Question

我们通过xml文件配置了3个quartz.net（版本2.3.3）作业

IInterruptableJob Job1Class用DisallowConcurrentExecution标记，并被Job1＆amp;在xml文件中的Job2（当然具有不同的作业数据）。

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，2个作业长时间运行，我们要求所有3个作业应该并行执行，但很多时候我们发现它不执行并行。那么为什么它不能并行执行。

以下是示例xml文件。

Answer 1

Job1和Job2无法并行运行，因为您告诉Quartz Job1Class具有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，请从Job1Class中删除DisallowConcurrentExecution属性，并从Job1Class创建2个子类。一个用于Job1，一个用于Job2。然后给每个新类赋予属性，它应该像你想要的那样工作。

quartz.net 2.0作业不执行并行
