lingniu-dev 064ecc479c chore: initial import of lingniu-vehicle-ingest
Multi-module Spring Boot ingest service for vehicle telemetry. Modules:

- ingest-api / ingest-core / ingest-codec-common: shared SPI, dispatcher,
  Disruptor event bus, BCC/BCD codec helpers
- protocol-gb32960: GB/T 32960.3 inbound (Netty + per-version parser
  packages v2016/v2025), platform login auth, VIN whitelist, idle handler
- protocol-jt808 / protocol-jt1078 / protocol-jsatl12: JT/T inbound
- inbound-mqtt / inbound-xinda-push: alternative ingest channels
- session-core: per-channel session state
- sink-archive / sink-mq: persistence sinks (local file / Kafka)
- command-gateway: terminal control command gateway
- bootstrap-all: aggregator Spring Boot app
- observability: Micrometer / Actuator wiring

Includes hex-dump golden samples under protocol-gb32960/src/test/resources
and the GB/T 32960.3-2016 / 2025 reference PDFs under reference/.

# lingniu-vehicle-ingest
> 羚牛车辆数据接入平台 v2
## 设计目标
- **协议接入统一抽象**GB/T 32960、JT/T 808、JT/T 1078、JSATL12、MQTT、信达 Push 全部变成可插拔 Inbound Adapter
- **原子能力化**:每个协议一个独立 Maven 模块 + 独立 AutoConfiguration + 独立配置开关
- **业务 / 实时彻底解耦**:本服务只负责 **收 → 解析 → 校验 → 规整 → 投递 Kafka**,不碰业务库
- **高并发低延迟**Netty + Disruptor + Java 25 虚拟线程;目标单节点 ≥ 5 万 msg/sP99 < 50 ms
- **可观测、可回放、可灰度**:统一 traceId、Envelope、幂等键、DLQ、原始报文冷存
## 技术栈
| 类别 | 选型 |
|---|---|
| 语言 | Java **25** |
| 框架 | Spring Boot 3.4.x |
| 网络 | Netty 4.1 |
| 并发 | Disruptor 4 + 虚拟线程 + `StructuredTaskScope` |
| 消息队列 | **Kafka**vin 分区,保证单车有序) |
| 线上消息格式 | **Protobuf**,调试走 JSON |
| MQTT 客户端 | HiveMQ MQTT Client |
| 会话缓存 | Caffeine + Redis 兜底 |
| 熔断/限流 | Resilience4j 2 |
| 可观测 | Micrometer + Prometheus + OpenTelemetry |
| 冷存 | S3 / OSS / 本地 |
| 构建 | Maven + Spotless + ArchUnit |

## 快速开始
```bash
# 要求JDK 25, Maven 3.9+
mvn -v
mvn clean install -DskipTests
cd bootstrap-all && mvn spring-boot:run
```
## 迁移说明
本项目是 `lingniu-vehicle-data-reception` 的 v2 重构,采用 strangler fig 渐进式迁移,旧项目保留只读参考。迁移路径与决策参见 `../REFRACTOR_PLAN.md`
## 核心原则
1. **本服务不写业务库**:历史、行程、在线检测、里程统计全部由 Kafka 下游消费者实现
2. **协议即插拔**:每个 `protocol-*` / `inbound-*` 都可独立开关(`lingniu.ingest.<name>.enabled`
3. **顺序保证**:同一 VIN 严格有序Disruptor hash + Kafka 分区 key
4. **幂等消费**Envelope 带 `eventId`,下游去重
5. **原始可回放**`vehicle.raw.archive` topic + 对象存储
