那些遇到过的问题

将Spring Boot应用程序部署到Elastic Beanstalk时出现502 Bad Gateway

Pet*_*ter 0 java spring amazon-web-services spring-boot amazon-elastic-beanstalk

免责声明*我知道对此有很多疑问。我已经查看了他们并应用了答案，但仍然无法正常工作。

我使用.jar（不是war）文件将Spring Boot应用程序部署到Elastic Beanstalk。我正在使用Java 1.8。我将application.properties更改为server.port =5000。我还打开了我的ec2实例用于0.0.0.0/32上的端口5000的安全组。当我的弹性beantalk环境加载时，状态降级。这是来自EB的日志文件。

最可能的情况是应用程序服务器（嵌入式Spring Boot）无法正确启动。应用程序服务器的日志存储到/var/log/web-1.logElasticBeanstalk中的“日志”选项卡中，也可以通过“日志”选项卡使用。

以我的经验，这通常与无法访问支持的服务（数据库集群）有关。从您的ElasticBeanstalk EC2环境到RDS数据库的安全组可能未正确设置。
