java - How set up Spring Boot to run HTTPS / HTTP ports

Question

Spring boot have some properties to config web port and SSL settings, but once a SSL certificate is set the http port turns into https port.

So, how can I keep both ports running on it, for example: 80 an 443 at the same time?

As you can see, there only properties for one port, in this case "server.ssl" is enabled, what makes http port be disabled automatically.

##############
### Server ###
##############
server.port=9043
server.session-timeout=1800
server.ssl.key-store=file:///C:/Temp/config/localhost.jks
server.ssl.key-store-password=localhost
server.ssl.key-password=localhost
server.ssl.trust-store=file:///C:/Temp/config/localhost.jks
server.ssl.trust-store-password=localhost

I am trying to use even Tomcat or Undertow. I'd appreciate any help!

Spring Boot configuration using properties, allows configuring only one connector. What you need is multiple connectors and for this, you have to write a Configuration class. Follow instructions in

https://docs.spring.io/spring-boot/docs/1.2.3.RELEASE/reference/html/howto-embedded-servlet-containers.html

You can find a working example of configuring HTTPS through properties and then HTTP though EmbeddedServletContainerCustomizer below

server:
  port: 8080
  ssl:
    enabled: true
    keyStoreType: PKCS12
    key-store: /path/to/keystore.p12
    key-store-password: password
  http:
    port: 8079

@Configuration
public class TomcatConfig {

@Value("${server.http.port}")
private int httpPort;

@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
    return new EmbeddedServletContainerCustomizer() {
        @Override
        public void customize(ConfigurableEmbeddedServletContainer container) {
            if (container instanceof TomcatEmbeddedServletContainerFactory) {
                TomcatEmbeddedServletContainerFactory containerFactory =
                        (TomcatEmbeddedServletContainerFactory) container;

                Connector connector = new Connector(TomcatEmbeddedServletContainerFactory.DEFAULT_PROTOCOL);
                connector.setPort(httpPort);
                containerFactory.addAdditionalTomcatConnectors(connector);
            }
        }
    };
}
}
