java Play框架入门 ( simple tutorial for play framework)

注意：：： 官方的文档不给力啊，按照他说的做，会遇到各种问题。文档更新的速度没跟上代码。。。最好的办法是运行：  sample 目录下的 项目。    ( CAUTION:  official tutorial is not correct from my experience today, the best way is to run the sample applications in the "sample" folder , check it out! )

1. 下载并解压缩最新的文件。( Download and unzip the play framework file ) :

2. 为 "play" 这个文件加上可执行的标志 : chmod +x play ,并把它放到系统PATH中。 ( make the 'play' file executable and add its path to PATH )

3. 建立一个空的应用 ： ( create an empty play application)
$ play new test_play_framework 

4. 打开控制台：  (open its console)
$ cd test_play_framework
$ run

sg552@siwei-moto:~/workspace/test_play$ play

[test_play] $ run

[info] Done updating.                                                                  
--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on port 9000...

(Server started, use Ctrl+D to stop and go back to the console...)

可以看到服务器运行在了9000端口，打开。。。( we could see that the server is running at: localhost:9000, open it )
