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 git@github.com: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
