石英调度程序无法获取触发器

Question

我正在与一位客户合作，但遇到了不时触发作业的问题。

这里是一个错误示例，这种情况经常发生，也会导致作业无法触发。

我有类似的问题。 Quartz 抱怨 死锁或超时 - 类似于您的堆栈跟踪。就我而言，异常消息有点误导，因为它实际上意味着根本没有连接到数据库。

• 根据quartz documentaiton，确保您满足使用JobStoreCMT 的要求：

  ...在尝试安排（或取消安排）作业/触发器之前，JTA 事务必须正在进行。这允许调度的“工作”成为应用程序“更大”事务的一部分......

• 请注意 - 只要使用 SimpleThreadPool，您的计划作业就会在 非托管线程（Websphere 之外）中运行。非托管线程无权访问服务器上下文（包括数据源、jndi 等）

• 考虑使用JobStoreTX 并在WorkManagers 提供的托管线程中运行作业，请参阅discussion 和my answer 与github-example。
