Grails关注将"规约编程"(coding by convention)引入Groovy。它是一个开放源网络应用构架, 对Groovy语言起到杠杆作用,并且对Java网络开发起到补足作用。你可以用Grails 作为独立开发环境, 它隐藏了所有的配置细节,也可以将它同和入你的Java商务逻辑。
Grails关注与使开发最简化,而且Grails的解决方案来自于广泛的开发者,不只局限于Java社区。
Grails构建在开源技术如Spring、Hibernate和SiteMesh之上,提供了一个类似于Rails 的平台可以与Java平台无缝集成. Groovy是一种“动态”或指令语言。动态语言一般用来加速和简化程序撰写。与Python或Ruby等其他指令语言不同的是,用Groovy撰写的程序,可与Java虚拟器结合。
