# 编码生成功能 实现计划
|
|||
|
|
|
|||
|
|
> **面向 AI 代理的工作者：** 必需子技能：使用 superpowers:subagent-driven-development（推荐）或 superpowers:executing-plans 逐任务实现此计划。步骤使用复选框（`- [ ]`）语法来跟踪进度。
|
|||
|
|
|
|||
|
|
**目标：** 在 nl-module-base 模块下实现编码生成引擎，支持 PREFIX + DATE + SEQUENCE 三段组合、号段预分配/分布式锁两种并发策略、规则配置化管理。
|
|||
|
|
|
|||
|
|
**架构：** 编码规则通过 `base_code_rule` 表存储（分段配置用 JSON），流水号段用 `base_code_sequence` 表记录。核心引擎 `CodeGenServiceImpl` 遍历分段配置逐段生成，`SequenceAllocator` 负责号段的分布式并发分配（Lock4j + 内存缓存 + DB 预取）。规则查询使用 Redis 缓存（30 分钟 TTL），更新时主动清除。
|
|||
|
|
|
|||
|
|
**技术栈：** Java 17 + Spring Boot 3 + MyBatis-Plus + Lock4j (baomidou) + Redis (StringRedisTemplate) + Jackson JSON + MySQL

号段预分配：

1. 使用 INSERT ... ON DUPLICATE KEY 实现"不存在则插入，存在则更新"

2. 利用 idx_rule_reset (rule_id, reset_key) 唯一性校验并发安全

3. 首次插入时 current_value = startAt + step - 1，后续更新时 current_value = current_value + step
|

注意：此 SQL 依赖 idx_rule_reset 索引配合行锁，需在 Lock4j 保护下调用

## 自检清单
|
|||
|
|
|
|||
|
|
**1. 规格覆盖度：**
|
|||
|
|
- ✅ 三种段类型（PREFIX/DATE/SEQUENCE）— 任务 3（DTO）+ 任务 10（引擎）
|
|||
|
|
- ✅ 序号控制（按天/月/年重置、补位、最大值）— 任务 9（SequenceAllocator）
|
|||
|
|
- ✅ 格式自定义（分隔符、大小写、总长度）— 任务 6（VO）+ 任务 10（引擎）
|
|||
|
|
- ✅ 并发唯一性（号段预分配 + Lock4j）— 任务 9（SequenceAllocator）
|
|||
|
|
- ✅ 规则管理 CRUD + 缓存 — 任务 8（Service）+ 任务 11（Controller）
|
|||
|
|
- ✅ 对外 Feign API — 任务 7（API）+ 任务 12（Controller）
|
|||
|
|
|
|||
|
|
**2. 占位符扫描：** 无 TODO、无占位，通过 ✅
|
|||
|
|
|
|||
|
|
**3. 类型一致性：**
|
|||
|
|
- `SegmentConfig` 及其子类的 Jackson 多态配置与 `CodeRuleDO.segmentConfig` 的 `JacksonTypeHandler` 匹配 ✅
|
|||
|
|
- `CodeRuleSaveReqVO.segments` 使用 `List<SegmentConfig>` 与 DO 一致 ✅
|
|||
|
|
- `SequenceAllocator.allocateBySegment()` 签名与 `CodeGenServiceImpl.buildSequenceSegment()` 调用匹配 ✅
|
|||
|
|
- Controller 路径与设计规格一致 ✅
