Spring boot 如何防止在加载上下文后立即执行Spring批处理作业
我是SpringBatch的新手,现在,我有一个从Quartz调度器触发SpringBatch作业的示例。我的应用程序是通过使用SpringBoot加载Spring上下文启动的 我的问题是,每次加载完应用程序上下文后,spring批处理作业都会立即执行,这是出乎意料的。之后,该作业由Quartz触发,作为在cron表达式中设置的时间 我希望有一个解决方案,用于删除在加载spring上下文之后立即发生的作业的第一次运行。谁能给我一个方法吗 下面是我的配置文件,我的作业名为“importUserJob”Spring boot 如何防止在加载上下文后立即执行Spring批处理作业,spring-boot,spring-batch,Spring Boot,Spring Batch,我是SpringBatch的新手,现在,我有一个从Quartz调度器触发SpringBatch作业的示例。我的应用程序是通过使用SpringBoot加载Spring上下文启动的 我的问题是,每次加载完应用程序上下文后,spring批处理作业都会立即执行,这是出乎意料的。之后,该作业由Quartz触发,作为在cron表达式中设置的时间 我希望有一个解决方案,用于删除在加载spring上下文之后立即发生的作业的第一次运行。谁能给我一个方法吗 下面是我的配置文件,我的作业名为“importUserJo
