无法在Amazon EC2实例上运行war文件

Question

我正在使用最新的Angular 7开发Spring Boot应用程序。我已经创建了一个构建并生成了war文件。

我已经在其中配置了一个文件夹，其结构为：

project-tool.war
config/application-prod.yml
config/application-dev.yml
config/application.yml
run.sh 
run.bat

在run.sh/run.bat中，这些命令写为-> java -jar project-tool.war --spring.profiles.active = prod --spring.config.location = config \\ application-prod.yml

我已经在AWS上创建了Oracle数据库实例，并将配置放在application-prod.yml中。

然后，我已经在Windows OS上使用war文件运行了该项目，效果很好。

我必须在Amazon EC2实例上运行此war文件。 因此，我已将此文件夹上传到EC2中型实例上。 当我运行它时，它抛出一个错误：

我也有另一个实例和其他项目（spring和angularJS）以类似的方式很好地工作。 但是为什么这不起作用，命令或角度有问题吗？

如何在Amazon EC2上工作？

Answer 1

您在这里读取错误堆栈跟踪的问题是数据库连接。 请注意核心错误消息无法初始化池：IO错误：网络适配器无法建立连接

我不知道oracle数据库的配置方式，但是您可能在数据库侦听器配置方面遇到了问题，或者更简单地说，我可以建议尝试在安全组和网络配置上查看EC2和Oracle Database实例之间的网络通信。 问题不是Angular，而是您的应用程序与数据库之间的数据库链接。

希望对您有所帮助
