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

【中文标题】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【英文标题】：Deploying SpringBoot on AWS Beanstalk - app starts, connects to RDS-DB, but browser can't connect 【发布时间】：2020-10-02 15:39:37 【问题描述】：我现在正在学习 AWS，因此现在将我的 Spring Boot 应用程序部署在 AWS Elasctic Beanstalk 上，并将其连接到我放在 AWS RDS 上的 mariaDB 数据库。那是成功的！我可以在我的数据库中看到测试条目，并且 Elastic Beanstalk 日志文件显示 Spring 应用程序已启动并且运行状况检查正常。
但是当我点击应用程序studileih.eu-central-1.elasticbeanstalk.com 的链接时，我得到一个 404。 我还尝试了studileih.eu-central-1.elasticbeanstalk.com/5000，因为我的 Spring Boot 应用程序在端口 5000 上启动（我将其从 8080 更改为 5000，因为我认为 ElasticBeanstalk 需要端口 5000？）studileih.eu-central-1.elasticbeanstalk.com/allProducts 和 studileih.eu-central-1.elasticbeanstalk.com/5000/allProducts 因为 /allProducts 是我获取的端点要求。

【问题讨论】：
【参考方案1】：我以为我已经将安全组入站规则设置为“允许来自任何地方的所有流量”，但这是错误的。添加它们后，它与 http://studileih.eu-central-1.elasticbeanstalk.com/allProducts 一起工作（不需要端口 5000）奇怪的是 HTTP 规则还不够强硬......：
那是直接在浏览器中的结果：
