JeecgBoot 代码生成器(Freemarker 驱动)
把用户的自然语言需求转成 Freemarker 上下文 JSON,交给 scripts/codegen.py 调用模板生成全套 CRUD(后端 Java + 前端 Vue3 + 菜单 SQL)。
核心原则
AI 不再从零写代码。 基础代码全部由 jeecg 官方 Freemarker 模板生成,AI 只做三件事:
- 拼参数 — 把用户需求映射成
ctx.json- 调脚本 — 跑
scripts/codegen.py让 Freemarker 出基础代码- 改产物 — 用户提了模板不覆盖的特殊需求时,用 Edit 改已生成的代码
⛔ 禁止修改
templates/目录下任何模板文件。模板由 jeecg 官方维护,改了就脱离了升级路径。 ⛔ 禁止绕开脚本直接手写 Entity / Controller / data.ts 等基础文件。
主数据复用
涉及字典、角色、用户、部门时遵循"先查后建",使用 jeecg-system skill。详见 ../jeecg-system/SKILL.md。
接口禁止猜测
所有接口路径/参数必须来自用户提供、jeecg-system skill 文档、或经查询确认。猜测命中也算违规。
模板覆盖范围
不是所有"表类型 × 前端风格"的组合都有模板。先选表类型 → 决定可选的前端风格:
| 表类型 | 模板 stylePath | 支持前端风格 | 触发关键词 |
|---|---|---|---|
| 单表 | default/one | vue3 vue3Native | 默认 |
| 树表 | default/tree | vue3 vue3Native | 分类/层级/树/上下级 |
| 一对多 — Tab-in-Modal | tab/onetomany | vue3 | tab风格 / radio切换 / 标题栏切换 |
| 一对多 — 内嵌子表 | inner-table/onetomany | vue3 | 内嵌子表 / 行展开 / expandedRowRender |
| 一对多 — ERP | erp/onetomany | vue3 vue3Native | ERP风格 / 独立编辑 |
不支持的组合: 一对多 + 默认布局(即旧 SKILL 中的"原始布局")目前没有 vue3 模板,jeecg 官方枚举
CgformEnum.MANY仅支持 vue2。 如果用户要"默认/原始布局"的 vue3 一对多,改推荐tab或inner-table,并向用户说明原因。
交互流程
Step 0 — 判断操作类型
- 关键词 "加字段 / 删字段 / 改字段 / 给XX加" → 增量修改(跳到本文末"增量修改"章节)
- 其他 → 全量生成
Step 1 — 收集参数(一次性问完)
⛔ **铁律:**Step 2 摘要被用户明确确认前,禁止调脚本、禁止落地任何文件、禁止执行任何 SQL。 "需求很清楚了""都用默认值""先生成再改" 都是合理化跳过确认的借口,全部无效。
向用户一次问全所有缺失项(已知项可填默认值并标注"如无异议保留"):
| 项 | 默认值 / 提示 |
|---|---|
| 后端模块根 | <backend_root>(如 D:/jeecgboot/jeecg-module-system/jeecg-system-biz) |
| 前端项目根 | <frontend_root>(如 D:/jeecgboot-vue3) |
| Flyway SQL 目录 | <backend>/jeecg-module-system/jeecg-system-start/src/main/resources/flyway/sql/mysql |
| bussiPackage | org.jeecg.modules |
| entityPackage | 由用户给(如 biz / edu) |
| entityName / tableName | 由用户给或推导(如 BizGoods / biz_goods) |
| 描述(中文) | 用户业务名(如"商品管理") |
| 表类型 | 单表 / 树表 / 一对多 |
| 一对多风格 | 仅一对多需要:tab / inner-table / erp |
| 前端风格 | vue3 或 vue3Native(结合表类型用上表校验是否支持) |
| 字段清单 | 已有表 → 查 DDL 自动取;新建表 → 由用户描述 |
| 字典自动匹配 | 默认是。开启后会查 sys_dict 自动套字典编码(见下方"字典匹配") |
| 目标数据库名 | 仅"已有表/字典查询/本地执行 SQL"时需要,必须由用户确认 |
Step 2 — 展示摘要
把构造好的 ctx.json 用表格展示给用户:
- 表头:表名、实体名、风格、前端风格、字段数
- 字段表:fieldName / fieldDbName / 注释 / fieldDbType / classType / 字典 / 必填 / 列表显示 / 表单显示 / 查询
- 不要 dump 整个 JSON,太冗长
明确询问 "是否生成?" — 收到 "确认 / ok / 可以 / 没问题" 等表述后才进入 Step 3。
Step 3 — 调用脚本
调用前先把构造好的 JSON 写到临时目录(路径规则见下方"临时配置文件规则"),然后用绝对路径调脚本。
