如何使用 Spring Boot 2.3.1 将 http 流量重定向到 https

Question

下午好，我正在使用spring boot并且已经实现了http安全模式（https），但是我需要知道如何将http请求重定向到https，以及是否需要指定一个特定的安全端口，比如443，或者我可以用任何端口做到这一点。目前我使用端口 8080 8443

主类

package com.prueba.https;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class PruebaHttpsApplication {

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

}

请求类

package com.prueba.http.request;

public class PruebaRequest {

    public String nombre;

    public String getNombre() {
        return nombre;
    }

    public void setNombre(String nombre) {
        this.nombre = nombre;
    }

}

响应类

package com.prueba.https.response;

public class PruebaResponse {

    public String saludo;

    public String getSaludo() {
        return saludo;
    }

    public void setSaludo(String saludo) {
        this.saludo = saludo;
    }


}

控制器类

package com.prueba.https.controller;

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import com.prueba.http.request.PruebaRequest;
import com.prueba.https.response.PruebaResponse;

@RestController
public class PruebaController {


    @PostMapping(value = "/PruebaHTTPS") 
    public Object PruebaController(@RequestBody PruebaRequest req) {
        PruebaResponse res = new PruebaResponse();
        res.setSaludo("Hola " +req.getNombre());
        return res;

    }

}

应用程序属性

server.port=8443

server.ssl.key-store = classpath:keystore.p12
server.ssl.key-store-password = pass
server.ssl.keyStoreType = PKCS12
server.ssl.keyAlias = tomcat

更新

使用以下适用于我的 spring 版本的代码，但是它给我的 http 请求错误：

package com.prueba.https;
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.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@ComponentScan
@Configuration
@EnableAutoConfiguration
public class WebsocketSourceConfiguration {

      @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(getHttpConnector());
        return tomcat;
      }

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



}

HTTPS (8443)

HTTP(8443)

HTTP(8080)

为什么我不能指向 http:8443 并将我重定向到 https？

Answer 1

要将您的 HTTP 请求重定向到 HTTPS 请求，您需要添加以下配置：

@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;
}

我希望这对你有用。
