i found this post. "Guice newbie question: creating N objects on-
demand"
this work. but this is a good aproach ?.
public class ServerTCP implements ServerInterface {
private final DispatchHandler.Factory handlerFactory;
@Inject ServerTCP(DispatchHandler.Factory handlerFactory) { ... }
@Override
public void start() {
try {
ServerSocket serverSocket = new ServerSocket(4000);
//<-- @Named
("port") int port ?.
while(true){
Socket socket = serverSocket.accept();
handlerFactory.newInstance(socket).start();
}
} catch (IOException e) { e.printStackTrace(); }
}
}
public class DispatchHandler extends Thread {
private Socket socket;
private DispatchHandler(Socket socket) {
this.socket = socket;
}
public static class Factory {
public DispatchHandler newInstance(Socket socket) {
return new DispatchHandler(socket);
}
}
public void run() { /*TODO...*/ }
}
