502 bad request on AWS Spring boot application

Question

Hi I am new AWS and trying to deploy spring boot application in Elastic Beanstalk . Deployment is successful but not able to access application .Getting 502 Bad Request Gate

Answer 1

From AWS documentation:

By default, Spring Boot applications will listen on port 8080. Elastic Beanstalk assumes that the application will listen on port 5000. There are two ways to fix this discrepancy: change the port Elastic Beanstalk is configured to use, or change the port the Spring Boot application listens on.

You can set the port in server.port property in application.properties or set it through environment as described in the document referred above by setting SERVER_PORT environment property.

I also had the same issue. And the reason was the fact that i didn't correctly generate my jar. Instead of taking the classic jar from an clean install take the one from a clean package spring-boot:repackage
