springboot中多端口启动（这里也适用于https既443端口）

application.properties中添加设置以下设置
#https证书
#修改默认端口号# https 加密端口号 443
server.port=${appPort:443}
#server.port=${appPort:8008}
server.additionalPorts=8008,8001//自定义属性可以为8008，8001，8003......添加任意

新建类xxxx (添加如下方法)

@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 (this.additionalPorts==null) {//这里你可以修改成判断他的长度和是否等于null
        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[] {});
}


在TwentyfourfinnerApplication中添加上面新建类
@SpringBootApplication
@MapperScan("com.xxxx.xxx.dao")
@Import({HttsConfig.class})//添加新建的类
public class TwentyfourfinnerApplication {

public static void main(String[] args) {

SpringApplication.run(TwentyfourfinnerApplication.class, args);
System.out.println("后台启动成功");
}

}
