What server does jhipster use?

Question

I know you can build a WAR file to deploy to an application server, but what kind of server is created when you run the main Application class?

/**
 * Main method, used to run the application.
 */
public static void main(String[] args) throws UnknownHostException {
    SpringApplication app = new SpringApplication(Application.class);
    SimpleCommandLinePropertySource source = new SimpleCommandLinePropertySource(args);
    addDefaultProfile(app, source);
    Environment env = app.run(args).getEnvironment();
    log.info("Access URLs:\n-----------------------------------------------------\n\t" +
            "Local: \t\thttp://127.0.0.1:{}\n\t" +
            "External: \thttp://{}:{}\n-----------------------------------------------",
        env.getProperty("server.port"),
        InetAddress.getLocalHost().getHostAddress(),
        env.getProperty("server.port"));
}

By default spring-boot uses Tomcat. You can configure it to use Jetty or undertow(https://docs.spring.io/spring-boot/docs/current/reference/html/howto-embedded-servlet-containers.html). You can check your pom.xml and see if there are any references to them. If not, you can assume, it is tomcat. — jny, Nov 17 '15 at 18:03

And I (the author of JHipster) confirm it's Tomcat. – Julien Dubois Nov 19 '15 at 15:39

As of JHipster 3.7.0 (Ref http://www.jhipster.tech/2016/09/12/jhipster-release-3.7.0.html and https://github.com/jhipster/generator-jhipster/issues/4054) it's Undertow. – Naymesh Mistry Oct 19 '17 at 00:37

After version of 3.7.0 JHipster migrated to Undertow. The release note says:

Migration to Undertow is our biggest change - see #4054. This brings some very good performance enhancements in start up time and memory usage: this is good for everyone, but people doing microservices will benefit from it even more. With this change, JHipster uses nearly as much JBoss code (Undertow, Hibernate, Bean Validation, MapStruct) as Spring code!
