Quartz 似乎找不到 shutdownhook 插件。当我将以下行添加到quartz.properties 文件以安全关闭时，就发生了这种情况。

org.quartz.plugin.shutdownhook.cleanShutdown=TRUE

有什么想法如何将 shutdownhook 添加到quartz 中吗？

Answer 1

在以下配置行之前:

org.quartz.plugin.shutdownHook.cleanShutdown=TRUE

添加以下行:

org.quartz.plugin.shutdownHook.class=org.quartz.plugins.management.ShutdownHookPlugin

如suggested在 quartz 官方网站(在页面底部)。
