在创建调度程序时，我发现无法在其中使用 CDI 注入，经过一些研究，我发现了一个有趣的解决方案，即使用 API deltaSpike 的调度程序模块。

我遵循了官方文档中描述的所有步骤，所以我在我的 pom.xml 中添加了以下依赖项

<dependencyManagement>

        <scope>runtime</scope>
    </dependency>

但是每次启动我的 jboss 服务器时都会抛出这个异常

关于异常我错过了有关 deltaspike 配置的一些内容，但我在 stackoverflow 或任何其他网站中都没有找到任何东西，请帮助

好吧，问题解决了，我对 deltaSpike 很感兴趣，因为我试图弄清楚如何在 CDI 上下文中使用 Quartz。

经过一番研究，我发现 EJB Timer 非常适合我，因为我们使用的是 JBOSS AS whitch 实际上是一个 ejb Container。
