在AWS Beanstalk上部署SpringBoot - 应用程序启动，连接到RDS-DB，但浏览器无法连接。

Question

我现在正在学习AWS，因此现在将我的spring boot应用部署在AWS Elasctic Beanstalk上，并将其连接到我放在AWS RDS上的mariaDB数据库。这很成功! 我可以看到我的数据库中的测试条目，而且Elastic Beanstalk日志文件也显示Spring应用已经启动，健康检查也是OK的。

但是当我点击App的链接时 studileih.eu-central-1.elasticbeanstalk.com我得到一个404.我也试过 studileih.eu-central-1.elasticbeanstalk.com5000因为我的spring boot应用是在5000端口启动的（我把它从8080改成5000，因为我认为ElasticBeanstalk需要5000端口？studileih.eu-central-1.elasticbeanstalk.com所有产品。 和 studileih.eu-central-1.elasticbeanstalk.com5000所有产品。 因为allProducts是我get请求的端点。

这是直接在浏览器中得到的结果。
