步骤1：
application.yml配置文件中添加需要监听的端口如下所示additionalPorts为该服务添加的其他端口
server: port: 8088 additionalPorts: 8089,8087
步骤2：
新建TomcatUtil.java类，详细代码如下
Springboot 1X

package com.demo;import org.apache.catalina.connector.Connector;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;import java.util.ArrayList;
import java.util.List;@Configuration
public class TomcatUtil {@Value("${server.additionalPorts}")private String additionalPorts;@Beanpublic 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[] {});}
}Springboot 2X

}步骤3：
服务启动类中添加如下代码，添加位置如下图所示
@Import({TomcatUtil.class})
