springboot 配置tomcat 开启多端口监听

Posted 2023-02-05 Freeguy88

配置文件 （application.yml）中配置端口号

server:
  port: 8008
  additionalPorts: 8009,8010

新建一个配置类进行配置

@Configuration
public class TomcatMultiPortConfig 

    @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.parseInt(port));
            result.add(connector);
        
        return result.toArray(new Connector[] );
