java - Spring 没有运行我的 @Scheduled(cron = "0,30 * * * * *")

Question

• 以下是代码
• 我现在正在使用 spring.boot.version 1.4.1.RELEASE
• 启动服务器时没有打印任何内容
• 我正在使用 @Scheduled 注释来运行 cron 作业，但它永远不会启动
• 如果我创建新项目并使用以下类，则相同的代码可以正常工作

• 请建议可能出现什么问题？

您的代码示例对我来说看起来非常好。此外，我已经使用您提供的示例代码创建了一个项目，并且它可以正常工作（使用 spring.boot.version 1.2.1.RELEASE ）。

github上有一个类似的项目，你可能会感兴趣。
