在使用k8s存活探针的时候，如果需要增加端口专门用于存活探针的调用端口，可以通过以下方式开启多个端口。

新增扩展端口

application.yml

server:
    port: 8120
    extensionPorts: 8121

配置Tomcat

EmbeddedTomcatConfig.java

package com.wenlincheng.pika.auth.config;

import org.apache.catalina.connector.Connector;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

@Configuration
public class EmbeddedTomcatConfig {

    @Value("${server.extensionPorts}")
    private String extensionPorts;

    @Bean
    public TomcatServletWebServerFactory servletContainer() {

        TomcatServletWebServerFactory tomcatWebServerFactory = new TomcatServletWebServerFactory();
        Connector[] additionalConnectors = this.additionalConnector();
        if (additionalConnectors != null && additionalConnectors.length > 0) {
            tomcatWebServerFactory.addAdditionalTomcatConnectors(additionalConnectors);
        }
        return tomcatWebServerFactory;
    }

    private Connector[] additionalConnector() {
        if (StringUtils.isBlank(this.extensionPorts)) {
            return null;
        }
        String[] ports = this.extensionPorts.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.parseInt(port));
            result.add(connector);
        }
        return result.toArray(new Connector[] {});
    }
}
