Http to Https AWS Elasticbeanstalk

Question

I am using AWS Elasticbeanstalk for my Spring MVC web application. I want to redirect all the request to https. I tried following this How to force https on elastic beanstalk? but this didn't work for me. This code redirects to https but my app didn't work. It shows "This page isn’t working". Code for your reference

<VirtualHost *:80>
  RewriteEngine on
  RewriteCond %{HTTP:X-Forwarded-Proto} =http
  RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
  <Proxy *>
    Order Allow,Deny
    Allow from all
  </Proxy>
  ProxyPass / http://localhost:8080/ retry=0
  ProxyPassReverse / http://localhost:8080/
  ProxyPreserveHost on

  ErrorLog /var/log/httpd/elasticbeanstalk-error_log
</VirtualHost>

Assuming you've already tested HTTPS working fine when your website is visited with HTTPS already. If not you can add this file .ebextensions/loadbalancer-terminatehttps.config with content as below:

option_settings:
  aws:elb:listener:443:
    ListenerProtocol: HTTPS
    SSLCertificateId: arn:aws:acm:us-west-2:<your-account-id>:certificate/<certificate-arn-on-aws-acm>
    InstancePort: 80
    InstanceProtocol: HTTP

All what's left is to configure the instances Apache config to redirect the clients visiting your website with HTTP to HTTPS, add the code below to a new file .ebextensions/001_ssl_rewrite.config

Apache 2.4+

files:
    "/etc/httpd/conf.d/ssl_rewrite.conf":
        mode: "000644"
        owner: root
        group: root
        content: |
            RewriteEngine On
            <If "-n '%{HTTP:X-Forwarded-Proto}' && %{HTTP:X-Forwarded-Proto} != 'https'">
            RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
            </If>

Apache 2.2.X

files:
    "/etc/httpd/conf.d/ssl_rewrite.conf":
        mode: "000644"
        owner: root
        group: root
        content: |
            LoadModule rewrite_module modules/mod_rewrite.so
            RewriteEngine On
            # This will enable the Rewrite capabilities
            RewriteCond %{HTTPS} !=on
            # This checks to make sure the connection is not already HTTPS
            RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
