Groovy轻松入门——Grails实战基础篇(1)

在学习任何东西之前，最重要的是培养兴趣，Groovy世界最耀眼的技术之一－－Grails相信大家早已耳闻，我将通过Grails实战系列文章向您展现Grails的迷人风采，使您感受到Grails的魅力，以至疯狂地爱上Grails，并坠入Groovy的爱河。学Groovy，Grails与学Java一样，在实战之前需要搭建开发环境，您可以在 Groovy轻松入门－－搭建Groovy开发环境 学习到如何搭建Groovy环境，之后我会讲一下如何搭建Grails环境，然后手把手地写个Demo程序告终，我还会抽空写篇“Groovy轻松入门－－Grails实战之进阶篇”

一，搭建Grails环境

0，下载Grails( http://dist.codehaus.org/grails/grails-bin-0.4.2.zip ，请留意朝花夕拾——Groovy & Grails中的“最新版本”提示)并解压到自己指定位置（我的位置是D:/D/MY_DEV/grails）

1，设置环境变量GRAILS_HOME（注意大写），过程与“设置环境变量GROOVY_HOME”相似。

2，将%GRAILS_HOME%/bin添加到环境变量path中，过程与“将GROOVY_HOME目录下的bin追加到环境变量path中”相似。

（如果只想进行Grails开发，可以不设GROOVY_HOME）

二，创建Grails Demo程序

0，打开“命令行”，选择当前目录（我的为D:/Temp/grails_apps），在黑底白字的窗口中输入“grails create-app demo”，不包括双引号“”，在您的屏幕中可以看到类似下面的输出结果：
