AWS中Java Sping引导应用程序部署问题的服务器健康状态错误

Question

>

我正在尝试在AWS弹性Bean stalk中部署Java Spring Boot应用程序

i上传应用程序代码和zip格式的jar文件，并更改了代码和AWS的服务器端口

应用程序已部署，但服务器运行状况显示为降级

你能告诉我如何使API成为公共的吗

你们能告诉我你们的建议哪里出错了吗

应用程序代码可在github及其链接中获得:https://github.com/aarivalagan/student-application/blob/master/studentcousr.zip

我在下面附上了应用程序服务器截图:

下面提供部署日志文件和application.properties文件：

Application.Properties文件

SERVER_PORT = 5000

Answer 1

默认情况下，elb使用端口5000，它作为名为port的env变量公开，您需要在应用程序中使用它。

server_port是一个elb参数，不用于Spring Boot。

将server.PORT=${PORT}放入application.properties中。

eb setenv server_port=8001

使用AWS CLI
