# jupiter ## 脚手架介绍 ### jupiter脚手架工具集 1. 快速生成模板项目 2. 基于proto文件生成pb.go 3. 基于proto文件生成服务端实现 # go version GO >= 1.13 ## 脚手架工具获取 windows : ```shell script set GO111MODULE=on set GOPROXY=https://mirrors.aliyun.com/goproxy/,direct ``` linux : ```shell script export GO111MODULE=on export GOPROXY=https://mirrors.aliyun.com/goproxy/,direct ``` `go get -u -v github.com/douyu/jupiter/tools/jupiter` * windows 用户: 会在${GOPATH}/src/bin 目录下生成jupiter.exe 文件,若想方便的在任何地方使用jupiter命令,请将该 命令配置在系统的环境变量中 * Linux 用户: * Mac 用户 : ## 如何使用 * jupiter -h ```shell script E:\go\goworkspace\src\jupiter-demo\cmd>jupiter -h NAME: jupiter - jupiter tools USAGE: jupiter [global options] command [command options] [arguments...] VERSION: 0.1.0 COMMANDS: new, n Create Jupiter template project protoc, p jupiter protoc tools help, h Shows a list of commands or help for one command GLOBAL OPTIONS: --help, -h show help --version, -v print the version ``` * jupiter new -h ```shell script E:\go\goworkspace\src\jupiter-demo\cmd>jupiter new -h NAME: jupiter new - Create Jupiter template project USAGE: jupiter [commands|flags] The commands & flags are: new Create Jupiter template project -d Build the specified directory for the template project Examples: # Build the specified directory for the template project jupiter new (your project name) -d (project dir) ``` * jupiter protoc -h ```shell script E:\go\goworkspace\src\jupiter-demo\cmd>jupiter protoc -h NAME: jupiter protoc - jupiter protoc tools USAGE: jupiter [commands|flags] The commands & flags are: protoc jupiter protoc tools -g,--grpc whether to generate GRPC code -s,--server whether to generate grpc server code -f,--file path of proto file -o,--out path of code generation -p,--prefix prefix(current project name) Examples: # Generate GRPC code from the Proto file # -f: Proto file address -o: Code generation path -g: Whether to generate GRPC code jupiter protoc -f ./pb/hello/hello.proto -o ./pb/hello -g # According to the proto file, generate the server implementation # -f: Proto file address -o: Code generation path -p:prefix(Current project name) -g: Whether to generate Server code jupiter protoc -f ./pb/hello/hello.proto -o ./internal/app/grpc -p jupiter-demo -s ``` ## 开始实战 接下来我们会一步一步的带着大家从无到有开发jupiter应用!(gopher Let's go) ### 快速创建jupiter模板项目 ```shell script cd ${GOPATH}/src jupiter new jupiter-demo -d ./ ``` 命令解释: * new :创建jupiter模板项目 * jupiter-demo: 项目名称 * -d: 生成项目所在路径 然后就会在${GOPATH}/src 下生成jupiter-demo 项目 项目目录结构: ```go build 编译目录 cmd 应用启动目录 config 应用配置目录 internal ├─app 应用目录 │ ├─engine │ │ ├─engine.go 核心编排引擎(启动HTTP,GRPC,JOB等服务) │ ├─grpc grpc服务实现目录 │ ├─handler 控制器目录（接收用户请求） │ │ ├─user.go 控制器文件 │ ├─model model目录（定义持久层结构体） │ │ ├─db │ │ │ ├─user.go │ │ ├─init.go 初始化全局数据库句柄 │ ├─service service层 │ │ ├─user 模块 │ │ │ ├─impl │ │ │ │ ├─mysqlImpl.go 实现 │ │ │ ├─repository.go service 接口 │ │ ├─init.go pb proto文件 sql sql脚本 .gitignore go.mod Makefile ``` ### 运行jupiter应用 * 数据库环境准备 1. 请先在mysql中创建test库，然后将sql中的user.sql在该库中执行 2. 修改mysql配置: 在config/config.toml中 找到 `[jupiter.mysql.test]` 将`dsn` 改成你所在的环境 * 下载go.mod依赖 * 编译运行 在项目跟目录下执行以下命令 ```shell script cd cmd go run main.go --config=../config/config.toml ``` 接下来你将会看到以下日志 ```shell script E:\go\goworkspace\src\jupiter-demo\cmd>go run main.go --config=../config/config.toml (_)_ _ _ __ (_) |_ ___ _ __ | | | | | '_ \| | __/ _ \ '__| | | |_| | |_) | | || __/ | _/ |\__,_| .__/|_|\__\___|_| |__/ |_| Welcome to jupiter, starting application ... 1592274902 INFO load local file {"mod": "config", "addr": "../config/config.toml"} 1592274902 INFO auto max procs {"mod": "proc", "procs": 4} 1592274902 INFO set global tracer {"mod": "trace"} 1592274902 INFO add job {"mod": "worker.cron", "name": "jupiter-demo/internal/app/engine.(*Engine).execJob-fm"} ?[33m[2020-06-16 10:35:02]?[0m ?[35m[info] replacing callback `gorm:delete` from E:/go/goworkspace/src/jupiter-demo/vendor/github.com/douyu/jupiter/pkg/store/gorm/orm.go:118?[0m ?[31;1m ?[0m ?[33m[2020-06-16 10:35:02]?[0m ?[35m[info] replacing callback `gorm:update` from E:/go/goworkspace/src/jupiter-demo/vendor/github.com/douyu/jupiter/pkg/store/gorm/orm.go:118?[0m ?[31;1m ?[0m ?[33m[2020-06-16 10:35:02]?[0m ?[35m[info] replacing callback `gorm:create` from E:/go/goworkspace/src/jupiter-demo/vendor/github.com/douyu/jupiter/pkg/store/gorm/orm.go:118?[0m ?[31;1m ?[0m ?[33m[2020-06-16 10:35:02]?[0m ?[35m[info] replacing callback `gorm:query` from E:/go/goworkspace/src/jupiter-demo/vendor/github.com/douyu/jupiter/pkg/store/gorm/orm.go:118?[0m ?[31;1m ?
