aws ec2 my spring boot is runnig on port 8080 and I need to run on 80

Question

I have configure AWS EC2 linux instance . So I run my spring boot app on that instance. So When I start my app its post is 8080 so after deployment and my app is active then URL is like : 55.12.15.78:8080/myapp/

Can any one help how to run my app with port 80 so I can access my app by 55.12.15.78/myapp/ or any way to work on that way.

Now I have domain name and I have configure the AWS ROUTE 53 service and its up also but when I hit the app I need to enter the URL like : www.myapp.com:8080/myabb/

Which is my issue.

I head by using the instance load balancer we can do that. But I do not have any idea to configure that too.

Answer 1

I just run my application on ec2 with this commend and server get started.

java -Dserver.port=80 -jar myapp.war

Also I configured load balancer of EC2 which will handle https request.

Answer 2

The default port where a Spring Boot app runs is 8080. You can edit your application.properties or application.yml file and change the port to 80. Re-start the application, your application should be running on port 80 then.

# application.properties
server.port=80

or

# application.yml
server:
  port : 8081

There are many other ways to configure the port in a Spring Boot application. You can find more details here: https://www.baeldung.com/spring-boot-change-port
