根据模板生成代码的命令行工具（GoLang开发）
项目地址： https://github.com/lwydyby/generator-cli
前言
尽量少干活,让数据塑造代码;
依靠工具,把机制和策略分离
建设性懒惰是大师级程序员的基本美德之一(一切为了简化开(偷)发(懒)！)
开发的目的是减少业务开发中重复的复制粘贴工作，这里我写的example是针对spring boot + vue项目，其实对于其他项目，甚至其他语言，只要是可以归纳为一个模板，只是修改部分数据名称的需求都可以通过这个工具生成。
简介
$ genratorv1 --help
A code generator for spring boot program.
For example:
$ genratorv1 -f ./data.json
-t ./templates \
-o ./output
Usage:
genratorv1 [flags]
Flags:
-f, --file string setting文件及data文件所在位置
-o, --output string 输出到的文件夹.
-t, --template string 模板文件所在文件夹
-v, --version 版本信息
安装及使用
项目根目录存在mac上编译好的二进制文件（genratorv1） 其他系统请下载源码自行安装
源码安装步骤
$ git clone [email protected]:lwydyby/generator-cli.git
$ glide install
$ go install
说明
- setting.yaml
配置了模板名称和相应的输出文件名
template:
format: Go
template_files:
web:
file_path: web.tmpl
output_file_naming: index.vue
dao:
file_path: dao.tmpl
output_file_naming: userRepository.java
api:
file_path: api.tmpl
output_file_naming: user.js
service:
file_path: service.tmpl
output_file_naming: UserService.java
controller:
file_path: controller.tmpl
output_file_naming: UserController.java
entity:
file_path: entity.tmpl
output_file_naming: User.java
search:
file_path: search.tmpl
output_file_naming: UserSearch.java
- data.yaml
模板中所依赖的数据
data:
format: mongo
# 提供搜索功能的字段
search_column:
- prop: "name"
label: "名称"
type: "input"
- prop: "type"
label: "类型"
type: "select"
#创建时所需的字段
create_column:
- prop: "name"
type: "String"
label: "名称"
#列表展示的字段
table_column:
- prop: "name"
label: "名称"
type: "String"
#数据库中的名称
column_name: "name"
#除列表展示外数据库要保存的字段
extra_column:
- prop: "createDate"
type: "Date"
label: "创建日期"
column_name: "create_date"
#按钮及表单名
button_name: "用户"
#生成的英文名
name: "User"
package: "com.example"
- *.tmpl
下面展示了生成vue的模板，其余模板请参照templates/example
