### gorm mysql数据库转 struct 工具,可以将mysql数据库自动生成golang sturct结构，带大驼峰命名规则。带json标签
|
|
|
|
|
|
|
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
|
|
## 1. 通过当前目录config.toml文件配置默认配置项
|
|
|
|
|
|
```
|
|
|
|
|
|
out_dir = "." # 输出目录
|
|
|
|
|
|
singular_table = false # 表名复数,是否大驼峰构建 参考:gorm.SingularTable
|
|
|
|
|
|
simple = false #简单输出
|
|
|
|
|
|
isJsonTag = true #是否打json标记
|
|
|
|
|
|
[mysql_info]
|
|
|
|
|
|
host = "127.0.0.1"
|
|
|
|
|
|
port = 3306
|
|
|
|
|
|
username = "root"
|
|
|
|
|
|
password = "qwer"
|
|
|
|
|
|
database = "oauth_db"
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
## 2. 可以使用命令行工具更新配置项
|
|
|
|
|
|
```
|
|
|
|
|
|
./gormt -H=127.0.0.1 -d=oauth_db -p=qwer -u=root --port=3306
|
|
|
|
|
|
```
|
|
|
|
|
|
## 3. 查看帮助
|
|
|
|
|
|
```
|
|
|
|
|
|
./gormt --help
|
|
|
|
|
|
or
|
|
|
|
|
|
./gormt -h
|
|
|
|
|
|
|
|
|
|
|
|
-------------------------------------------------------
|
|
|
|
|
|
base on gorm tools for mysql database to golang struct
|
|
|
|
|
|
|
|
|
|
|
|
Usage:
|
|
|
|
|
|
main [flags]
|
|
|
|
|
|
|
|
|
|
|
|
Flags:
|
|
|
|
|
|
-d, --database string 数据库名
|
|
|
|
|
|
-h, --help help for main
|
|
|
|
|
|
-H, --host string 数据库地址.(注意-H为大写)
|
|
|
|
|
|
-o, --outdir string 输出目录
|
|
|
|
|
|
-p, --password string 密码.
|
|
|
|
|
|
--port int 端口号 (default 3306)
|
|
|
|
|
|
-s, --singular 是否禁用表名复数
|
|
|
|
|
|
-u, --user string 用户名.
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 4. 支持gorm 相关属性
|
|
|
|
|
|
|
|
|
|
|
|
- 数据库表,列字段注释支持
|
|
|
|
|
|
- singular_table 表名复数(大驼峰)
|
|
|
|
|
|
- json tag json标签输出
|
|
|
|
|
|
- gorm.Model 基本模型
|
|
|
|
|
|
- PRIMARY_KEY 将列指定为主键
|
|
|
|
|
|
- UNIQUE 将列指定为唯一
|
|
|
|
|
|
- NOT NULL 将列指定为非 NULL
|
|
|
|
|
|
- INDEX 创建具有或不带名称的索引, 如果多个索引同名则创建复合索引
|
|
|
|
|
|
- UNIQUE_INDEX 和 INDEX 类似，只不过创建的是唯一索引
|
|
|
|
|
|
|
|
|
|
|
|

## 6. 下一步计划
|
|
|
|
|
|
|
|
|
|
|
|
- 加入外键支持(ForeignKey)
