新 | ### 4.3 已知未实现事件(KNOWN):2 个 - `PATIENT_VERIFIED` — 患者认证流程未实现 - `PATIENT_DECEASED` — 死亡记录流程未实现 ### 4.4 潜在问题 1. **message.sent 消费者仅为日志记录** — event.rs:119 的消费者仅做 tracing::info,实际业务逻辑(如更新 consultation last_message_at)已在 service 层直接处理,此消费者预留扩展但当前无实质作用。 2. **SSE 全事件转发** — erp-message 的 SSE handler 监听所有事件,意味着所有事件(包括 points.earned 等低优先级事件)都会被推送到前端,可能导致通知噪音。 --- ## 5. Payload Schema 一致性验证(抽样 5 个) | 事件 | 发布方字段 | 消费方解析 | 一致性 | |------|-----------|-----------|--------| | `workflow.task.completed` | `task_id` | `task_id` → Uuid | ✅ | | `device.readings.synced` | `patient_id` | `patient_id` → Uuid | ✅ | | `health_data.critical_alert` | `patient_id, alert_type, metric_name, metric_value, threshold_value` | 全部解析 | ✅ | | `follow_up.overdue` | `task_id, assigned_to` | 全部解析 | ✅ | | `appointment.confirmed` | `doctor_id, patient_id` | 全部解析 | ✅ | **结论**:所有抽样的关键事件 payload schema 发布方与消费方完全一致。所有消费者都使用幂等检查(`is_event_processed`),防止重复处理。 --- ## 6. 事件系统评分 | 检查项 | 评分 | 说明 | |--------|------|------| | 事件定义完整性 | 95% | 25/27 常量有发布者(2 个 KNOWN 未实现) | | 消费者覆盖率 | 44% | 11/25 事件有活跃消费者 | | Payload 一致性 | 100% | 抽样 5 个全部一致 | | 幂等性保证 | 100% | 所有消费者使用 `is_event_processed` 检查 | | 死信处理 | 100% | 消费失败自动进入 dead_letter_event 表 |
