How can I set up a letsencrypt SSL certificate and use it in a Spring Boot application?

Question

I\'m new to securing a server so I don\'t really know much about this but I need to get my Spring Boot Application that is running on a Digital Ocean Droplet to use HTTPS. <

Answer 1

1. Get an SSL certificate from letsencrypt
2. Add it into a keystore using the keytool command in Java
3. Configure your Spring application to use the keystore generated above

The file should look like:

 server.port = 8443
 server.ssl.key-store = classpath:sample.jks
 server.ssl.key-store-password = secret
 server.ssl.key-password = password
