3 つのコンポーネントで構成されるシステムでパス コントロールをシミュレートする簡単なプログラムを書くことができました。しかし、ログが期待していたように見えないため、正しく行ったかどうかはわかりません。
間違いが見つかりませんでした。それは、aspectJ-part または RMI-part にありますか?
RMIサーバー
public class RMIServer {
public static void main(String[] args) throws RemoteException,
MalformedURLException {
LocateRegistry.createRegistry(1099);
HelloIF hello = new Hello();
Naming.rebind("server.Hello", hello);
System.out.println("Server is ready.");
}
}
RMIServer2
public class RMIServer2 {
public static void main(String[] args) throws RemoteException,
MalformedURLException, NotBoundException, InterruptedException {
//LocateRegistry.createRegistry(1098);
LocateRegistry.getRegistry(1099);
ByeIF bye = new Bye();
Naming.rebind("server.Bye", bye);
System.out.println("Server-Client is ready.");
}
RMIClient
public class RMIClient {
public static void main(String[] args) throws RemoteException,
MalformedURLException, NotBoundException, InterruptedException {
Registry registry = LocateRegistry.getRegistry("localhost");
ByeIF bye = (ByeIF) registry.lookup("server.Bye");
System.out.println(bye.farewell(Thread.currentThread().getName()));
}
}
こんにちは
public class Hello extends UnicastRemoteObject implements HelloIF {
public Hello() throws RemoteException {
}
public String greeting(String c) throws RemoteException,
InterruptedException {
return "Good morning!";
}
}
さよなら
public class Bye extends UnicastRemoteObject implements ByeIF {
public Bye() throws RemoteException {
}
public String farewell(String c) throws RemoteException,
InterruptedException, NotBoundException {
Registry registry = LocateRegistry.getRegistry("localhost");
HelloIF hello = (HelloIF) registry.lookup("server.Hello");
System.out.println(hello.greeting(Thread.currentThread().getName()));
return "Bye bye!";
}
}
ログは次のようになります。
[2012-08-03 11:06:18,582] [request1343984778582] [public static void hello.RMIClient.main(java.lang.String[])]

そのため、1 つのログが欠落しています -Bye.farewell()
メソッドがいつ終了するかをaspectJが認識できない理由がわかりません。
