Springboot监听多个端口

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;

    @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[] {});
    }
}

　　

Springboot 2X

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

    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        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[] {});
    }
}

　　

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})
