1、groovy简介

其官方介绍为,Groovy...

is an agile and dynamic language（动态语言）or the Java Virtual Machine
builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk
makes modern programming features available to Java developers with almost-zero learning curve
provides the ability to statically type check and statically compile your code for robustness and performance
supports Domain-Specific Languages and other compact syntax so your code becomes easy to read and maintain
makes writing shell and build scripts easy with its powerful processing primitives, OO abilities and an Ant DSL
increases developer productivity by reducing scaffolding code when developing web, GUI, database or console applications
simplifies testing by supporting unit testing and mocking out-of-the-box
seamlessly integrates with all existing Java classes and libraries
compiles straight to Java bytecode so you can use it anywhere you can use Java

简单说来：Groovy是一种运行在JVM上的动态语言，它吸取了Python,Ruby和Smalltalk等语言的优点，在Java语言的基础之上增加了许多特色功能；对于Java开发人员来说掌握Groovy是没有什么太大障碍的；相比 Java 而言，语法更易懂，更易上手，更易调试；无缝的集成了Java 的类和库；编译后的.groovy也是以class的形式出现的。

语法是相当的松散
