Problem to deploy web app spring on elastic beanstalk. Return 404

Question

https://github.com/488442/vm

This is my GitHub of the project , when i deploy it on amazon web services (elasticbeanstalk) and i try to open it , return only 404 obviously on Tomcat server work perfectly. I have tried everything , exporting the project in war file.

this is the code of application

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public RequestContextListener requestContextListener() {
        return new RequestContextListener();
    }

EDIT: the resource work at 100% in localhost with Starting Servlet Engine: Apache Tomcat/8.5 and it's the same version on AWS.

This is the log from AWS , any ideas?

some news?

Answer 1

Solved, I have changed was rds setting security

Answer 2

What does your source bundle look like? The docs state that a requirement for the archive is that it must "[n]ot include a parent folder or top-level directory" but your GitHub repo has a top-level directory. You might also want to enable CloudWatch logs or retrieve the instance logs to get a better idea of where the web server is looking for files.

Here is an example bundle structure that might help.

Answer 3

In your code I see that you set your server.port to 8081 in application.properties. Try to remove this line to have it running on the default port.

EDIT:

Regarding the docs (https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-se-nginx.html) it seems to me that Beanstalk listens on port 5000 by default. So at this point you can do one of the followings:

1. Set your application's server.port property to 5000, or
2. Override your Beanstalk instance's default by setting the PORT environment variable to match with your application's port (in your case, it's 8081).
