This project demonstrates how to get started with using SSL on a Embedded Jetty Server in Spring Boot and to perform HTTP/2 Request.

Initially, you will need to get rid of using Tomcat from started-web. And include jetty in build.gradle.

1. Generate Self-Signed Certificate using keytool. keytool is bundled with JDK, so it has to be available already.
2. Put the generated .jks file under src/main/resources. During Start up, the files in this directory gets copied to classpath.
3. Look at the application.properties for a sample path using classpath.
4. When the server starts up, the jks file is read from classpath and SSL is supported by the Spring Boot Application.

Still the request will be using HTTP1.1 since JDK8 does not support HTTP/2 out of box.

So, we need to include the conscrypt library as in build.gradle.

Now, perform curl -v https://localhost:8080/greeting which gives info that it is connected through HTTP2. Then, perform curl -v -k https://localhost:5432/greeting which uses traditional HTTP1.1 for serving the request.

Hence, we have achieved HTTP/2 using Jetty and Spring Boot using the Conscrypt Library.
