akka简单示例-1
刚刚开始接触akka，网上找了2个简单示例，并在公司运营机器上尝试，踩了一些坑，在此记录。
1. 本地hello world
[torstan@sparkb5-i ~/akka_example/hello_world]$ cat src/helloWorld.scala
package our.examples
import akka.actor.Actor
import akka.actor.ActorSystem
import akka.actor.Props class HelloActor extends Actor {
def receive = {
case "hello" => println("hello back at you")
case _ => println("huh?")
}
} object HelloApp extends App {
override def main(args: Array[String]){
val system = ActorSystem("HelloSystem")
// default Actor constructor
val helloActor = system.actorOf(Props[HelloActor], name = "helloactor")
helloActor ! "hello"
helloActor ! "buenos dias"
}
}
[torstan@sparkb5-i ~/akka_example/hello_world]$ cat Makefile
SRC_DIR := src
SRC := $(shell find ${SRC_DIR} -name "*.scala")
DIR=our TARGET := HelloApp.jar SCALAC := scalac
SCFLAGS := /usr/local/scala-2.10.4/lib/akka-actors.jar .PHONY: all clean all: ${TARGET} ${TARGET}: ${SRC}
${SCALAC} -cp ${SCFLAGS} $^ clean:
${RM} -r ${TARGET} ${DIR}
[torstan@sparkb5-i ~/akka_example/hello_world]$ cat run.sh
#!/bin/bash java -cp \
.:/usr/local/scala-2.10.4/lib/scala-library.jar:/usr/local/scala-2.10.4/lib/akka-actors.jar:/usr/local/scala-2.10.4/lib/typesafe-config.jar\
our.examples.HelloApp
执行结果：
[torstan@sparkb5-i ~/akka_example/hello_world]$ ./run.sh
hello back at you
huh?
2. 简单CS示例
server端：
[torstan@sparkb5-i ~/akka_example/remote_service/server]$ cat src/HelloRemote.scala
package remote
import akka.actor.Actor
import akka.actor.ActorSystem
import akka.actor.Props class RemoteActor extends Actor{
def receive = {
case msg:String =>
println(s"RemoteActor received message '$msg'")
sender ! "hello from RemoteActor"
}
} object HelloRemote extends App{
val system = ActorSystem("HelloRemoteSystem")
val remoteActor = system.actorOf(Props[RemoteActor], name="RemoteActor")
remoteActor ! "The remote actor is alive"
}
[torstan@sparkb5-i ~/akka_example/remote_service/server]$ cat application.conf
akka {
loglevel = "DEBUG"
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
//log-sent-messages = on
//log-received-messages = on
netty {
hostname = "172.27.6.240"
port = 5150
}
}
}
[torstan@sparkb5-i ~/akka_example/remote_service/server]$ cat Makefile
SRC_DIR := src
SRC := $(shell find ${SRC_DIR} -name "*.scala")
DIR=remote TARGET := HelloRemote.jar SCALAC := scalac
SCFLAGS := /usr/local/scala-2.10.4/lib/akka-actors.jar .PHONY: all clean all: ${TARGET} ${TARGET}: ${SRC}
${SCALAC} -cp ${SCFLAGS} $^ clean:
${RM} -r ${TARGET} ${DIR}
[torstan@sparkb5-i ~/akka_example/remote_service/server]$ cat run.sh
#!/bin/bash AKKA_LIB_PATH="/usr/local/akka-2.1.4/lib/akka/" java -cp \

remote.HelloRemote
client端：
[torstan@sparkb5-i ~/akka_example/remote_service/client]$ cat src/HelloLocal.scala
package client
import akka.actor._ object HelloLocal extends App{
implicit val system = ActorSystem("LocalSystem")
val localActor = system.actorOf(Props[LocalActor], name="LocalActor")
localActor ! "START"
} class LocalActor extends Actor{
val remote = context.actorFor("akka://HelloRemoteSystem@172.27.6.240:5150/user/RemoteActor")
var counter = 0
def receive = {
case "START" =>
remote ! "HELLO from the LocalActor"
case msg:String =>
println(s"LocalActor received message: '$msg'")
if(counter < 5){
sender ! "hello back to you"
counter += 1
}
}
}
[torstan@sparkb5-i ~/akka_example/remote_service/client]$ cat application.conf
akka {
//loglevel = "DEBUG"
actor {
provider = "akka.remote.RemoteActorRefProvider"
}
remote {
transport = "akka.remote.netty.NettyRemoteTransport"
//log-sent-messages = on
//log-received-messages = on
netty {
hostname = "127.0.0.1"
port = 0
}
}
}
[torstan@sparkb5-i ~/akka_example/remote_service/client]$ cat Makefile
SRC_DIR := src
SRC := $(shell find ${SRC_DIR} -name "*.scala")
DIR=client TARGET := HelloLocal.jar SCALAC := scalac
SCFLAGS := /usr/local/scala-2.10.4/lib/akka-actors.jar .PHONY: all clean all: ${TARGET} ${TARGET}: ${SRC}
${SCALAC} -cp ${SCFLAGS} $^ clean:

遇到的坑：

google到答案是没有加载依赖文件akka-remote.jar，后来发现是没有安装akka。
2. Exception in thread "main" java.lang.NoSuchMethodException: akka.remote.RemoteActorRefProvider.<init>(java.lang.String, akka.actor.ActorSystem$Settings, akka.event.EventStream, akka.actor.Scheduler, akka.actor.DynamicAccess
