java actor模型和消息传递简单示例

接上面java actor模型框架ujavaactor http://zhwj184.iteye.com/admin/blogs/1613351，上面的示例比较复杂，写一个简单点的示例：

import java.util.HashMap;import java.util.Map;import com.ibm.actor.AbstractActor;import com.ibm.actor.Actor;import com.ibm.actor.DefaultActorManager;import com.ibm.actor.DefaultMessage;import com.ibm.actor.Message;public class TestActor extends AbstractActor {private Actor to;public void setTestActor(Actor sendTo) {this.to = sendTo;}@Overridepublic void activate() {super.activate();}@Overridepublic void deactivate() {logger.trace("TestActor deactivate: %s", getName());super.deactivate();}@Overrideprotected void runBody() {DefaultMessage m = new DefaultMessage("message->from :" + getName(), 20);getManager().send(m, null, this);}@Overrideprotected void loopBody(Message m) {String subject = m.getSubject();int count = (Integer) m.getData();if (count > 0) {m = new DefaultMessage("message->from :" + getName(), count - 1);System.out.println(getName() + ":" + subject + " data:" + m.getData());getManager().send(m, this, to);}}public static void main(String[] args) {DefaultActorManager am = new DefaultActorManager();Map<String, Actor> actors = new HashMap<String, Actor>();try {Map<String, Object> options = new HashMap<String, Object>();options.put(DefaultActorManager.ACTOR_THREAD_COUNT, 2);am.initialize(options);TestActor a = (TestActor) am.createActor(TestActor.class, "actor0");actors.put(a.getName(), a);TestActor b = (TestActor) am.createActor(TestActor.class, "actor1");actors.put(b.getName(), b);a.setTestActor(b);b.setTestActor(a);for (String key : actors.keySet()) {am.startActor(actors.get(key));}Thread.sleep(10000000);// am.terminateAndWait();} catch (Exception e) {}}}

 输出：