SKILL 路径定位: 脚本永远在 <SKILL_ROOT>/scripts/codegen.py。<SKILL_ROOT> 就是包含 SKILL.md 的那个目录,比如 C:\Users\moe\.claude\skills\jeecg-codegen-new 或 E:\Projects\BJGJ\jeecg-skills\jeecg-codegen-new——你能加载 SKILL.md 就能得出这个路径,不要再去 Read codegen.py 来确认任何东西,下面的 CLI 参考就是脚本的完整契约。
完整 CLI 参考
python <SKILL_ROOT>/scripts/codegen.py [OPTIONS]
| 参数 | 必填 | 默认 | 取值 | 说明 |
|---|---|---|---|---|
--style | ✅ | — | default/one default/tree default/onetomany tab/onetomany inner-table/onetomany erp/onetomany | 模板风格,见"模板覆盖范围"表 |
--ctx | ✅ | — | 文件路径 | ctx.json 路径,必须在 {tempdir}/jeecg-codegen-new/<表名>_ctx.json |
--frontend-style | 🟡 | vue3 | vue3 vue3Native | 必须与 --style 兼容,否则脚本拒绝(详见"模板覆盖范围"表) |
--backend-root | 🟡 | — | 后端模块根 | 比如 D:/jeecgboot/jeecg-module-system/jeecg-system-biz,脚本会自动拼 /src/main/java/<bussiPackage>/<entityPackage>/ |
--frontend-root | 🟡 | — | 前端项目根 | 比如 D:/jeecgboot-vue3,脚本会自动拼 /src/views/<entityPackage>/ |
--mobile-root | ❌ | — | uniapp 项目根 | 不传则跳过 uniapp/uniapp3 产物——常规需求都不需要传 |
--flyway-dir | 🟡 | — | Flyway SQL 目录 | 菜单 SQL 落到这里;同名 SQL 自动去重 |
--out | ❌ | — | 任意目录 | 调试用:渲染产物原样落到此目录,跳过分发。设了它就不需要 backend/frontend/flyway-root |
--dry-run | ❌ | false | flag | 打印分发计划但不写文件 |
🟡 = 在没有
--out的"正常模式"下,至少要传--backend-root或--frontend-root或--flyway-dir之一(任何没传的目录类型对应的产物都被跳过);正常代码生成场景三个都该传。✅ = 任何模式都必填。
退出码 & 输出
- 退出码
0= 成功;其他都失败(参数非法、Java 编译失败、Freemarker 渲染异常) - 标准输出每行一个事件:
[codegen] WROTE <绝对路径>、[codegen] WOULD WRITE ...(dry-run 时)、[codegen] running FtlRunner …等 - 失败时 stderr 含完整 Java 栈或
[codegen] xxx错误信息
典型调用(复制后改 4 个值即可)
python E:/Projects/BJGJ/jeecg-skills/jeecg-codegen-new/scripts/codegen.py \
--style default/one \
--ctx /c/Users/moe/AppData/Local/Temp/jeecg-codegen-new/biz_goods_ctx.json \
--backend-root D:/jeecgboot/jeecg-module-system/jeecg-system-biz \
--frontend-root D:/jeecgboot-vue3 \
--frontend-style vue3 \
--flyway-dir D:/jeecgboot/jeecg-module-system/jeecg-system-start/src/main/resources/flyway/sql/mysql
临时配置文件规则(强制)
所有传给脚本的 --ctx <xxx.json> 必须写到 {系统临时目录}/jeecg-codegen-new/ 下,由操作系统自动清理;skill 与脚本均不主动删除该目录或文件。
import tempfile, os, json
SKILL_NAME = "jeecg-codegen-new"
skill_dir = os.path.join(tempfile.gettempdir(), SKILL_NAME)
os.makedirs(skill_dir, exist_ok=True) # 确保目录存在,不主动检查
config_path = os.path.join(skill_dir, 'biz_goods_ctx.json') # 示例文件名:<表名>_ctx.json
with open(config_path, 'w', encoding='utf-8') as f:
json.dump(cfg, f, ensure_ascii=False, indent=2)
