win10+go+beego搭建用户管理系统

经过两天的从零开始研究学习，go程序的用户crud系统终于搭建成功，很不错吆。

go环境搭建

下载go1.9rc2.windows-amd64.msi,由于golang被墙，只能从其他网上下载。

采用默认安装到C:\Go，打开命令行，输入go version
C:\Users\steve>go version
go version go1.9rc2 windows/amd64

创建C:\GOPATH文件夹，添加环境变量

go开发工具安装配置

下载eclipse-inst-win64.exe（4.6.3）并安装
安装goclipse插件

因为GFC的封闭，我们需要先到https://github.com/GoClipse/goclipse.github.io/archive/master.zip下载GoClipse的安装包，并解压。然后打开Eclipse（确保已经包含CDT），Help -> Install New Software…，然后选择Add按钮，输入解压后的Release目录，选择GoClipse，然后一直next就安装成功了。安装完成后需要重启Eclipse。

勾选goclipse,下一步直至完成
打开：Window>Preferences

下载gocode.exe,guru.exe,godef.exe也可以不配置

Beego安装

下载并安装好Git bash工具

打开gitbash，输入 go get github.com/astaxie/beego 。稍等片刻即可在GOPATH的src目录下看到有\github.com\astaxie\beego目录。

在gitbash中输入 go get github.com/beego/bee 。稍等片刻即可在GOPATH的src目录下看到有\github.com\beego\bee目录，同时有很多依赖包被下载添加到\github.com目录下。

新建项目

cd %GOPATH%/src
bee new hello
cd hello
bee run hello
在浏览器输入127.0.0.1:8080就看到了运行结果（welcome to beego的欢迎页）

goeclipse开发

打开eclipse，导入hello项目

新建文件，结构如下

app.conf

appname = hello
httpport = 8080
runmode = dev

db.host = localhost
db.port = 3306
db.user = root
db.pass = 123456
db.name = test
db.timezone = Asia/Shanghai

c.ServeJSON()

命令行启动bee

（以后可以直接启动hello.exe）
