Tencent cloud server project using port 443

　　　　When using Tencent cloud server, run the project, the project open port 443

　　　　

　　      While achieving 80 ports automatically converted 443 Code:

package com.jofiy.gaogao.config;

import org.apache.catalina.Context;
import org.apache.catalina.connector.Connector;
import org.apache.tomcat.util.descriptor.web.SecurityCollection;
import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
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;

@Configuration
public class CommonConfig {
    @Value("${http.port}")
    private Integer httpPort;
    @Value("${server.port}")
    private Integer serverPort;

    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = 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);
            }
        };
        tomcat.addAdditionalTomcatConnectors(httpConnector());
        return tomcat;
    }

    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        // Connector listening http port number 
        connector.setPort (httpPort ); 
        connector.setSecure ( to false );
         // listening to the port number to which a steering http https port number 
        connector.setRedirectPort (the serverPort );
         return Connector; 
    } 
}

Then package, deploy projects to servers running, has been an error

 Until use nginx install just the matter of the investigation, to find an article saying: sudo su root,

　　

Run the project again: the problem is resolved