tempfile.gettempdir() 自动适配:Windows %TEMP%、Linux /tmp、macOS /var/folders/.../T(注意 macOS 并非 /tmp)。
文件名建议使用 <表名>_<步骤>.json(如 biz_goods_ctx.json / biz_goods_alter.json),无需重复技能前缀,因路径已包含技能名称,便于排错。
❌ 禁止:
- 写到
<skill>/tmp/或当前工作目录(污染 skill / 用户项目) - 硬编码
/tmp、C:\Temp或任何固定路径(不跨平台) - 每步完成后主动
rm/Remove-Item(操作系统会清理,属多余 tool call) - 主动
os.path.exists()检查(其本身即为一次 tool call) (使用os.makedirs(…, exist_ok=True)满足需求,不算主动检查)
临时文件可能被操作系统异步清理,但仍遵循 乐观调用 + 报错补救:仅当脚本返回 FileNotFoundError 或 配置文件不存在 时,使用相同内容、在相同的 {系统临时目录}/jeecg-codegen-new/ 路径下重写(重写前仍需 os.makedirs(skill_dir, exist_ok=True) 确保目录存在),切勿更换路径或回退至 skill 目录。
Step 4 — 处理特殊需求(模板没覆盖的部分)
用户的需求经常超出模板能力(比如"商品名要带前缀生成""价格变更后自动算总价""列表行加复制按钮"),这时:
- 先跑脚本生成基础代码
- 再用 Read 读出对应文件、用 Edit 做精细修改
- 不要改 templates/,永远改产物
常见的特殊需求与改动位置参考 references/post-edit-recipes.md。
Step 5 — 后续操作
- Flyway SQL:脚本已落到
<flyway-dir>/V<date>_1__menu_insert_<entity>.sql,重启后端时 Flyway 自动执行;如果用户要求立即生效,按"本地自动执行 SQL"流程做(见下方)。 - 重启后端:提示用户
mvn spring-boot:run -pl jeecg-module-system/jeecg-system-start - 前端热更新:
pnpm dev自动热更,无需重启 - 菜单可见:默认授权 admin,登录系统直接可见
字段语义推导
新建表时,AI 需要把用户描述的字段(如"价格"、"备注")映射到合适的 classType / fieldDbType / fieldType。映射表见 references/field-mapping.md。
已有表场景下,从 DDL 直接读类型,不依赖语义推导。
已有表反向生成
用户给了表名 → 必须先查数据库取 DDL 再构造 ctx:
# 询问用户目标数据库名后,一条命令拿全部信息
mysql --no-defaults --default-character-set=utf8mb4 -h127.0.0.1 -P3306 -uroot -proot {dbname} \
-e "SHOW CREATE TABLE 表名\G" \
-e "SELECT COLUMN_NAME, COLUMN_TYPE, IS_NULLABLE, COLUMN_DEFAULT, COLUMN_COMMENT, COLUMN_KEY, EXTRA FROM information_schema.COLUMNS WHERE TABLE_SCHEMA='{dbname}' AND TABLE_NAME='表名' ORDER BY ORDINAL_POSITION"
⛔ 执行任何 SQL 前必须先询问用户目标数据库名,不要从 application-dev.yml 自动取——用户本机可能多库并存。
字典自动匹配
用户开启后,先查全部字典:
mysql ... -e "
SELECT d.dict_code, d.dict_name,
GROUP_CONCAT(i.item_text, '=', i.item_value ORDER BY i.sort_order SEPARATOR ', ') AS items
FROM sys_dict d LEFT JOIN sys_dict_item i ON d.id = i.dict_id AND i.status = 1
WHERE d.del_flag = 0 GROUP BY d.dict_code, d.dict_name ORDER BY d.dict_code"
匹配优先级:用户明确指定 > 字段名等于 dict_code > 注释关键词命中 dict_name > 不匹配。
匹配后在 ctx 的 column 上设置 classType: "list" + dictField: "<dict_code>",模板会自动展开成 @Dict + JDictSelectTag + dataIndex: "fieldName_dictText" 等完整代码。
更详细见 references/dict-matching.md。
本地自动执行菜单 SQL(仅 127.0.0.1 / localhost)
用户确认目标数据库后:
# 1. 检查主菜单是否已存在(避免重复插入)
mysql ... -e "SELECT id FROM sys_permission WHERE name='<描述>' AND parent_id IS NULL"
