Apache2 redirect to https - http

Question

For one of my customer projects, I have a domain name abc.my-app.com. My server public IP is x.y.z.a .
I have developed a Spring boot based application. In the application, I have configured automatic redirect from http port 8088 to https 8443.
The application is accessible as https://x.y.z.a:8443/ without issues.
The application is also redirected to https when accessed as http://x.y.z.a:8088
in the browser.
Refer https://drissamri.be/blog/java/enable-https-in-spring-boot/ on how I have configured this.
I also have setup apache 2.4.18 version on my server. I have configured virtual hosts to be able to redirect to https when my application is accessed from browser as https://abc.my-app.com to https://abc.my-app.com:8443.
But, if user accesses http://abc.my-app.com (without https), the apache does not redirect to my application on https.
How do I enable Apache to redirect from http://abc.my-app.com to https://abc.my-app.com?
My Virtual host configuration is below:
<VirtualHost *:80 *:8080 *:443>
ServerAdmin webmaster#xyzc
DocumentRoot /var/www/
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLEngine On
SSLProxyEngine On
SSLCertificateFile /etc/apache2/ssl/ca.crt
SSLCertificateKeyFile /etc/apache2/ssl/ca.key
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName Off
ProxyPreserveHost On
# Servers to proxy the connection, or
# List of application servers Usage
ProxyPass / https://x.y.z.a:8443/
ProxyPassReverse / https://x.y.z.a:8443/
ServerName ip-x-y-z-a
</VirtualHost>`

Answer 1

I finally got it working. Not sure though this is the right way.
In Spring boot application, I configured redirect from port 80 to port 443.
Apache2 redirects from 443 to my application running on port 8443.
