Play Version:2.3.1

The Play team is pleased to announce the release of Play 2.3.0!

What’s new inPlay2.3

1. Introducing the activator command. You can useactivator exactly like you would use play, but Activator brings new features too. (More about the Activator change.)

2. Better tooling for static assets.Play now uses sbt-web which gives faster asset processing, more features, and better extensibility.

3. Support forJava 8 (and continued support for Java 6 and 7).

4. BetterJava performance. Simple Java controllers give 40–90% better throughput. (Thanks toYourKit for sponsoring licenses.)

5. Support forScala 2.11 (and continued support for Scala 2.10).

6. Anorm enhancements: SQL string interpolation, multi-value parameters, new types, and more.

7. Web Services enhancements: separate client, SSL configuration, and more.

8. Play templates have become Twirl templates: separate project, new sbt plugin, still excellent integration withPlay

9. Actors for WebSockets

10. Custom SSLEngine for HTTPS

11. Asset performance: faster serving, better caching.

12. One Result to rule them all: all the result types which were deprecated in 2.2 are now gone and only Result remains.

13. Lots of bug fixes. :)

For details see the Play2.3 Highlights and thePlay2.3 Migration Guide.

installing

下载完整的zip文件，而不是min。

 There are three ways to run activator:


 1. Recommended: try `activator ui` to create a project in the UI
 2. Use `activator new` to create a project on the command line
 3. Load an existing project by re-running activator in a project directory

activator ui

[error] p.nettyException - Exception caught in Netty
java.lang.IllegalArgumentException: invalid version format

http://stackoverflow.com/questions/21667254/play-framework-2-2-1-https-fails-on-connection-attempt

keytool -genkey -alias MyKey -keyalg RSA -keysize 2048 -keystore keystore.jks
play -Dhttps.port=9443 -Dhttps.keyStore=keystore.jks -Dhttps.keyStorePassword=password run

上面说使用这个命令就解决了问题。

我试过了

activator new my-first-app play-java

提示说找不到template，因为无法去访问某个地址。

于是设置了~/.activator/activatorconfig.txt

<span ><span ># This are the proxy settings we use for activator
-Dhttp.proxyHost=localhost
-Dhttp.proxyPort=8580
# Here we configure the hosts which should not go through the proxy.  You should include your private network, if applicable.
-Dhttp.nonProxyHosts="localhost|127.0.0.1|davidzhang-pc|192.168.0.104"</span></span>

cd my-first-app

activator

$run

出错

org.jboss.netty.channel.ChannelException: Failed to bind to: /0.0.0.0:9000

stackflow里面提到了解决方法，不能使用9000端口！

$run 9001

<span ><span >[my-first-app] $ run 9001

--- (Running the application from SBT, auto-reloading is enabled) --

使用IDE调试debug play app:

step1:activator your application with a debug port

activator -jvm-debug 9999 

step2:add a debug configuration in IDE

and in Eclipse right-click on the project and select Debug As, Debug Configurations. In the Debug Configurations dialog, right-click on Remote Java Application and select New. Change Port to 9999 and click Apply. From now on you can click on Debug to connect to the running application. Stopping the debugging session will not stop the server.

step3:run app listending a port

run  9001

step4:add breakpoints in play project app sourcecode

step5:input a url in a browser, test your web app:

http://localhost:9001

Scala + Play + Sbt + Protractor = One Build

一位朋友分享的项目

https://github.com/smeite/smeite

食美特的项目地址在 https://github.com/smeite/smeite  已经有好几个月没有更新了，感兴趣的朋友可以去玩玩。整个网站采用playframework2.1+slick+mysql做的架构，有 52个 数据表，前端js使用的是seajs 2.1 和淘宝前端aralejs javascript框架。网站的访问速度和压力都非常不错，做了很多优化，更兴趣的朋友可以去github上看看。
