Playframework(15)Update the Version to 2.3.8 Going with Java

 

Download the latest version, unzip that and do what ever I do in the past

If I create one new project based on scala

> activator new easyplay play-scala

 

To run "easyplay" from the command line, "cd easyplay" then:
/Users/carl/work/play/easyplay/activator run

To run the test for "easyplay" from the command line, "cd easyplay" then:
/Users/carl/work/play/easyplay/activator test

To run the Activator UI for "easyplay" from the command line, "cd easyplay" then:

/Users/carl/work/play/easyplay/activator ui

 

Check the Installation

> activator -help

 

try java project

> activator new easyplayjava play-java

 

It seems that there is some changes based on the new version. I will try to read the doc again.

Check Java Version

> java -version

java version "1.8.0_25"

 

> javac -version

javac 1.8.0_25

 

Activator Tool

It provides SBT and many templates.

Check the installation

> activator -help

 

Command to start the activator

> activator ui -Dhttp.address=0.0.0.0 -Dhttp.port=8888

 

Create a new Java Project

> activator new easyplayjava play-java

all the things are based on sbt. I am familiar with that.

 

This command will enter the console

> activator

 

activator, sbt, similar.

Asynchronous

https://www.playframework.com/documentation/2.3.x/JavaAsync

avoid blocking operation in controller, such as JDBC calls, steaming API, long computation.

 

Promise for client, another Promise to get the result.

 

promise() helper

Promise.promise(()->intensiveComputation());

Use thread to handle that.

https://www.playframework.com/documentation/2.3.x/ThreadPools

 

Java AKKA

https://www.playframework.com/documentation/2.3.x/JavaAkka

Play contains a default AKKA system.

 

Have AKKA system in controller, convert Future to Promise to return.
