grizzly http 服务器应该继续运行

Question

下面是启动 Grizzly Http Server 的代码。如果我按任何键，服务器就会停止。有什么办法让它活着。

Jetty 有 join() 方法，不会退出主程序。灰熊中是否也有类似的东西。

public static void main(String args){



ResourceConfig rc = new PackagesResourceConfig("com.test.resources");

        HttpServer httpServer = GrizzlyServerFactory.createHttpServer(BASE_URI, rc);
        logger.info(String.format("Jersey app started with WADL available at "
                        + "%sapplication.wadl\nTry out %shelloworld\nHit enter to stop it...",
                        BASE_URI, BASE_URI));

        System.in.read();
        httpServer.stop();

        }

根据上面的代码，如果您按下任何键，服务器就会停止。我想让它继续运行。当我真正想停止服务器时，我会终止该进程。 main 方法不应终止。

谢谢

我使用关机钩子(Hook)。这是一个代码示例:

public class ExampleServer {
private static final Logger logger = LoggerFactory
        .getLogger(ExampleServer.class);

public static void main(String[] args) throws IOException {
    new Server().doMain(args);
}

public void doMain(String[] args) throws IOException {
    logger.info("Initiliazing Grizzly server..");
    // set REST services packages
    ResourceConfig resourceConfig = new PackagesResourceConfig(
            "pt.lighthouselabs.services");

    // instantiate server
    final HttpServer server = GrizzlyServerFactory.createHttpServer(
            "http://localhost:8080", resourceConfig);

    // register shutdown hook
    Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
        @Override
        public void run() {
            logger.info("Stopping server..");
            server.stop();
        }
    }, "shutdownHook"));

    // run
    try {
        server.start();
        logger.info("Press CTRL^C to exit..");
        Thread.currentThread().join();
    } catch (Exception e) {
        logger.error(
                "There was an error while starting Grizzly HTTP server.", e);
    }
}

}
