Configure Spring Boot with two ports

Question

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