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 :

set GO111MODULE=on
set GOPROXY=https://mirrors.aliyun.com/goproxy/,direct

linux :

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

如何使用

  • jupiter -h
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
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
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
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:

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
cd cmd
go run main.go --config=../config/config.toml

接下来你将会看到以下日志

E:\go\goworkspace\src\jupiter-demo\cmd>go run main.go --config=../config/config.toml

模板项目中 我们默认帮你开启了HTTP,GRPC,JOB等服务。当然你也可以根据自己的需求进行取舍
接下来打开浏览器输入:
http://127.0.0.1:20105/jupiter
你将会看到 welcome to jupiter

在开始运行项目前我们不是配置过数据库环境么? 接下来我们可以验证查询是否正常:
打开浏览器输入: http://127.0.0.1:20105/api/user/1
你将会看到 {"id":1,"username":"admin","password":"123456","nickname":"rose","address":"WUHAN"}

如果以上操作你都正常完成，恭喜你，你已经完成了基础操作，接下来我们将介绍脚手架工具的 protoc模块

protoc 工具集介绍

jupiter protoc工具集目前可用于根据pb文件中的proto文件，生成pb.go，以及生成服务端实现， 你只需要去完善对应服务端实现的业务逻辑即可。

  • 环境准备 请确保当前系统安装protoc 编译工具
    go版本的 Protobuf 编译器插件,工具内部采用的是性能更好的 protoc-gen-gofast ,若检测到当前系统安装会自动进行安装
  • 实操演示
    脚手架中默认提供的 pb/hello/hello.proto 文件,以下操作都是基于该文件
    进入到项目根目录下，执行以下命令
  1. 生成pb.go 文件
 jupiter protoc -f ./pb/hello/hello.proto -o ./pb/hello -g

命令解释:
-f : proto文件路径
-o :生成文件目录(建议生成目录与proto文件同级，方便管理)
-g :是否生成pb.go 文件

正常情况下会在 ./pb/hello/中 生成 hello.pb.go 文件

  1. 生成grpc服务端实现
jupiter protoc -f ./pb/hello/hello.proto -o ./internal/app/grpc -p jupiter-demo -s

命令解释:
-f : proto文件路径
-o : grpc服务端代码生成文件目录(建议生成至./internal/app/grpc 中)
-p : grpc服务端代码实现依赖pb.go的前缀(请使用当前项目名)
-s : 是否生成grpc服务端实现代码

正常情况下会在 ./internal/app/grpc/hello 目录中 生成 helloServiceServer.go 文件
请注意: 我们在grpc包中会默认以proto的package的包名来管理 grpc服务端实现代码,从而让代码结构更加清晰
接下来 你只需要去该文件中完成对应的业务逻辑实现即可

快速测试grpc服务端代码:
框架内部我们支持 代理http到grpc控制器,并且在engine.go中我们也提供了相关的示例

	//support proxy for http to grpc controller
	g := greeter.Greeter{}
	group2 := server.Group("/grpc")
	group2.GET("/get", xecho.GRPCProxyWrapper(g.SayHello))
	group2.POST("/post", xecho.GRPCProxyWrapper(g.SayHello))

你可以参照该示例,将自己的grpc服务端实现注册在路由中，然后通过HTTP请求即可访问
