bee 工具简介
bee 工具是一个为了协助快速开发 beego 项目而创建的项目,通过 bee 您可以很容易的进行 beego 项目的创建、热编译、开发、测试、和部署。
bee 工具的安装
您可以通过如下的方式安装 bee 工具:
go get github.com/beego/bee
安装完之后,bee
可执行文件默认存放在 $GOPATH/bin
里面,所以您需要把 $GOPATH/bin
添加到您的环境变量中,才可以进行下一步。
如何添加环境变量,请自行搜索
如果你本机设置了GOBIN
,那么上面的命令就会安装到GOBIN
下,请添加 GOBIN 到你的环境变量中
bee 工具命令详解
我们在命令行输入 bee
,可以看到如下的信息:
Bee is a Fast and Flexible tool for managing your Beego Web Application.
Usage:
bee command [arguments]
The commands are:
version show the bee & beego version
migrate run database migrations
api create an api application base on beego framework
bale packs non-Go files to Go source files
new create an application base on beego framework
run run the app which can hot compile
pack compress an beego project
fix Fixes your application by making it compatible with newer versions of Beego
dlv Start a debugging session using Delve
dockerize Generates a Dockerfile for your Beego application
generate Source code generator
hprose Creates an RPC application based on Hprose and Beego frameworks
pack Compresses a Beego application into a single file
rs Run customized scripts
run Run the application by starting a local development server
server serving static content over HTTP on port
Use bee help [command] for more information about a command.
new
命令
new
命令是新建一个 Web 项目,我们在命令行下执行 bee new <项目名>
就可以创建一个新的项目。但是注意该命令必须在 $GOPATH/src
下执行。最后会在 $GOPATH/src
相应目录下生成如下目录结构的项目:
bee new myproject
[INFO] Creating application...
/gopath/src/myproject/
/gopath/src/myproject/conf/
/gopath/src/myproject/controllers/
/gopath/src/myproject/models/
/gopath/src/myproject/static/
/gopath/src/myproject/static/js/
/gopath/src/myproject/static/css/
/gopath/src/myproject/static/img/
/gopath/src/myproject/views/
/gopath/src/myproject/conf/app.conf
/gopath/src/myproject/controllers/default.go
/gopath/src/myproject/views/index.tpl
/gopath/src/myproject/main.go

api
命令
上面的 new
命令是用来新建 Web 项目,不过很多用户使用 beego 来开发 API 应用。所以这个 api
命令就是用来创建 API 应用的,执行命令之后如下所示:
bee api apiproject
create app folder: /gopath/src/apiproject
create conf: /gopath/src/apiproject/conf
create controllers: /gopath/src/apiproject/controllers
create models: /gopath/src/apiproject/models
create tests: /gopath/src/apiproject/tests
create conf app.conf: /gopath/src/apiproject/conf/app.conf
create controllers default.go: /gopath/src/apiproject/controllers/default.go
create tests default.go: /gopath/src/apiproject/tests/default_test.go
create models object.go: /gopath/src/apiproject/models/object.go
create main.go: /gopath/src/apiproject/main.go
这个项目的目录结构如下:
apiproject
├── conf
│ └── app.conf
├── controllers
│ └── object.go
│ └── user.go
├── docs
│ └── doc.go
├── main.go
├── models
│ └── object.go
│ └── user.go
├── routers
│ └── router.go
└── tests
└── default_test.go
从上面的目录我们可以看到和 Web 项目相比,少了 static 和 views 目录,多了一个 test 模块,用来做单元测试的。
同时,该命令还支持一些自定义参数自动连接数据库创建相关 model 和 controller:bee api [appname] [-tables=""] [-driver=mysql] [-conn="root:<password>@tcp(127.0.0.1:3306)/test"]
如果 conn 参数为空则创建一个示例项目,否则将基于链接信息链接数据库创建项目。
run
命令
我们在开发 Go 项目的时候最大的问题是经常需要自己手动去编译再运行,bee run
命令是监控 beego 的项目,通过 fsnotify监控文件系统。但是注意该命令必须在 $GOPATH/src/appname
下执行。
这样我们在开发过程中就可以实时的看到项目修改之后的效果:
bee run
13-11-25 09:53:04 [INFO] Uses 'myproject' as 'appname'
13-11-25 09:53:04 [INFO] Initializing watcher...
