scala webアプリ　実践1-準備

scala play

scala webアプリと言っても、広いので、
今回は「play」というフレームワークを使ってやってみたいと思います。

実行環境

対象バージョン：play-2.1.1
OS:mac lion
java:1.7

インストール

公式から、zipをダウンロードして解凍

play へ環境パスを通す
export PATH=$PATH:/Users/hoge_one/Documents/plat/play-2.1.1

mac 系は　「chmod a+x play 」とする必要あり

起動確認
play help
新規アプリ作成
play new myFirstApp
What is the application name? [myFirstApp]
> 

Which template do you want to use for this new application? 

  1             - Create a simple Scala application
  2             - Create a simple Java application

> 1
OK, application myFirstApp is created.

Have fun!

こんな感じで対話形式で作ってくれる。rubyぽい
