我在ubuntu服务器上部署了我的springboot应用程序，它使用springsecurity进行安全保护。所以，我有一个问题，我只能使用url访问我的应用程序like:https：//示例。com:8443. 至于，为什么我要使用8443端口呢？似乎spring security使用8443端口。有什么解决方案可以帮助我访问url为的应用程序吗www.example.com? 我的相关代码如下：

spring.freemarker.cache=false
spring.datasource.url=jdbc:mysql://MyIp:3306/keziqu?serverTimezone=UTC
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
server.port=8443
server.ssl.key-store=classpath:**.pfx
server.ssl.key-store-password=password

# server.ssl.key-password=another-secret

logging.file.path=./log/

# logging.level.org.springframework.security=debug

@Configuration
public class TomcatConfig {

    @Bean
    TomcatServletWebServerFactory tomcatServletWebServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory(){
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint constraint = new SecurityConstraint();
                constraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                constraint.addCollection(collection);
                context.addConstraint(constraint);
            }
        };
        factory.addAdditionalTomcatConnectors(createTomcatConnector());
        return factory;
    }

    private Connector createTomcatConnector() {
        Connector connector = new
                Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(80);
        connector.setSecure(false);
        connector.setRedirectPort(8443);
        return connector;
    }
