Java 关闭时的Execute方法引发log4j非法状态异常无法注册关闭

我想在退出swing应用程序时关闭连接。 因此，正如这里所建议的：

我在主线程中添加了以下代码，最终得到以下堆栈跟踪。它确实执行我的closeConnections方法

/** on exit */
         Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {

                public void run() {
                     DeviceManager.getInstance().closeConnections();
                    //shutdown log4j2
                    if( LogManager.getContext() instanceof LoggerContext ) {
                        LogManager.getLogger().info("Shutting down log4j2");
                        Configurator.shutdown((LoggerContext)LogManager.getContext());
                    } else{
                        LogManager.getLogger().warn("Unable to shutdown log4j2");}

                }

            }, "Shutdown-thread"));

我认为log4j也有一个shutdown钩子，shutdown钩子的执行顺序由JVM决定，所以您不能影响它。我可能可以禁用log4j shutdownhook并自己进行清理，但最好检查log4j的功能。

尝试获取LoggerContext状态并在关闭之前对其进行测试：（LoggerContext）LogManager.getContext（）.getState（）@jMounir getState（）方法不存在您建议的方式。很抱歉我弄错了，应该这样调用它：（（LoggerContext）LogManager.getContext（））.getState（）@jMounir我已经在run方法的顶部添加了它。我开始了。原始帖子中显示的错误显示在“state=started”打印输出之前。您将此代码放在何处。因为我看到了关于退出的评论*/你是指退出事件吗？。因为当程序
