我们通过 xml 文件配置了 3 个quartz.net（版本 2.3.3）作业

IInterruptableJob Job1Class 被标记为 DisallowConcurrentExecution 并被 xml 文件中的 Job1 和 Job2（当然具有不同的作业数据）使用。

IInterruptableJob Job3Class 由 Job3 在 xml 文件中使用。

quartz.threadPool.threadCount 通过配置文件设置为 6。

在 3 个作业中，有 2 个作业长时间运行，我们要求所有 3 个作业都应该并行执行，但很多时候我们观察到它不会并行执行。那么为什么它不并行执行。

下面是示例 xml 文件。

Job1并且Job2不能并行运行，因为您告诉 QuartzJob1Class具有该DisallowConcurrentExecution属性。此属性适用于类，而不适用于对象。Quartz 不会运行多个 Job1Class 实例。要解决此问题，DisallowConcurrentExecution请从 Job1Class 中删除该属性并从Job1Class. 一个用于 Job1，一个用于 Job2。然后为每个新类赋予属性，它应该像你想要的那样工作。
