akka-cookbook

Book Akka Cookbook ⬆

Directory akka-cookbook\ contains Akka examples presented in Ortiz's book Akka Cookbook (Packt, 2017). It also includes different build scripts for experimenting with Akka on a Windows machine.

Code examples can be built/run with the following tools:

Build tool	Build file	Parent file	Environment(s)
ant.bat	build.xml	build.xml	Any a)
gradle.bat	build.gradle	common.gradle	Any
make.exe	Makefile	Makefile.inc	Any
mvn.cmd	pom.xml	pom.xml	Any
sbt.bat	build.sbt		Any
cmd.exe	build.bat		Windows only

^a) Here "Any" means "tested on Windows, Cygwin, MSYS2 and UNIX".

HelloAkka Example

The project directory is organised as follows :

> tree /a /f . | findstr /v /b [A-Z]
|   build.bat
|   build.gradle
|   build.sbt
|   build.sh
|   build.xml
|   gradle.properties
|   Makefile
|   pom.xml
+---project
|       build.properties
\---src
    +---main
    |   +---resources
    |   |       application.conf
    |   |       logback.xml
    |   \---scala
    |           HelloAkka.scala
    \---test
        +---java
        |       HelloAkkaTestJava.java
        \---scala
                HelloAkkaTest.scala

Batch file build.bat matches what a user would run from the command prompt (use option -debug to see the execution details):

> build -verbose run
Compile 1 Scala source file to directory "target\classes"
[HelloAkka-akka.actor.default-dispatcher-4] INFO akka.event.slf4j.Slf4jLogger - Slf4jLogger started
akka://HelloAkka
>>> Press ENTER to exit <<<

🔎 Commands ant.bat (build.xml), gradle.bat (build.gradle), make (Makefile), mvn (pom.xml) and sbt (build.sbt) produce the same output; for instance :

> make -s run
akka://HelloAkka
>>> Press ENTER to exit <<<

BehaviourAndState Example ▴

Batch file build.bat matches what a user would run from the command prompt (use option -debug to see the execution details):

> build -verbose run
Compile 2 Scala source files to directory "target\classes"
[BehaviourAndState-akka.actor.default-dispatcher-5] INFO akka.event.slf4j.Slf4jLogger - Slf4jLogger started
actor.path=akka://BehaviourAndState/user/summingActor
my state as sum is 2
>>> Press ENTER to exit <<<

[BehaviourAndState-akka.actor.default-dispatcher-5] INFO akka.actor.CoordinatedShutdown - Running CoordinatedShutdown with reason [ActorSystemTerminateReason]
