01.Play Framework 2.0

Play 2.0 是一個擁有高生產力(high-productivity)的 Java 和 Scala 混用的 Web 應用開發框架,它整合了現代需求的組件集和 API。

Play 框架強調自我是一個輕量級(lightweight),無狀態(stateless),且俱網路友善(web-friendly)的架構根基,有著特色預行(features predictable)和最小資源耗損 (CPU, memory, threads) 的高度可伸縮(highly-scalable)應用程序開發技術 -  - thanks to its reactive model, based on Iteratee IO. 。 

Play 2.0

Play 2.0 is a high productivity Java and Scala Web application framework, integrating all components and API needed for modern Web application development.

It is based on a lightweight stateless Web friendly architecture and features predictable and minimal resources consumption (CPU, Memory, Threads) for highly scalable applications thanks to its reactive model based on Iteratee IO.



For convenience, you should add the framework installation directory to your system PATH. On UNIX systems will be something like:

export PATH=$PATH:/path/to/play2.0

On windows systems you'll need to set it in the global environment variables.

If you’re on UNIX, make sure that the play script is executable (otherwise do a chmod a+x play).

Getting started

Enter any existing Play 2.0 application directory and use the play command to launch the development console:

$ cd ~/workspace/myApplication
$ play

You can also directly use play run to run the application:

$ cd ~/workspace/myApplication
$ play run

Use play new yourNewApplication to create a new application:

$ cd ~/workspace
$ play new myNewApplication

Once the application is created, use it as any existing application:

$ cd myNewApplication
$ play

Running the sample applications

There are several samples applications included in the samples/ directory. For example, to run the included Scala Hello World application:

$ cd ~/workspace/play2.0/samples/scala/helloworld/
$ play run

The application will be available on port 9000.
