  1. Create Self Signed SSL Certificate

    keytool -genkeypair -alias filenameAlias -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore filename.p12 -validity 3650

    And use below code to view certificate details.

    keytool -list -keystore  filename.p12

  2. Enabling HTTPS in Spring Boot application.propreties

    # The format used for the keystore. for JKS, set it as JKS
      server.ssl.key-store-type=PKCS12
    # The path to the keystore containing the certificate
      server.ssl.key-store=classpath:keystore/javadevjournal.p12
    # The password used to generate the certificate
    server.ssl.key-store-password=use the same password which we added during certificate creation
    # The alias mapped to the certificate
      server.ssl.key-alias=javadevjournal
    # Run Spring Boot on HTTPS only, default 443 like no https 80 port
    server.port=8443

Note that you need copy filename.p12 to src/main/resources/keystore folder
