Logback：使用Groovy配置启用shutdownHook

我使用logback 1.1.10和groovy配置。我最近发现shutdownHook preference，但我还没有找到使用groovy配置来启用它的方法。这可能吗？还是缺少一个功能？Logback：使用Groovy配置启用shutdownHook

Logback的shutdownHook已添加到v1.3中，并且可以使用Groovy进行配置。该docs有点轻在这个问题上和xml->groovy translator忽略shutdownHook但我如下已经验证通过Groovy的配置纳入关闭挂钩的：

import ch.qos.logback.classic.AsyncAppender 
    import ch.qos.logback.classic.PatternLayout 
    import ch.qos.logback.classic.encoder.PatternLayoutEncoder 
    import ch.qos.logback.core.ConsoleAppender 
    import static ch.qos.logback.classic.Level.INFO 

    scan("30 seconds") 

    statusListener(OnConsoleStatusListener) 

    def shutdownHook() { 
     def shutdownHook = new ch.qos.logback.core.hook.DelayingShutdownHook(); 
     shutdownHook.setContext(context); 

     def Thread hookThread = new Thread(shutdownHook, "Logback shutdown hook [" + context.name + "]"); 
     context.putObject("SHUTDOWN_HOOK", hookThread); 
     Runtime.getRuntime().addShutdownHook(hookThread); 
    } 

    shutdownHook(); 

    appender("Console-Appender", ConsoleAppender) { 
     encoder(PatternLayoutEncoder) { 
      pattern = "%d|%-5p|%t|%msg%n" 
     } 
    } 

    logger("com", INFO, ["Console-Appender"], false) 

    root(INFO, ["Console-Appender"])

这是通过运行一个Java程序，其使用的logback证实，通过使用-Dlogback.configurationFile明确指着上面的配置，并输出结果清楚地显示正在使用的关闭挂钩：

谢谢您的回答！我会测试它。关于它的一个小评论，今天最后一个1.1版logback系列的可下载版本是1.1.10。没有1.1.13版本（尚未）。看看[下载dist页面]（https://logback.qos.ch/dist/） – guindous

道歉，我在我的回答中提到了1.1.3和1.1.13。正确的版本（即引入shutdownHook的版本）是1.1.3。因此它在1.1.10中可用。而且，由于您使用的是1.1.10，因此无需升级，只需按照我提供的用于在logback.groovy中定义shutdownHook的说明进行操作即可。我已经更新了我的答案。 – glytching
