bee 工具是一個為了協(xié)助快速開發(fā) beego 項目而創(chuàng)建的項目,通過 bee 您可以很容易的進行 beego 項目的創(chuàng)建、熱編譯、開發(fā)、測試、和部署。
您可以通過如下的方式安裝 bee 工具:
go get github.com/beego/bee
安裝完之后,bee 可執(zhí)行文件默認存放在 $GOPATH/bin 里面,所以您需要把 $GOPATH/bin 添加到您的環(huán)境變量中,才可以進行下一步。
如何添加環(huán)境變量,請自行搜索 如果你本機設(shè)置了 GOBIN,那么上面的命令就會安裝到 GOBIN 下,請?zhí)砑?GOBIN 到你的環(huán)境變量中
我們在命令行輸入 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
new Creates a Beego application
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 命令是新建一個 Web 項目,我們在命令行下執(zhí)行 bee new <項目名> 就可以創(chuàng)建一個新的項目。但是注意該命令必須在 $GOPATH/src 下執(zhí)行。最后會在 $GOPATH/src 相應目錄下生成如下目錄結(jié)構(gòu)的項目:
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/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

上面的 new 命令是用來新建 Web 項目,不過很多用戶使用 beego 來開發(fā) API 應用。所以這個 api 命令就是用來創(chuàng)建 API 應用的,執(zhí)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
這個項目的目錄結(jié)構(gòu)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
從上面的目錄我們可以看到和 Web 項目相比,少了 static 和 views 目錄,多了一個 test 模塊,用來做單元測試的。
同時,該命令還支持一些自定義參數(shù)自動連接數(shù)據(jù)庫創(chuàng)建相關(guān) model 和 controller: bee api [appname] [-tables=""] [-driver=mysql] [-conn="root:<password>@tcp(127.0.0.1:3306)/test"] 如果 conn 參數(shù)為空則創(chuàng)建一個示例項目,否則將基于鏈接信息鏈接數(shù)據(jù)庫創(chuàng)建項目。
我們在開發(fā) Go 項目的時候最大的問題是經(jīng)常需要自己手動去編譯再運行,bee run 命令是監(jiān)控 beego 的項目,通過 fsnotify監(jiān)控文件系統(tǒng)。但是注意該命令必須在 $GOPATH/src/appname 下執(zhí)行。 這樣我們在開發(fā)過程中就可以實時的看到項目修改之后的效果:
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 09:53:16 [INFO] ./myproject is running...
我們打開瀏覽器就可以看到效果 http://localhost:8080/:
如果我們修改了 Controller 下面的 default.go 文件,我們就可以看到命令行輸出:
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 10:11:23 [INFO] Restarting myproject ...
13-11-25 10:11:23 [INFO] ./myproject is running...
刷新瀏覽器我們看到新的修改內(nèi)容已經(jīng)輸出。
pack 目錄用來發(fā)布應用的時候打包,會把項目打包成 zip 包,這樣我們部署的時候直接把打包之后的項目上傳,解壓就可以部署了:
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`
我們可以看到目錄下有如下的壓縮文件:
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
這個命令目前僅限內(nèi)部使用,具體實現(xiàn)方案未完善,主要用來壓縮所有的靜態(tài)文件變成一個變量申明文件,全部編譯到二進制文件里面,用戶發(fā)布的時候攜帶靜態(tài)文件,包括 js、css、img 和 views。最后在啟動運行時進行非覆蓋式的自解壓。
這個命令是動態(tài)獲取 bee、beego 和 Go 的版本,這樣一旦用戶出現(xiàn)錯誤,可以通過該命令來查看當前的版本
$ bee version
bee :1.2.2
beego :1.4.2
Go :go version go1.3.3 darwin/amd64
這個命令是用來自動化的生成代碼的,包含了從數(shù)據(jù)庫一鍵生成 model,還包含了 scaffold 的,通過這個命令,讓大家開發(fā)代碼不再慢
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
default for postgres: postgres://postgres:postgres@127.0.0.1:5432/postgres
-level: [1 | 2 | 3], 1 = models; 2 = models,controllers; 3 = models,controllers,router
這個命令是應用的數(shù)據(jù)庫遷移命令,主要是用來每次應用升級,降級的SQL管理。
bee migrate [-driver=mysql] [-conn="root:@tcp(127.0.0.1:3306)/test"]
run all outstanding migrations
-driver: [mysql | postgresql | sqlite], the default is mysql
-conn: the connection string used by the driver, the default is root:@tcp(127.0.0.1:3306)/test
bee migrate rollback [-driver=mysql] [-conn="root:@tcp(127.0.0.1:3306)/test"]
rollback the last migration operation
-driver: [mysql | postgresql | sqlite], the default is mysql
-conn: the connection string used by the driver, the default is root:@tcp(127.0.0.1:3306)/test
bee migrate reset [-driver=mysql] [-conn="root:@tcp(127.0.0.1:3306)/test"]
rollback all migrations
-driver: [mysql | postgresql | sqlite], the default is mysql
-conn: the connection string used by the driver, the default is root:@tcp(127.0.0.1:3306)/test
bee migrate refresh [-driver=mysql] [-conn="root:@tcp(127.0.0.1:3306)/test"]
rollback all migrations and run them all again
-driver: [mysql | postgresql | sqlite], the default is mysql
-conn: the connection string used by the driver, the default is root:@tcp(127.0.0.1:3306)/test
這個命令可以通過生成Dockerfile文件來實現(xiàn)docker化你的應用。
例子:生成一個以1.6.4版本Go環(huán)境為基礎(chǔ)鏡像的Dockerfile,并暴露9000端口:
$ bee dockerize -image="library/golang:1.6.4" -expose=9000

您可能已經(jīng)注意到,在 bee 工具的源碼目錄下有一個 bee.json 文件,這個文件是針對 bee 工具的一些行為進行配置。該功能還未完全開發(fā)完成,不過其中的一些選項已經(jīng)可以使用:
