Question

我试图解决避免长时间加载默认quartz.properties文件的问题。希望有人能在这里伸出援助之手。非常感谢！

基本上，我已经阅读了很多关于这个问题的帖子，而他们的解决方案并没有解决我的问题。我已将quartz.properties文件放在WEB-INF / classes下，以下是我在web.xml中使用上下文监听器的配置：

<context-param>
    <param-name>quartz:config-file</param-name>
    <param-value>quartz.properties</param-value>
</context-param>

<context-param>
    <param-name>quartz:shutdown-on-unload</param-name>
    <param-value>true</param-value>
</context-param>

<context-param>
   <param-name>quartz:wait-on-shutdown</param-name>
   <param-value>true</param-value>
</context-param>

<context-param>
   <param-name>quartz:start-on-load</param-name>
   <param-value>true</param-value>
</context-param>

<listener>
   <listener-class>
       org.quartz.ee.servlet.QuartzInitializerListener
   </listener-class>
</listener>

结果仍然显示如下：

[INFO] 18 Feb 06:37:29.218 PM main [org.quartz.impl.StdSchedulerFactory]

我遇到的另一个困惑是，如果它真的加载了默认的quartz.properties文件，那么为什么根据我自定义的quartz.properties文件正确设置了线程池和调度程序名称？

另一方面，我还尝试根据Quartz的官方文档QuartzInitializerListner为quartz.properties文件设置不同的路径。例如：

<context-param>
     <param-name>quartz:config-file</param-name>
     <param-value>/MyProject/WEB-INF/my_quartz.properties</param-value>
</context-param>

结果显示更糟糕。这将是完全默认的设置。因此，我现在很迷茫。请详细说明这种情况的根本原因。非常感谢你！

我修复了这个问题，将 quartz.properties 放在我的资源文件夹（src / main / resources）中。

您的上下文Param应如下所示：

<context-param>
     <param-name>quartz:config-file</param-name>
     <param-value>quartz.properties</param-value>
</context-param>

看一下石英的代码：

InputStream is = null;
Properties props = new Properties();
is = Thread.currentThread().getContextClassLoader().getResourceAsStream(filename);

其中 filename 是属性文件。

因此，它尝试将文件作为Stream。请查看Java Doc：
