我对 RestEasy 和 Netty 完全陌生。我只想运行一个非常简单的测试来看看 netty 是如何工作的。所以我正在使用这段代码：

ResteasyDeployment deployment = new ResteasyDeployment();
deployment.setResourceClasses(Collections.singletonList(OAIProviderImpl.class.getName()));


        NettyJaxrsServer netty = new NettyJaxrsServer();
        netty.setDeployment(deployment);
        netty.setPort(TestPortProvider.getPort());
        netty.setRootResourcePath("");
        netty.setSecurityDomain(null);
        netty.start();

        Thread.sleep(1000);

        netty.stop();

在一个Main()方法中。OAIProviderImpl.class只是一个实现 REST 接口的类。当我运行这段代码时。我NullpointerException打开netty.stop()并进一步进入该stop()方法，我可以看到异常来自releaseExternalResources. 上面的代码是从Netty Reasteasy复制的

有没有人使用这个代码没有任何问题？有人可以指导我吗？谢谢。更新：这是堆栈跟踪：

问题是 start 方法中的 NettyJaxrsServer 创建了一个从未全局保存的私有引导对象。因此，当您点击 stop 方法时，全局引导引用为空。奇怪的小姐。
