# Spring Boot 配置 HTTPS 访问 #

*  [相关代码][Link 1]

## 生成证书 ##

*  创建新证书

keytool -genkeypair -alias hellowood -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore hellowood.p12 -validity 3650
    输入密钥库口令:
    再次输入新口令:
    您的名字与姓氏是什么?
      [Unknown]:  HellWood
    您的组织单位名称是什么?
      [Unknown]:  HelloWood
    您的组织名称是什么?
      [Unknown]:  HelloWood
    您所在的城市或区域名称是什么?
      [Unknown]:  BJ
    您所在的省/市/自治区名称是什么?
      [Unknown]:  BJ
    该单位的双字母国家/地区代码是什么?
      [Unknown]:  CN
    CN=HellWood, OU=HelloWood, O=HelloWood, L=BJ, ST=BJ, C=CN是否正确?
      [否]:  y

这样就生成了 `hellowood.p12`这个证书

*  如果已经有一个证书，可以将该证书转换为 PKCS格式

keytool -import -alias hellowood -file hellowood.crt -keystore hellowood.p12
    // 或
    keytool -importkeystore -srckeystore hellowood.jks -destkeystore hellowood.p12 -deststoretype pkcs12

## 配置 HTTPS ##

*  将 `hellowood.p12` 添加到 `resources/`下
 *  application.properties

# SSL config
    server.ssl.key-store-type=PKCS12
    server.ssl.key-store=classpath:hellowood.p12
    server.ssl.key-store-password=123456
    server.ssl.key-alias=hellowood
    server.ssl.enabled=true

*  添加接口

@RestController
    public class BaseController { 
    
        @GetMapping("/")
        public String root() { 
            return "HelloWood";
        }
    }

*  启动应用，会看到日志中有提示应用使用 HTTPS 启动

2018-12-31 21:54:07.940  INFO 24001 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8080 (https) with context path ''

*  访问 `http://localhost:8080`，会提示需要使用 HTTPS 进行访问

curl http://localhost:8080/
    Bad Request
    This combination of host and port requires TLS.

*  访问 `https://localhost:8080`，会成功返回 HelloWood

curl --insecure https://localhost:8080
     HelloWood%

## 重定向 HTTP 到 HTTPS ##

*  修改端口，添加 HTTP 端口 (application.properties)

server.port=8443
    server.port.http=8080

*  添加重定向配置`ConnectorConfig.java`

import org.apache.catalina.Context;
    import org.apache.catalina.connector.Connector;
    import org.apache.coyote.http11.Http11NioProtocol;
    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.boot.web.servlet.server.ServletWebServerFactory;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class ConnectorConfig { 
    
        @Value("${server.port.http}")
        private int serverPortHttp;
    
        @Value("${server.port}")
        private int serverPortHttps;
    
        @Bean
        public ServletWebServerFactory servletWebServerFactory() { 
            TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory() { 
                @Override
                protected void postProcessContext(Context context) { 
                    SecurityConstraint securityConstraint = new SecurityConstraint();
                    securityConstraint.setUserConstraint("CONFIDENTIAL");
                    SecurityCollection securityCollection = new SecurityCollection();
                    securityCollection.addPattern("/*");
                    securityConstraint.addCollection(securityCollection);
                    context.addConstraint(securityConstraint);
                }
            };
            factory.addAdditionalTomcatConnectors(redirectConnector());
            return factory;
        }
    
        private Connector redirectConnector() { 
            Connector connector = new Connector(Http11NioProtocol.class.getName());
            connector.setScheme("http");
            connector.setPort(serverPortHttp);
            connector.setSecure(false);
            connector.setRedirectPort(serverPortHttps);
            return connector;
        }
    }

*  再次启动应用，看到日志中有 HTTP 和 HTTPS 的端口信息

2018-12-31 22:17:47.113  INFO 24612 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8443 (https) 8080 (http) with context path ''

*  访问 `http://localhost:8080`，将会被重定向到`https://localhost:8443`

curl -v http://localhost:8080
    * Rebuilt URL to: http://localhost:8080/
    *   Trying ::1...
    * TCP_NODELAY set
    * Connected to localhost (::1) port 8080 (#0)
    > GET / HTTP/1.1

*  访问 `https://localhost:8443`正常返回`HelloWood`

curl https://localhost:8443 --insecure
    HelloWood%
