Spring 将 Amazon RDS 端点放入数据源时，启动应用程序不会 运行 URL
Spring boot app does not run when putting Amazon RDS endpoint to the datasource URL
我的应用程序在使用 Postgres 进行测试时在本地 运行 正常。但我正在尝试连接到我的 RDS 数据库，该数据库的状态为：'Available' 且可公开访问：'Yes'。

在数据源 URL 中使用 Amazon RDS 端点更新属性文件时 运行 应用程序出现错误。属性文件中的用户名和密码也是正确的。
Application.properties file image
Intellij 控制台的错误是：

如有任何建议，我们将不胜感激。
注意spring并不是抱怨错误username/password。它甚至无法连接到数据库来检查 username/password 是否正确。
这表示存在网络问题（即您的计算机与 RDS 实例之间没有网络连接）。
请检查您的安全组是否允许从您的 IP
