SpringBoot Tomcat多端口启动

SpringBoot一个项目如果想用多个tomcat启动，那要怎么实现呢

Spring Boot 1.x.x

@SpringBootApplication
public class EventbusApplication {

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

    @Bean
    public EmbeddedServletContainerFactory createEmbeddedServletContainerFactory() {
        TomcatEmbeddedServletContainerFactory tomcatFactory = new TomcatEmbeddedServletContainerFactory();
        tomcatFactory.setPort(8080);

        return tomcatFactory;
    }

}

Spring Boot 2.x.x

@SpringBootApplication
public class EventbusApplication2 {

    public static void main(String[] args) {
        SpringApplication.run(EventbusApplication2.class, args);
    }

    @Bean
    public TomcatServletWebServerFactory createEmbeddedServletContainerFactory() {
        TomcatServletWebServerFactory tomcatFactory = new TomcatServletWebServerFactory();
        tomcatFactory.setPort(8086);
        return tomcatFactory;
    }

}
