quartz-scheduler - web.xml 中的 Quartz 属性文件配置及其位置

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，但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，以下是我使用上下文监听器在 web.xml 中的配置:

<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>

结果还是这样:

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

另一方面，我也尝试根据Quartz的官方文档为quartz.properties文件设置不同的路径:QuartzInitializerListner .例如:

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

结果更糟。这将是完全默认设置。因此，我现在很迷路。请详细说明这种情况的根本原因。非常感谢你!

我将 quartz.properties 放在我的资源文件夹 (src/main/resources) 中解决了这个问题。

你的上下文参数应该是这样的:

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

看看 quartz 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，它尝试将文件作为流获取。请检查 Java 文档:
