Spring Boot将端口8080重定向到8443

在Spring Boot 2.x中，我们可以创建一个ServletWebServerFactory来将端口从HTTP 8080重定向到HTTPS 8443 。

访问localhost:8080 ，它将重定向到localhost:8443

1. ServletWebServerFactory

对于Spring Boot 2.x，请尝试以下操作：

pom.xml

      org.springframework.boot
      spring-boot-starter-web
  

  
      org.springframework.boot
      spring-boot-starter-thymeleaf
  

StartApplication.java

package com.mkyong;

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.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class StartApplication {
    public static void main(String[] args) {
        SpringApplication.run(StartApplication.class, args);
    }

    // spring boot 2.x
    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                securityConstraint.addCollection(collection);
                context.addConstraint(securityConstraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(redirectConnector());
        return tomcat;
    }

    private Connector redirectConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8080);
        connector.setSecure(false);
        connector.setRedirectPort(8443);
        return connector;
    }

}

2. EmbeddedServletContainerFactory

对于Spring Boot 1.x，请尝试EmbeddedServletContainerFactory

@Bean
  public EmbeddedServletContainerFactory servletContainer() {
      TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory() {
          @Override
          protected void postProcessContext(Context context) {
              SecurityConstraint securityConstraint = new SecurityConstraint();
              securityConstraint.setUserConstraint("CONFIDENTIAL");
              SecurityCollection collection = new SecurityCollection();
              collection.addPattern("/*");
              securityConstraint.addCollection(collection);
              context.addConstraint(securityConstraint);
          }
      };

      tomcat.addAdditionalTomcatConnectors(redirectConnector());
      return tomcat;
  }

  private Connector redirectConnector() {
      Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
      connector.setScheme("http");
      connector.setPort(8080);
      connector.setSecure(false);
      connector.setRedirectPort(8443);

      return connector;
  }
