如前所述，可以设置server.port和management.port沿着management.context-path属性，以使嵌入式容器监听不同的端口（访问Actuator端点的管理相关属性）。
要侦听server.port和management.port以外的端口，请执行以下操作：

@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[] {});
    }
}

我最近在博客上写了这个主题：

• Configuring Tomcat to Listen on Multiple ports using Spring Boot

由于springboot 2，ootero solution中提到的EmbeddedServletContainerFactory不再可用，因此您应该根据上下文使用TomcatServletWebServerFactory或TomcatReactiveWebServerFactory。
除了出厂注射外，解决方案保持不变：

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

要更改执行器管理端口，可以使用属性

management.port=8081

字符串
查看完整的属性列表here

**更新：**在本例中，Actuator会再创建一个Embedded Tomcat（servlet容器）示例。参见here和here

要在单个项目中运行2个或更多应用程序或更改默认端口，可以执行如下操作

@SpringBootApplication
public class NewApplication {
     public static void main(String[] args) {
         SpringApplication app = new SpringApplication(NewApplication .class);
         app.setDefaultProperties(Collections.singletonMap("server.port", "8083"));
         app.run(args);
     }
}

如果只需要打开一个额外端口，则以下操作就足够了（Kotlin）：

@Configuration
class AdditionalEndpointConfig {

    @Bean
    @ConditionalOnProperty(PORT_PROPERTY)
    fun tomcatServletWebServerFactory(@Value("\${$PORT_PROPERTY}") additionalPort: Int) =
        TomcatServletWebServerFactory().apply {
            addAdditionalTomcatConnectors(
                Connector("org.apache.coyote.http11.Http11NioProtocol").apply {
                    scheme = "http"
                    port = additionalPort
                })
        }

    companion object {
        const val PORT_PROPERTY = "server.additional.port"
    }
}
