Setting up HTTPS for Spring Boot requires two steps:
- Getting an SSL certificate;
- Configuring SSL in Spring Boot.
We can generate an SSL certificate ourselves (self-signed certificate). Its use is intended just for development and testing purposes. In production, you should use a certificate issued by a trusted Certificate Authority (CA). Whether you’re going to generate a self-signed certificate or you have already got one by a CA, I’ll show you how to enable HTTPS in a Spring Boot application.
In this tutorial I’ll explain how to:
- Get an SSL certificate
- Generate a self-signed SSL certificate
- Use an existing SSL certificate
- Enable HTTPS in Spring Boot
- Redirect HTTP requests to HTTPS
- Distribute the SSL certificate to clients.
