public void startServers() throws Exception {
        for (ServerFace face : getBeans(ServerFace.class)) {
            serverFaces.add(face);
            face.start();
        }
    }
public void startServers ( ) throws Exception { for ( ServerFace face : getBeans ( ServerFace . class ) ) { serverFaces . add ( face ) ; face . start ( ) ; } }
循环调用ServerFace的start方法,通常是一个starter
