- 应用骨架: Solon + MyBatis-Plus + PostgreSQL + Redis + Sa-Token - 核心链路: 回调网关 → 消息落库(幂等) → 分发队列(FOR UPDATE SKIP LOCKED) → worker消费/重试/死信 - 多租户隔离: 前缀法账号映射, 所有业务表带 tenant_id - 管理后台: FreeMarker 渲染, 租户/授权/队列/用量管理页面 - 历史消息补拉: 水位线驱动, getRoamMsg/getGroupMsg 增量拉取, 兜底回调丢失 - msg_key 统一算法(回调/补拉共享, 跨路径去重) Co-Authored-By: Claude <noreply@anthropic.com>
