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 gitee.com/nonull/eden/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

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:
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
- 请先在mysql中创建test库,然后将sql中的user.sql在该库中执行
- 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

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
- 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
- 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
