Change port of deployed Spring project on Wildfly - spring

Question

Note to moderator: Other existing questions in SO make reference to the default interface. I'm not interested on changing that. I need to specifically change the port of each deployment.
Other questions regard wildfly running in standalone mode. I'm running it as a Windows Server Service.
Based on this please do not close the question.
Now, the question:
Taking as a reference the following Spring application, running on Wildfly on Windows Server 2019 installed as a service:
#Configuration
#SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
static Logger logger = LoggerFactory.getLogger(DemoApplication.class);
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<DemoApplication> applicationClass = DemoApplication.class;
}
When I was using Tomcat, changing the web service port was easy as adding:
Application.properties
server.port=8093
Resulting in the desired URL:
http://127.0.0.1:8093/swagger-ui.html
However, deploying on Wildfly proved to be harder. At first, it was the .war name and the wrong context root, which I fixed by adding the following changes:
pom.xml
<finalName>${project.artifactId}</finalName>
src\main\webapp\WEB-INF\jboss-web.xml
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.jboss.com/xml/ns/javaee
http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd">
<context-root>/</context-root>
</jboss-web>
However, there's the last problem. The web service is being exposed on http://127.0.0.1:8080/swagger-ui.html instead of using port 8093.
How can I change the port of each deployed web service in Wildfly, instead of the default 8080?

The server.port property only controls the listening port of an embedded server in a Spring boot app (tomcat, jetty, etc.).
The app's port in a standalone application server is specified during the deployment. The easiest way to do this on Wildfly is via the wildfly-maven-plugin (https://docs.jboss.org/wildfly/plugins/maven/latest/deploy-mojo.html):