# 2. 不存在则执行
mysql ... < <flyway_sql_file_path>
执行失败时只提示,不中断流程——Flyway 文件已落地,下次重启会自动执行。
增量修改(加 / 删 / 改字段)
所有"模板已生成的代码 + 用户后续小调整"都走 Edit,不重新跑脚本。
Step A — 定位文件
# Entity
find <backend_root>/src/main/java -name "<EntityName>.java"
# 前端 data.ts
find <frontend_root>/src/views -name "<EntityName>__data.ts"
需要读:Entity.java / *__data.ts / *List.vue / *Modal.vue / *Form.vue(vue3Native)。
Step B — 推导新字段属性
参考 references/field-mapping.md。
Step C — 展示摘要 → 等用户确认 → 执行 Edit
加字段:在所有相关文件追加;删字段:精确删除;改字段:定位修改。 ALTER TABLE 写到新的 Flyway SQL(版本号递增)。
不要因为"加一个字段"就重新跑全量代码生成,会覆盖用户对生成结果的手工修改。
文件夹与脚本
| 路径 | 说明 |
|---|---|
templates/ | jeecg 官方 Freemarker 模板(只读) |
lib/ | freemarker.jar + fastjson2.jar |
scripts/codegen.py | 主入口(Python3) |
scripts/FtlRunner.java | Java 渲染器(首次运行自动 javac) |
scripts/.cache/ | 编译产物 + 临时 ctx |
references/field-mapping.md | 字段语义 → Freemarker 字段映射 |
references/context-schema.md | ctx.json 完整 schema |
references/post-edit-recipes.md | 模板没覆盖的特殊需求改动位置 |
references/dict-matching.md | 字典匹配规则与 ctx 映射 |
依赖:java(JDK 8+)+ python3(3.9+,类型注解用了 PEP 585 语法)。脚本会自动探测 javac 版本:JDK 8 用 -source 8 -target 8,JDK 9+ 用 --release 8,最终编译产物始终为 Java 8 字节码(major=52)。

## 增量修改(加 / 删 / 改字段)
> 所有"模板已生成的代码 + 用户后续小调整"都走 Edit,不重新跑脚本。
### Step A — 定位文件
```bash
# Entity
find <backend_root>/src/main/java -name "<EntityName>.java"
# 前端 data.ts
find <frontend_root>/src/views -name "<EntityName>__data.ts"
```
需要读:`Entity.java` / `*__data.ts` / `*List.vue` / `*Modal.vue` / `*Form.vue`(vue3Native)。
### Step B — 推导新字段属性
参考 `references/field-mapping.md`。
### Step C — 展示摘要 → 等用户确认 → 执行 Edit
加字段:在所有相关文件追加;删字段:精确删除;改字段:定位修改。
ALTER TABLE 写到新的 Flyway SQL(版本号递增)。
> 不要因为"加一个字段"就重新跑全量代码生成,会覆盖用户对生成结果的手工修改。

## 文件夹与脚本
| 路径 | 说明 |
|---|---|
| `templates/` | jeecg 官方 Freemarker 模板(**只读**)|
| `lib/` | freemarker.jar + fastjson2.jar |
| `scripts/codegen.py` | 主入口(Python3)|
| `scripts/FtlRunner.java` | Java 渲染器(首次运行自动 javac)|
| `scripts/.cache/` | 编译产物 + 临时 ctx |
| `references/field-mapping.md` | 字段语义 → Freemarker 字段映射 |
| `references/context-schema.md` | ctx.json 完整 schema |
| `references/post-edit-recipes.md` | 模板没覆盖的特殊需求改动位置 |
| `references/dict-matching.md` | 字典匹配规则与 ctx 映射 |
依赖:`java`(JDK 8+)+ `python3`(3.9+,类型注解用了 PEP 585 语法)。脚本会自动探测 javac 版本:JDK 8 用 `-source 8 -target 8`,JDK 9+ 用 `--release 8`,最终编译产物始终为 Java 8 字节码(major=52)。
