Spring boot Spring Boot—捆绑在依赖jar中的类路径资源在一段时间后停止工作，并出现关于上次修改的时间戳的错误

我们有spring启动应用程序，它在lib中包含依赖的项目jar。这些依赖jar具有资源文件。在生产环境中运行一段时间后（大约3-4天，没有特定模式），它停止工作并抛出以下异常。 我们使用的是spring boot1.5.3.RELEASE版本

在maven插件配置中，我们也为那些依赖的JAR使用了requiresUnpack，正如某些地方所建议的那样，但在服务内容成功发布几天后仍然给出了上述错误

您应该尝试将Spring版本更新到高于4.3.x的版本，这意味着您可以尝试更新Spring启动版本，最新的1.5.x版本为1.5.22.RELEASE

这个问题在Spring4.3.x的某些版本中得到了修复，如中所示。

---

较旧版本的存在此问题。

您在prod环境中部署的服务器是什么？我们正在aws elastic beanstalk上部署此应用程序，服务器嵌入tomcat，位于nginx后面。好的，感谢您提供的指针，我们将尝试使用最新版本，看看它是否解决了此问题。
