Configure Spring Boot with two ports

I'm trying configure an application in Spring Boot with two differents ports, but I haven't got still. My first approximation has been with two controllers and I have defined a @Bean inside the two controller with container.setPort(8080); And my second approximation has been add the actuator dependency and change the port of the management, but my application don't run. It shows:

Address already in use: bind

How can I confiure an application with two ports? I want one port for admin and the other port is for consults of my api.

As is has been mentioned before, server.port and management.port along with management.context-path properties could be set to make the embedded container to listen on different ports (management-related properties to access Actuator endpoints).

To listen on ports other than server.port and management.port:

@Configuration
public class EmbeddedTomcatConfiguration {

    @Value("${server.additionalPorts}")
    private String additionalPorts;

    @Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
        Connector[] additionalConnectors = this.additionalConnector();
        if (additionalConnectors != null && additionalConnectors.length > 0) {
            tomcat.addAdditionalTomcatConnectors(additionalConnectors);
        }
        return tomcat;
    }

    private Connector[] additionalConnector() {
        if (StringUtils.isBlank(this.additionalPorts)) {
            return null;
        }
        String[] ports = this.additionalPorts.split(",");
        List<Connector> result = new ArrayList<>();
        for (String port : ports) {
            Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
            connector.setScheme("http");
            connector.setPort(Integer.valueOf(port));
            result.add(connector);
        }
        return result.toArray(new Connector[] {});
    }
}

application.yml

server:
  port: ${appPort:8800}
  additionalPorts: 8881,8882

Application.java

@SpringBootApplication
@ComponentScan(...)
@Import(EmbeddedTomcatConfiguration.class)
public Application {

    public static void main(String[] args) {
        SpringApplication.run(Application .class, args);
    }
}

If only one additional port is to be opened, the following is sufficient (Kotlin):

@Configuration
class AdditionalEndpointConfig {

    @Bean
    @ConditionalOnProperty(PORT_PROPERTY)
    fun tomcatServletWebServerFactory(@Value("\${$PORT_PROPERTY}") additionalPort: Int) =
        TomcatServletWebServerFactory().apply {
            addAdditionalTomcatConnectors(
                Connector("org.apache.coyote.http11.Http11NioProtocol").apply {
                    scheme = "http"
                    port = additionalPort
                })
        }

    companion object {
        const val PORT_PROPERTY = "server.additional.port"
    }
}

To run 2 or more applications within a single project or change the default port, you can perform the action like this

@SpringBootApplication
public class NewApplication {
     public static void main(String[] args) {
         SpringApplication app = new SpringApplication(NewApplication .class);
         app.setDefaultProperties(Collections.singletonMap("server.port", "8083"));
         app.run(args);
     }
}

Since springboot 2, EmbeddedServletContainerFactory mentioned in ootero solution is no longer available, so you should use either TomcatServletWebServerFactory or TomcatReactiveWebServerFactory according to your context.

The solution stays the same aside from the factory injection :

@Bean
public TomcatServletWebServerFactory servletContainer() {
    TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
    Connector[] additionalConnectors = this.additionalConnector();
    if (additionalConnectors != null && additionalConnectors.length > 0) {
        tomcat.addAdditionalTomcatConnectors(additionalConnectors);
    }
    return tomcat;
}

To change Actuator management port you can use property

management.port=8081

See full list of properties here

Update: Actuator creates one more Embedded Tomcat(servlet container) instance in this case. See here and here
