我可以将CDI注入石英调度程序作业吗？ [英] can I use CDI injection into quartz-scheduler jobs?

问题描述

我使用Glassfish和CDI进行注射，（主要是）成功。我似乎无法让Quartz工作与注释bean一起工​​作，注释中注有 @Inject 永远不会被注入。

I'm using Glassfish and CDI for injection, (mostly) successfully. I can't seem to get Quartz jobs to work with injection- beans annotated with @Inject never get injected.

是否Quartz使用某种不同的类加载器来防止注入发生？

Is Quartz using some kind of different classloader that's preventing injection from happening?

我在我的web.xml中配置Quartz：

I'm configuring Quartz like so in my web.xml:

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

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

我的quartz.properties看起来像：

My quartz.properties looks like:

org.quartz.scheduler.instanceName = MyScheduler
org.quartz.scheduler.instanceId = 1
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false

org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 3

org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin
org.quartz.plugin.jobInitializer.fileNames = quartz-config.xml
org.quartz.plugin.jobInitializer.scanInterval = 10
org.quartz.plugin.jobInitializer.wrapInUserTransaction = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true

推荐答案

你需要自己实现org.quartz.spi.JobFactory，它知道如何使用你的应用程序n的CDI实例化作业类并注入它们。

You will need to make your own implementation of org.quartz.spi.JobFactory that knows how to use your application's CDI to instantiate the jobs classes and inject them.