13-11-25 09:53:04 [TRAC] Directory(/gopath/src/myproject/controllers)
13-11-25 09:53:04 [TRAC] Directory(/gopath/src/myproject/models)
13-11-25 09:53:04 [TRAC] Directory(/gopath/src/myproject)
13-11-25 09:53:04 [INFO] Start building...

13-11-25 09:53:16 [INFO] Restarting myproject ...
13-11-25 09:53:16 [INFO] ./myproject is running...
我们打开浏览器就可以看到效果 http://localhost:8080/
:
如果我们修改了 Controller
下面的 default.go
文件,我们就可以看到命令行输出:
13-11-25 10:11:20 [EVEN] "/gopath/src/myproject/controllers/default.go": DELETE|MODIFY
13-11-25 10:11:20 [INFO] Start building...
13-11-25 10:11:20 [SKIP] "/gopath/src/myproject/controllers/default.go": CREATE
13-11-25 10:11:23 [SKIP] "/gopath/src/myproject/controllers/default.go": MODIFY
13-11-25 10:11:23 [SUCC] Build was successful
13-11-25 10:11:23 [INFO] Restarting myproject ...
13-11-25 10:11:23 [INFO] ./myproject is running...
刷新浏览器我们看到新的修改内容已经输出。
pack
命令
pack
目录用来发布应用的时候打包,会把项目打包成 zip 包,这样我们部署的时候直接把打包之后的项目上传,解压就可以部署了:
bee pack
app path: /gopath/src/apiproject
GOOS darwin GOARCH amd64
build apiproject
build success
exclude prefix:
exclude suffix: .go:.DS_Store:.tmp
file write to `/gopath/src/apiproject/apiproject.tar.gz`
我们可以看到目录下有如下的压缩文件:
rwxr-xr-x 1 astaxie staff 8995376 11 25 22:46 apiproject
-rw-r--r-- 1 astaxie staff 2240288 11 25 22:58 apiproject.tar.gz
drwxr-xr-x 3 astaxie staff 102 11 25 22:31 conf
drwxr-xr-x 3 astaxie staff 102 11 25 22:31 controllers
-rw-r--r-- 1 astaxie staff 509 11 25 22:31 main.go
drwxr-xr-x 3 astaxie staff 102 11 25 22:31 models
drwxr-xr-x 3 astaxie staff 102 11 25 22:31 tests
bale
命令
这个命令目前仅限内部使用,具体实现方案未完善,主要用来压缩所有的静态文件变成一个变量申明文件,全部编译到二进制文件里面,用户发布的时候携带静态文件,包括 js、css、img 和 views。最后在启动运行时进行非覆盖式的自解压。
version
命令
这个命令是动态获取 bee、beego 和 Go 的版本,这样一旦用户出现错误,可以通过该命令来查看当前的版本
$ bee version
bee :1.2.2
beego :1.4.2
Go :go version go1.3.3 darwin/amd64
generate
命令
这个命令是用来自动化的生成代码的,包含了从数据库一键生成 model,还包含了 scaffold 的,通过这个命令,让大家开发代码不再慢
bee generate scaffold [scaffoldname] [-fields=""] [-driver=mysql] [-conn="root:@tcp(127.0.0.1:3306)/test"]
The generate scaffold command will do a number of things for you.
-fields: a list of table fields. Format: field:type, ...
-driver: [mysql | postgres | sqlite], the default is mysql
-conn: the connection string used by the driver, the default is root:@tcp(127.0.0.1:3306)/test
example: bee generate scaffold post -fields="title:string,body:text"
bee generate model [modelname] [-fields=""]
generate RESTful model based on fields
-fields: a list of table fields. Format: field:type, ...
bee generate controller [controllerfile]
generate RESTful controllers
bee generate view [viewpath]
generate CRUD view in viewpath
bee generate migration [migrationfile] [-fields=""]
generate migration file for making database schema update
-fields: a list of table fields. Format: field:type, ...
bee generate docs
generate swagger doc file
bee generate test [routerfile]
generate testcase
bee generate appcode [-tables=""] [-driver=mysql] [-conn="root:@tcp(127.0.0.1:3306)/test"] [-level=3]
generate appcode based on an existing database
-tables: a list of table names separated by ',', default is empty, indicating all tables
-driver: [mysql | postgres | sqlite], the default is mysql
-conn: the connection string used by the driver.
default for mysql: root:@tcp(127.0.0.1:3306)/test
