Springboot中如何启用多个监听端口

@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[] {});
    }
}

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