Java 为什么'；无法在aws elasticbeanstalk上登录我的springboot应用程序？

部署在aws elasticbeanstalk上的war应用程序不会写入任何日志。 我也有类似的问题。为了测试和简化，我将一个新的空war项目部署到Tomcat 8.5中，该项目由maven在OpenJDK Java11上构建的Spring框架Initializer（）生成，Corretto 11在64位Amazon Linux 2/4.1.1上运行

我使用slf4j记录器。 和一些信息级日志记录。在localhost上运行良好

在aws elb上是/var/log/tomcat/catalina.2020-11-05.log日志文件，启动后我只能看到以下日志：

我的应用程序缺少我的信息日志或任何其他springboot日志。
在Java1.8上的ELB的早期版本中，它运行良好。发生了什么变化？如何再次打开日志记录

谢谢你的建议

这是我们的JavaSpring应用程序中的问题。错误的devel配置。 在application.properties中，这是一行

logging.file.name=log/synchronization.log

我一眼就没注意到。在application-production.properties中，与日志记录无关，因此此配置会影响生产，并且所有日志都会写入此文件（路径错误，因为在aws eb（tomcat）上是日志记录目录/not log/）。这就是为什么我无法在标准日志路径less/var/log/tomcat上看到日志/

我将application-production.properties更改为

logging.file.name=logs/my-app.log

就是这样。它现在可以工作了。
