騰訊雲服務器項目使用443端口

　　　　使用騰訊雲服務器，運行項目時，項目開啟端口443

　　　　

　　      同時實現80端口自動轉為443端口代碼：

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監聽的http的端口號
        connector.setPort(httpPort);
        connector.setSecure(false);
        //監聽到http的端口號后轉向到的https的端口號
        connector.setRedirectPort(serverPort);
        return connector;
    }
}

然后打包，部署項目至服務器，運行，一直報錯

 直到使用安裝nginx排查一下問題時，找到一篇文章這樣說：sudo su root ,

　　

再次運行項目：問題得到解決
