日志信息 “info shutdownhookmanager: shutdown hook called” 表示 ShutdownHookManager(一个管理 shutdown hook 的组件)已经触发了一个 shutdown hook。这通常意味着 JVM 正在执行关闭序列,且已注册的 shutdown hook 正在被执行。 4. 提供可能导致该日志信息出现的原因 该日志信息出现的原因通常与 JVM 的关闭过...
public void addShutdownHook(Thread hook) 参数: hook - An initialized but unstarted Thread object 抛出: IllegalArgumentException - If the specified hook has already been registered, or if it can be determined that the hook is already running or has already been run IllegalStateException - If th...
用户通过Runtime.getRuntime().addShutdownHook()方法来注册关闭钩子,示例: Runtime.getRuntime().addShutdownHook(newThread(()->{someThreadPool.shutdown();someConnectionPool.close();LOGGER.info("Shutdown hook called");})); 可见,关闭钩子的本质就是已经初始化但在JVM关闭之前最后一刻才会执行的线程。

Execute Hook... 可以看到程序遇到内存溢出错误后调用关闭钩子,与第一种情况中,程序等待5000ms运行结束之后推出调用关闭钩子不同。 接下来再来测试第三种情况: package com.hook; import java.util.concurrent.TimeUnit;publicclassHookTest3 {publicvoidstart() { ...

1、JVM自带的shutdownHook Runtime.getRuntime().addShutdownHook(newThread(()->log.info("shutdown hook, jvm demo"))); 特点: jvm自带,使用方便,多个钩子间是并行执行的。 2、监听Spring的ContextClosedEvent 关于ContextClosedEvent等事件描述,可以参照以下示例(内容来自Spring官网) ...
